The Egyptian caucasiod in the brain size section

I oppose this statement since its not comparable; the Egyptian people are 85 millon while the massai are 1.5 million. There are many mixed ethinc group within Egypt including many blacks. And many minorities within Egypt. A country(Egypt) can not be compared to specific people(Massai) --MasriDefend (talk) 04:36, 17 March 2012 (UTC)

Title change suggestion per "Ancient Egyptian race controversy‎"

I just noticed that the article once called Race of the Ancient Egyptians is now "Ancient Egyptian race controversy‎" I'm really happy to see this title chance and wonder if we could do something similar with this article. It is an article about a controversy. What do others think of a new title along the lines "Controversy over race and Intelligence" or "Race and intelligence controversy" ? futurebird (talk) 04:24, 23 February 2012 (UTC)

Yup. Makes a lot of sense. AndyTheGrump (talk) 04:30, 23 February 2012 (UTC)

Yes.VolunteerMarek 04:41, 23 February 2012 (UTC)

Opposed. The new title would make it sound like this article is just about the controversy, rather than about the data as well. The comparison with "Ancient Egyptian race controversy" doesn't hold up because that article is separate from Population history of Egypt. 110.32.203.16 (talk) 06:34, 23 February 2012 (UTC)

Opposed. There is no dispute that there exists average test score differences. The controversy is regarding how to interpret this. Acadēmica Orientālis (talk) 07:19, 23 February 2012 (UTC)

No opinion. Been in one too many WP article naming battles that aren't based on Wikipedia:Article titles but veer instead into wrestles over suitable codespeak for how best to "package" or immunize against a problematic misinterpretation in a marketing sense. To me, "controversy" in the name shouts "editorial euphemism" because I don't see it labeled thus much in the literature. There is a controversy, no doubt. But authorities writing about it aren't so obsessively focused on how to label the issue. Here on wp we too often get sucked into what to label topics as opposed to focusing our efforts on appropriately describing them.Professor marginalia (talk) 07:55, 23 February 2012 (UTC)

Oppose Race and intelligence is the name commonly used[1] to refer to this topic in reliable sources.--Victor Chmara (talk) 11:58, 23 February 2012 (UTC)

Oppose Use the common name for the topic. We're not in the business of writing articles within the title. Dmcq (talk) 14:29, 23 February 2012 (UTC)

Support. We don't have articles on data, we have articles on areas of knowledge. In this case, all claims about the relationship between race and intelligence are controversial. it is the controversies that make it notable. The name change would be highly appropriate. Slrubenstein | Talk 20:40, 25 February 2012 (UTC)

'Data' and 'areas of knowledge' are highly overlapping categories; this article is about both. Your middle 2 sentences I fail to comprehend. 110.32.129.67 (talk) 08:55, 28 February 2012 (UTC)

• Oppose Race and intelligence is the name of the topic. Reasons given for the name change are extremely weak and are just a cover for the a POV pushing tactic where information relevant to racial differences in intelligence can be cut out of an article on just the "controversy". TheTrunchbull. (talk) 17:26, 26 February 2012 (UTC)

• Totally - should be moved to "US-American controversy about ..."
  

Are you people even aware that the "whole article" is about American (sigh!) this, American (sigh!) that - APA, AAA, and so on ?
I did NOT read this whole "thing" (still respect! to those who bother/ed to put in some perspective), but everywhere I jumped it was American blabla here and American soso there - which btw. I'd appreciate if it were altered to US-American.
If you can't come up with anything reliable from outside your own little world (them US of A), then maybe it isn't all that factual, scientific, etc. ?
With en.WP being so "inclusionist" to allow articles on practically everything, at least have it under an appropriate name, not suggesting that this is representing a worldwide accepted reflection of "scientific", "reliable" anything. kthxbye Pardon my German (Fiiiisch!)

Neanderthal DNA , genetic variation = higher IQ?

I'm not a racist or anything, but given the recent discovery that Neanderthal DNA is found in quantities ranging from 1-4% in Eurasians, could this have an effect on intelligence - or at the very least the way that Eurasians think - which would mean that IQ tests favour those with Neanderthal DNA? There is also speculation that there are links to autism as a result, as there is a far lower incident rate of it in those of African descent; I believe that on average high-functioning autistics typically have an above-average IQ (but I'll leave that to someone more knowledgeable, I'm just 'throwing it out there'). groovygower (talk) 23:07, 16 April 2012 (UTC)

There was some early speculation that the Microcephalin gene which has been linked to IQ (the link still being hotly disputed) might of come from the Neanderthals, but when the Neanderthal genome was sequenced it wasn't there. This might not be a definitive refutation of the idea because who knows maybe there were other Neanderthals who had the gene, but I wouldn't bet on it. I don't know much about the issue of Neanderthal admixture, but my general understanding is that all non-African populations have some Neanderthal ancestry, which would presumably include low IQ groups like the Australian Aboriginals.B.B. (talk) 05:04, 19 April 2012 (UTC)

Ridiculous speculation: see WP:NOTFORUM AndyTheGrump (talk) 05:33, 19 April 2012 (UTC)

Stereotype Threat: Wicherts & de Haan

I'm not entirely sure if the inclusion of this is appropriate in this article. This seems to be the only source I could find in my search that could potentially disprove stereotype threat. However, the primary issue with this is that this was presented at a conference, and nothing more than that short introduction in the link can be found online. I don't believe it is justified to include the one piece of unverifiable evidence that counters the large amount of evidence supporting stereotype threat. — Preceding unsigned comment added by 216.165.95.72 (talk) 03:54, 17 April 2012 (UTC)

Good call. Unfortunately is article has been subjected to years of concerted POV pushing and is rife with such nonsense from scientific racists and their support groups like the ISIR. Without more eyes I fear it may never be corrected. —ArtifexMayhem (talk) 05:49, 17 April 2012 (UTC)

It seems fair to withhold citing Wicherts & de Haan's work on stereotype threat until it is actually published. However there is some indirect evidence that stereotype threat is only salient in low-stakes laboratory settings that could be worth mentioning. I also object to the characterization of ISIR as a support group for "racists". Their website indicates a number of influential advocates for an environmental explanation for racial differences in cognitive ability such as James R. Flynn, Robert J. Sternberg, Jelte M. Wicherts, Conor V. Dolan, etc are members. Sure, numerous advocates for the hereditarian model are also members, but that is only because the ISIR accurately reflects the diversity of opinion within the scientific community that specializes in this field of inquiry.B.B. (talk) 04:47, 19 April 2012 (UTC)

"...this field of inquiry" being the promotion of racism... AndyTheGrump (talk) 05:37, 19 April 2012 (UTC)

No opinion about the ISIR because it doesn't matter. The claim was weak, get rid of it. It wasn't published, so it's unlikely to carry much weight in the field. Professor marginalia (talk) 06:24, 19 April 2012 (UTC)

Er, yes. The 'ISIR' appears to be a website run by who knows who, with all the credibility of a Pokomon fanzine. AndyTheGrump (talk) 06:30, 19 April 2012 (UTC)

Also... 1) No it is not worth mentioning that "there is some indirect evidence that stereotype threat is only salient in low-stakes laboratory settings". Casting doubt on a widely studied, well documented and highly supported phenomena (as in actually exists) would require more than a single article of no particular note. It is best to stick with review articles like this one and avoid primary sources (or fake "review" articles of the Jensen and Ruston kind). 2) Please do not propagate the myth (as in fictional) that there is a 100% environmental camp. 3) What Andy said. —ArtifexMayhem (talk) 06:37, 19 April 2012 (UTC)

I'm with you in terms of going for good quality review articles. But that one is probably better used in the stereotype threat article because its focus is so specific to the cognitive machinery involved.Professor marginalia (talk) 07:03, 19 April 2012 (UTC)

I don't disagree. I admit to my laziness... I needed an example and it was handy. —ArtifexMayhem (talk) 07:23, 19 April 2012 (UTC)

The ISIR publishes the peer-reviewed journal Intelligence. Going by their respectable impact factor, the scientific community doesn't appear to share AndyTheGrump's opinion that they have "all the credibility of a Pokomon fanzine".

I was disputing a specific aspect of the stereotype threat phenomena, not stereotype threat as a whole. There is significantly less data on stereotype threats relationship to test outcome in high-stakes non-laboratory settings than there is in low-stakes laboratory environments. Reading "An Integrated Process Model of Stereotype Threat Effects on Performance", the only evidence they cite against the claim that stereotype threat has little impact outside of the laboratory is a single article on gender stereotype threat that is a reanalysis of Stricker and Ward's data by Danaher and Crandall. Stricker and Ward have published a rebuttal to Danaher and Crandall's claims, which to my knowledge hasn't been refuted. It is also worth noting that Stoet & Geary recently published an article in the Review of General Psychology disputing the significance of gender stereotype threat as an explanation for the male/female gap in mathematics and achievement.

Also, how did I "propagate the myth that there is a 100% environmental camp"?B.B. (talk) 18:06, 23 April 2012 (UTC)

What the heck happened to all the stereotype threat references here? Most if not all of those sources should be summarized and cited in the section! 71.215.84.127 (talk) 04:48, 7 May 2012 (UTC)

I'm actually a research assistant under Joshua Aronson (one of the main researchers of stereotype threat along with Claude Steele). I discussed the Wicherts study with him recently, and he told me he actually did a review of this, and that the Wicherts study only found that stereotype threat doesn't exist in some specific situations. I'm going to search for this review and hopefully clear this section up. Rev0lverPH (talk) 03:45, 4 May 2012 (UTC)

Omission of what is "variation between different racial groups" in lead

The current lead states:

"IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause."

But what the variation is for some reason strangely omitted. Suggested to change to:

"IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups. With the average score of the African American population being lower than that of the European-American population and the average score of Asian American population being higher than that of the European-American population. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause.

If the lead is going to mention that there is "variation between different racial groups" it should also mention what that variation is. Omission of such a central focus of this subject is odd to say the least. Altetendekrabbe has an issue stating undue weight to American differences. As these variations consistently exist outside the US as well, the following is proposed:

"IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups. With the average score of those with African ancestry lower than that of European ancestry and the average score of those with East Asian ancestry being higher than that of European ancestry. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause." BlackHades (talk) 10:23, 12 July 2012 (UTC)

I find issue with the statement "and individuals of each group can be found at all points on the IQ spectrum." at the introduction.

This just looks like hogwash. The asian american IQ bell curve is far more to the right than the african american IQ bell curve, meaning that at some points on the IQ spectrum, notably at the much higher IQ ranges, there will be virtually no african americans but still a statistically significant amount of asian americans. I believe this inaccurate statement should be removed or replaced. RhymeNero (talk) 04:56, 12 May 2012 (UTC)

Why do you think that what 'you believe' is of any relevance to Wikipedia article content? AndyTheGrump (talk) 05:04, 12 May 2012 (UTC)

Because it is false information. It is indeed not a belief. Can you provide me with a reliable source that specifically states that all races are represented on all points of the IQ spectrum? RhymeNero (talk) 05:08, 12 May 2012 (UTC)

No. Because 'race' isn't a meaningful biological concept when referring to Homo sapiens. However, I'd recommend a little study of statistics too. Even if it were true (which it isn't) 'virtually no', isn't incompatible with 'individuals of each group'. If this is false information, provide a source that says so. Or troll elsewhere. AndyTheGrump (talk) 05:15, 12 May 2012 (UTC)

If it's not a "meaningful biological concept", then the article has no purpose at all. Then why are you even editing this page? You can recommend the article for deletion, if you feel so strongly. 221.120.115.125 (talk) 12:57, 18 July 2012 (UTC)

That race isn't a meaningful biological concept are your personal opinions, and yours only; not scientific assessments. And I'm sure there are IQ points where there are no african americans at all, virtual or real. I've done courses in statistics so don't lecture me on them. The fact is, race is no different to what we see in breeds of dog. Evolutionary pressures have pushed humans in different geographic locations to develop differently, both physically and mentally. There are enough differences between humans of these different locations to be taxonomically worthy. RhymeNero (talk) 05:25, 12 May 2012 (UTC)

The 'fact is' you don't have a clue what you are talking about. We don't give a toss about your ignorant and bigoted opinions on subjects you know nothing about (which seems to include statistics too. Since when is what you think you are 'sure of' a valid statistical measure?). Wikipedia articles are based on published reliable sources, not the ignorant ramblings of those who can't even be bothered to actually research the subjects they are commenting on. AndyTheGrump (talk) 05:37, 12 May 2012 (UTC)

Anyone who wants to take such a dogmatic stand needs first to re-read the second sentence of the article - "There are no universally accepted definitions of either race or intelligence in academia." With such uncertainty, no claim such as RhymeNero's can be made with any confidence at all. (In my view that sentence makes this whole article a candidate for deletion on the basis that it's bigoted, speculative nonsense, but I haven't won that argument yet.) HiLo48 (talk) 05:40, 12 May 2012 (UTC)

Then ANY article involving race has also the same uncertainty. By your logic then, any article about race would be deleted.221.120.115.125 (talk) 13:19, 18 July 2012 (UTC)

You see what people like me have to put up with? Bigoted fools like Andy who spit in your face and hurl abuse when presented with valid sensible hypotheses. So for other animals sub species can exist but somehow this mythical human race transcends species sub divisions? Humans are animals just like the rest and we have human sub species that given enough time would have diverted into fully different species themselves. That's what happened with us and the chimpanzees and us with the Neanderthals. And if you cannot accept that, the bigoted fools are you two. The only reason sensible views such as mine aren't mainstream is because of political correctness. If you think politics is a good enough reason to censor scientific research then you don't deserve to be editing wikipedia articles right now. RhymeNero (talk) 05:47, 12 May 2012 (UTC)

See WP:NOTFORUM. This isn't a platform for you to spout ignorance from... AndyTheGrump (talk) 05:53, 12 May 2012 (UTC)

And neither is this one for your ignorance. It is clear that your beliefs stem from your politics and there is no effort of neutrality on your part. You're just an angry little leftist liberal who's all for freedom of speech until it offends your sad little opinions. You have a weak mind. That is all. RhymeNero (talk) 06:02, 12 May 2012 (UTC)

See WP:TP for how to indent replies, and WP:TPG for the purpose of this page (hint: it's not a forum for expressing personal opinions, and particularly not a place to settle scores). Johnuniq (talk) 07:46, 12 May 2012 (UTC)

"And I'm sure there are IQ points where there are no african americans at all, virtual or real." Except that Philip Emeagwali, IQ of 190, is quite African, although not from America. I am afraid the mathematics of the bell curve are quite against you on this one. Besides, racial standard deviation, not racial mean, will determine the number of high IQ individuals. Rip-Saw (talk) 05:04, 29 August 2012 (UTC)

Claims of Philip Emeagwali's assorted achievements are dubious B.B. (talk) 19:59, 31 August 2012 (UTC)

Assumption in the lead

Currently we lead with: "The connection between race and intelligence has been a subject of debate in..."

Given two major points of the "controversy" are the use of "race" (Is that a sub-species or just skin-color?) and "intelligence" (Did you mean IQ, g or other?): Why are stating that there is a connection between these undefined concepts in the first line? —ArtifexMayhem (talk) 09:10, 28 July 2012 (UTC)

Because that's what reliable sources say. "Race and intelligence" is the rubric under which this topic is discussed in most sources. For example, in their article called "Race and intelligence" in The Cambridge Handbook of Intelligence (2011), Daley and Onwuegbuzie begin by saying that "The debate over racial differences in intelligence remains one of the most hotly contested issues in the social sciences today", and then attempt to contest the meaningfulness of the two concepts. In the same book, Earl Hunt writes that "We now come to what is possibly the most explosive topic in psychology -- the discussion of racial/ethnic differences in intelligence", and goes on to discuss both hereditarian and environmental theories of race differences in a balanced way. Racial differences in intelligence is how this topic is framed in reliable sources, regardless of how the two concepts are defined by different researchers. This article should reflect this fact.--Victor Chmara (talk) 11:14, 28 July 2012 (UTC)

My concern is that we are supporting the framing used by scientific racists, such as Hunt, as correct per the lead. — ArtifexMayhem (talk) 10:06, 8 August 2012 (UTC)

You may think that everybody who does not accept your views is a "scientific racist", but that's neither here nor there. Moreover, as I pointed out above, those who argue against hereditarian explanations of racial differences also use the same framing. It's not a "scientific racist" framing but simply a scientific one.--Victor Chmara (talk) 10:51, 8 August 2012 (UTC)

American Anthropological Association statement in the intro

This statement has multiple problems. It supports a minority point of view when there is nothing to balance with the majority viewpoint. Also, the AAA has not, as far as I have seen (correct me if I'm mistaken) done anything else to do with this debate, so surely a statement by them is less necessary, especial in the intro, then that by even 1 actually involved person like James Flynn or Richard Lynn? 110.32.146.96 (talk) 10:21, 23 July 2012 (UTC)

The AAA with its 11,000 members is one of the biggest professional organizations of scholars and practitioners in the field of anthropology. I believe that whenever they release an official statement it supports a majority point of view within the field. FonsScientiae (talk) 21:06, 24 July 2012 (UTC)

But the question of R&I is not anthropology. Why? The question is whether the gap is genetic or not, and since race is genetic, the question is about whether the intelligence gap is genetic, making the debate psychological. Since we're on the topic, perhaps the survey should be mentioned in the intro. 110.32.155.210 (talk) 08:19, 29 July 2012 (UTC)

The AAA is a crypto-political propaganda organization controlled by Marxist Jews for the last 100 years. They are liars and frauds. 119.196.38.20 (talk) 06:52, 15 September 2012 (UTC)

inconclusive studies

i just noticed that a lot of the subsections in the "genetic arguments"-chapter speak about either low correlations or inconclusive results. i don't see the point of providing that much space to such studies. totally undue. why not summarize and merge into a single section?-- altetendekrabbe  19:48, 21 July 2012 (UTC)

Most of those studies are indeed not very informative, but the fact is that reliable sources devote a lot of space to these few studies, which means that they should be discussed here at some length, too.--Victor Chmara (talk) 21:05, 21 July 2012 (UTC)

sure they should be discussed but they are really taking a lot of space, rendering the page difficult and frustrating to read. you read a whole section... and you find out it's nothing really there.-- altetendekrabbe  21:51, 21 July 2012 (UTC)

On the contrary. The fact that there are arguments put forward and given prominent coverage, but that studies have failed to produce significant or substantial evidence for them, is in itself a significant fact. It is missing the point to say "it's nothing really there". JamesBWatson (talk) 14:00, 25 September 2012 (UTC)

This article should be deleted

The fact that this article uses race as an explanation to the different levels of intelligence is a racist act. Moreover, all the "warning signs" in the opening of the article is another prove for the many problems in this article. Therefore, I believe this article is not appropriate and should be deleted.(ScottyNolan (talk) 16:58, 2 August 2012 (UTC))

Cry me a river. There is a vast academic literature on this topic, easily fulfilling the standards of WP:NOTABILITY and WP:VERIFIABILITY. See also WP:NOTCENSORED.--Victor Chmara (talk) 17:59, 2 August 2012 (UTC)

I also believe that this article fulfills the requirements for those three guidelines. You should review them. They're there for a reason, for situations such as this one. Lighthead...KILLS!! 06:51, 8 August 2012 (UTC)

The OP is completely right. The second sentence of the article begins "There are no universally accepted definitions of either race or intelligence in academia..." To have such a large article based on such uncertainty is just bullshit. HiLo48 (talk) 09:21, 8 August 2012 (UTC)

Universal means everyone on the planet agrees with it. As in, even people that are uneducated and cannot do basic fractions much less understand bulletproof mathematics and statistics based arguments serving as the foundation for the concept of IQ. If anything, the statement about it not being universal is irrelevant. It's like saying 2+2=4 is not universally accepted... — Preceding unsigned comment added by 71.59.28.166 (talk) 12:03, 6 October 2012 (UTC)

Many article subjects have no universally accepted definition, e.g. Race (human classification), Intelligence, Art and Kindness. That is no reason to delete an article.Sjö (talk) 09:54, 8 August 2012 (UTC)

It's a reason to delete any part of the text that is written as if there is a universally accepted definition. That would leave very little, and what would be left would be pretty pointless. Face the truth. This article simply provides a platform for racist bigots to stand on. Very ugly HiLo48 (talk) 19:47, 8 August 2012 (UTC)

I'm not in any way comparing Wikipedia to the ACLU but, does anybody think that the ACLU supports neo-Nazis? They defend them in court because they want to show all sides of the issue. Same thing here, if something exists we can't just put our heads in the sand no matter how offensive the topic is. Especially if the article meets the requirements per WP:NOTE. Accept it, the article is here to stay. Wikipedia should be as transparent as possible. Lighthead...KILLS!! 20:33, 8 August 2012 (UTC)

So if one person challenges any definition, we have to delete all text using that word? This is probably the most ridiculous statement I have ever read. It's lucky you have some name calling to change the subject. 119.196.38.20 (talk) 06:57, 15 September 2012 (UTC)

Noting academic opposition to research in lede

It is no surprise that few scientists are actually researching in this area, outside your Jensens and Rushtons because no scientist want their academic record discredited for being 'racist'.

I want to add this to the introduction: "In any case, due to the highly controversial and sensitive nature of this topic, very few scientists will even consider participating in any research of this type, leading to considerable academic literature skewed in favor of environmental causes but very little research supporting any genetic reasons, which is seen as politically incorrect. Indeed, Bruce Lahn, tenured professor at the University of Chicago, who was studying gene variance in the brain in different populations, retreated from his research after an academic backlash against the implications of his work went so far as to threaten his tenure at the university."

This is the same OLD original research and POV pushing just done by a NEW single purpose account. No. Volunteer Marek  20:31, 7 October 2012 (UTC)

Looking at your contributions, I can say the same thing. All I see is POV pushing. How is what I have written original research if it is backed up by a wall street journal article? In any case I disregard your opinion completely.YvelinesFrance (talk) 20:42, 7 October 2012 (UTC)

No, the source doesn't say what you are pretending it says. Volunteer Marek  20:53, 7 October 2012 (UTC)

The source describes a backlash due to research in a controversial topic. What about that do you not comprehend? I don't see what I wrote as incendiary anyway so I don't understand your problem. It's obvious that scientists do not want to research race and intelligence because of the sensitive nature of the topic. Do you disagree? This information should be included in the article. YvelinesFrance (talk) 20:56, 7 October 2012 (UTC)

You are misrepresenting the source. AndyTheGrump (talk) 21:00, 7 October 2012 (UTC)

I don't see this as misrepresenting the source, either. Here is what the source that YvelinesFrance linked to says:

"The 37-year-old Dr. Lahn says his research papers, published in Science last September, offered no view on race and intelligence. He personally believes it is possible that some populations will have more advantageous intelligence genes than others. And he thinks that "society will have to grapple with some very difficult facts" as scientific data accumulate. Yet Dr. Lahn, who left China after participating in prodemocracy protests, says intellectual "police" in the U.S. make such questions difficult to pursue."

And this is what it says about why Bruce Lahn stopped researching the topic:

"Dr. Lahn stands by his work but says that because of the controversy he is moving into other projects. Earlier this year, Mr. Easton of the university's media department forwarded Dr. Lahn a paper by two economists looking at the IQ of infants of different races. Dr. Lahn wasn't interested. "I'm surprised anyone studies this," he replied in an email."

How is YvelinesFrance's summary inconsistent with that? Zeromus1 (talk) 22:05, 7 October 2012 (UTC)

Nice thing about these little flare ups is that they tend to flush out the sockpuppet accounts. Volunteer Marek  22:29, 7 October 2012 (UTC)

You're saying this misrepresents the source, but you're refusing to explain how even when I quote the parts of the source that support it. How do you think this is helpful? If you could say "This part of the summary is unsupported by the article" then we could find a way to summarize it that would satisfy you, but you're just trying to shut down discussion by commenting on the other editors instead of the content.

How about "an academic backlash against the implications of [Lahn's] work went so far as to threaten his tenure at the university" for a start? The source says no such thing. AndyTheGrump (talk) 23:24, 7 October 2012 (UTC)

In any case, due to the highly controversial and sensitive nature of this topic,^{[not in citation given]} very few scientists will even consider participating in any research of this type,^{[not in citation given]} leading to considerable academic literature skewed in favor of environmental causes^{[not in citation given]} but very little research supporting any genetic reasons,^{[not in citation given]} which is seen as politically incorrect^{[by whom?]}. Indeed, Bruce Lahn, tenured professor at the University of Chicago, who was studying gene variance in the brain in different populations,^{[not in citation given]} retreated from his research after an academic backlash against the implications of his work went so far as to threaten his tenure at the university.^{[not in citation given]}

Looks like a gross misrepresentation of the source to me. — ArtifexMayhem (talk) 23:35, 7 October 2012 (UTC)

AndyTheGrump's summary sounds pretty good, but we should wait for YvelinesFrance's opinion. I think he wanted to mention that Lahn moved away from researching this topic because of the controversy. I quoted the part of the WSJ article that supports this, so I don't understand why everyone is claiming the article doesn't support it. What part of "because of the controversy he is moving into other projects" isn't clear? Zeromus1 (talk) 23:43, 7 October 2012 (UTC)

The part that defines "the controversy" as primarily concerning research "which is seen as politically incorrect" as opposed to Lahn's confusing correlation with causation. — ArtifexMayhem (talk) 01:41, 8 October 2012 (UTC)

The article quotes Harpending as saying, "I think that Bruce doesn't understand political correctness" as an explanation for the controversy. It also mentions that the association reported by Lahn may or may not stand up, but doesn't say anything him confusing correlation with causation. You are saying that to avoid misrepresenting the source, we must avoid mentioning something that the source mentions, and should instead say something the source doesn't say. How do you justify that? Zeromus1 (talk) 02:08, 8 October 2012 (UTC)

It wasn't a suggestion. The "political correctness" quote is Harpending using the standard defense of those that share his beliefs and should not be presented in Wikipedia's voice. — ArtifexMayhem (talk) 02:51, 8 October 2012 (UTC)

I think mentioning Lahn in the lede would be giving his situation undue weight, but there certainly seems to be a need to mention in the lede that at least one reason you don't find a lot of research on this matter is because it inherently generates controversy and hostility that many researchers would rather avoid. The WSJ article includes several quotes on that matter:

“ But some research is raising tensions as scientists such as Dr. Lahn venture into studies of genetic differences in behavior or intelligence . . . Other research is starting to explain variations in human skin color and hair texture. But scientists tense up when it comes to doing the same sort of research on the brain . . . Several groups of scientists have sent letters to Science criticizing the papers. ”

The wording suggested by Yvelines is a bit too editorialized, but this article can certainly be used to note the impact the controversy has on attempts at researching the subject.--The Devil's Advocate (talk) 18:09, 8 October 2012 (UTC)

Would you be willing to try proposing a new wording, that improves on the wording YvelinesFrance suggested? Zeromus1 (talk) 08:09, 9 October 2012 (UTC)

Perhaps something like: "Research into genetic causes for intellectual differences between racial groups is controversial and faces resistance in the scientific community due to concerns about the social implications of such research." That would be sufficiently short and generalized for the lede, while representing the source well.--The Devil's Advocate (talk) 16:02, 9 October 2012 (UTC)

Artifex Mayhem, do you have a Bachelor of Science degree from Harvard? Do you have a Phd from MIT? Do you have a professorship at one of the most prestigious universities in the world? What makes you think someone of Lahn's stature would confuse cause and correlation, one of the most basic mistakes of first year undergraduates of statistical courses? Your statement is humorously inane. In any case I am happy to see that a few other editors agree that research in this topic is very limited, at least in terms of using actual genetic data rather than fallible sociological studies that pose as scientific ones. Perhaps an editor better than I could come up with a better way to describe this phenomenon though I am fully willing to do it myself. YvelinesFrance (talk) 18:11, 9 October 2012 (UTC)

YvelinesFrance, do you approve of the wording suggested by The Devil's Advocate in the comment above yours? Zeromus1 (talk) 12:11, 10 October 2012 (UTC)

Yes I do, it's much more succinct than my own words. YvelinesFrance (talk) 15:59, 10 October 2012 (UTC)

The suggested wording is not supported by the source provided. — ArtifexMayhem (talk) 17:56, 10 October 2012 (UTC)

I agree with the wording in the lede suggested by The Devil's Advocate. It is succinct and it is surely not controversial to suggest that this is a controversial subject. --- Asteuartw (talk) 20:06, 10 October 2012 (UTC)

I also agree with The Devil's Advocate's wording, and I think we should go ahead and add it to the article. It looks to me like ArtifexMayhem is just being obstructionist here, and that shouldn't prevent us improving the article. Zeromus1 (talk) 20:18, 10 October 2012 (UTC)

How is my suggesting wording not supported? Look at these excerpts from the source:

Dr. Lahn had touched a raw nerve in science: race and intelligence . . . But some research is raising tensions as scientists such as Dr. Lahn venture into studies of genetic differences in behavior or intelligence . . . Other research is starting to explain variations in human skin color and hair texture. But scientists tense up when it comes to doing the same sort of research on the brain. Sociologist Troy Duster, who studies the use of racial categories by geneticists, worries that scientists will interpret data in ways that fit their prejudices. He cites the sorry history of phrenology, a study of skull shapes popular in the 19th century, and other pseudoscientific techniques used to categorize people as inferior . . . John Easton, head of media relations at the medical school, says his office was worried the work could be misinterpreted and abused by racist groups.

Now, some of that pertains specifically to Lahn's research, but several of those quotes clearly address the broader issue of there being resistance to research into race and intelligence due to concerns about the social implications. There are some additional sources that are of interest to this question: [2] [3] [4] [5] [6]. If you think the WSJ source is not quite sufficient then maybe some of these will do it.--The Devil's Advocate (talk) 22:35, 10 October 2012 (UTC)

More specifically, the claim that the "research" itself faces "faces resistance" because of the possible "social implications" is not supported. It is Lahn's conclusions that are not supported. Other scientists are resistant to those conclusions specifically because they are not supported by the science (in this case Lahn's own research). — ArtifexMayhem (talk) 23:28, 10 October 2012 (UTC)

See the quotes "some research is raising tensions" and "scientists tense up when it comes to doing the same sort of research on the brain" as those directly point to the research itself facing resistance. The other sources provided more clearly point to this resistance.--The Devil's Advocate (talk) 23:46, 10 October 2012 (UTC)

And that resistance may or may not be based on "social implications" (i.e. political correctness). — ArtifexMayhem (talk) 05:36, 11 October 2012 (UTC)

The quotes "worries that scientists will interpret data in ways that fit their prejudices" and "his office was worried the work could be misinterpreted and abused by racist groups" point to the resistance being about the social implications. Scientists are concerned, understandably so, that such research could seemingly legitimize arguments of white racial superiority. In the Independent article there is another such quote: "Sabeti says that she has not found any evidence in her haplotype analysis to support Lahn's findings, and she freely admits that this is a relief. 'This is a very delicate time, and a dangerous time, as people start to come up with things that the general public, or the media, or various groups might misinterpret.'" Also see the Nature article "Claims that sex- or race-based IQ gaps are partly genetic can offend entire groups, who feel that such work feeds hatred and discrimination. Pressure from professional organizations and university administrators can result in boycotting such research, and even in ending scientific careers." We have several sources now that can support the statement.--The Devil's Advocate (talk) 15:25, 11 October 2012 (UTC)

That's quite excellent, all we need now is a summary of it in the article itself. YvelinesFrance (talk) 17:59, 11 October 2012 (UTC)

They always write the same thing when they don't like it. "You're misrepresenting the source and you are a sockpuppet". They are liars, that's all. — Preceding unsigned comment added by 112.218.41.83 (talk) 10:38, 12 October 2012 (UTC)

That's because usually you are misrepresenting the source and you are sockpuppets.  Volunteer Marek  14:56, 16 October 2012 (UTC)

I've found another source that could be useful, it's from the Economist (http://www.economist.com/node/21564191):

It is not, however, a view that cut much ice in 20th-century social-scientific thinking, particularly after the second world war. Those who allowed that it might have some value were generally shouted down and sometimes abused, along with all others vehemently suspected of the heresy of believing that genetic differences between individuals could have a role in shaping their behavioural differences. Such thinking, a product compounded of Marxism (if character really is ingrained at birth, then man might not be perfectible) and a principled rejection of the eugenics that had led, via America’s sterilisation programmes for the “feeble minded”, to the Nazi extermination camps, made life hard for those who wished to ask whether genes really do affect behaviour.

It looks like we have more than enough evidence to put this information in the article, I will do so myself in a short delay. YvelinesFrance (talk) 22:16, 13 October 2012 (UTC)

Utter garbage - the article isn't about 'race and intelligence' at all. Stop wasting our time with nonsense. AndyTheGrump (talk)

Behaviour, the ability to make rational or irrational decisions stems from the brain and hence is very related to intelligence. The article may not be about intelligence and race proper but the quote itself is about the bias in academic circles against hereditarian approaches. Basically the kind of bias and knee jerk reaction that you yourself are putting on full display. YvelinesFrance (talk) 02:26, 14 October 2012 (UTC)

It isn't about race and intelligence. As for 'bias', <- redacted -> look in a mirror sometime. AndyTheGrump (talk) 02:31, 14 October 2012 (UTC)

To decide that certain hypotheses are just plain wrong or inappropriate is not a sign of bias. It's a sign of wisdom. HiLo48 (talk) 02:35, 14 October 2012 (UTC)

Andy, what do you think of the sources I noted above? Those are clearly about race and intelligence.--The Devil's Advocate (talk) 04:12, 14 October 2012 (UTC)

HiLo48 has decided that the hereditarian hypothesis is wrong. LMAO. And you are? — Preceding unsigned comment added by 121.67.169.53 (talk) 12:07, 14 October 2012 (UTC)

Andythegrump and Hilo are simply not interested in constructive dialogue and are only here to hinder progress. Hilo's comment is especially revealing: "To decide that certain hypotheses are just plain wrong or inappropriate is not a sign of bias. It's a sign of wisdom". No, actually it's a sign of censorship. YvelinesFrance (talk) 14:34, 14 October 2012 (UTC)

It's the job of observant and caring editors to eliminate fringe, POV garbage. We do it for many articles. That's not censorship. HiLo48 (talk) 10:16, 15 October 2012 (UTC)

The hereditarian hypothesis is not fringe and remains under discussion by mainstream psychology researchers.[7] Editors who cannot grasp this fact should be shown the door. — Preceding unsigned comment added by 211.222.107.31 (talk) 11:13, 15 October 2012 (UTC)

So according to you, Hilo, that genes have any effect whatsoever, even minuscule, on differences between individuals and between groups of people who have existed in isolation for hundreds of millennia is fringe? I'd say the purely environmental explanation is fringe and POV, hence my quote from the Economist: "Those who allowed that it might have some value (the hereditarian approach) were generally shouted down and sometimes abused, along with all others vehemently suspected of the heresy of believing that genetic differences between individuals could have a role in shaping their behavioural differences.". Give it up Hilo, the only reason you are here is for political motives. YvelinesFrance (talk) 16:26, 15 October 2012 (UTC)

Hilo, what do you think of the sources I provided and my suggested wording? I don't think there is a WP:FRINGE issue to note there is resistance to this research as such resistance is a matter of mainstream discourse.--The Devil's Advocate (talk) 17:22, 15 October 2012 (UTC)

Devil's advocate - :"Research into genetic causes for intellectual differences between racial groups is controversial and faces resistance in the scientific community due to concerns about the social implications of such research." I think the statement is generally supportable but it's unnecessarily vague on the question of both "resistance" and "research". I think the point was made earlier that it was not research into the question per se that generated difficulties but findings which support or appear to support the idea that population group differences in IQ may have a genetic determination. Conversely, findings, at least if well supported, that contradict this contention are generally not controversial for the obvious reason that they're not socially contentious and are (sort of) in harmony with wider social, cultural and political beliefs. Most papers that I've read by researchers that address this issue state that their concerns are about the misuse of research findings and hence the way that findings are presented to the public. This strikes me as a bit naive but that's irrelevant. In regard to your proposed sources, I think the two articles from the Nature debate are relevant but I'd be wary about including blogs, even high-calibre ones. The Lahm article is very interesting and it's notable the high level of support he received from his colleagues. Anyhow, I offer the following imperfect rewording: "Genetic research into population-level differences in complex traits such as intelligence can be controversial and has excited heated debate.[8] Some in the research community fear that any findings of group difference in intelligence may be inappropriately generalised as inherent to particular racial or ethnic groups and perpetuate social-stereotypes while others voice the concern that the politicization of this question may curtail important avenues of research."[9][10]

FiachraByrne (talk) 22:42, 15 October 2012 (UTC)

By the way, is anyone aware of any kind of published metric for the research output on this question?FiachraByrne (talk) 22:43, 15 October 2012 (UTC)

Those articles in Nature are definitely not blogs. Commentaries from credentialed scientists in the relevant field that are commissioned by and published in a reputable scientific journal are more than suitable as sources for material stating that there is resistance to research into this subject due to concerns about the potential implications. Presumably experts on the question of group differences in human intelligence would have some inkling as to the opposition such research can face. As to being generalized, it is the lede and thus should be a bit general, with the detail dealt with in the body and that would presumably mean the "ethics of research" section. That aside, I think your proposed wording is a decent alternative, though it could use a little polishing.--The Devil's Advocate (talk) 23:59, 15 October 2012 (UTC)

In regard to the Nature sources I referred to those as articles, not blogs. The blogs I referred to were the two other sources which you linked to above [11] [12]. These are blogs, no? FiachraByrne (talk) 00:08, 16 October 2012 (UTC)

Ok, sorry, the way you wrote it made me think you were describing the Nature articles as blogs and we were about to fight fo' real cause I'm a thug. ;)--The Devil's Advocate (talk) 00:31, 16 October 2012 (UTC)

Well it was poorly phrased and your interpretation was valid. Your formulation is succinct and supportable, I think. I retain a reservation about the use of the term resistance in the absence of some qualification. I guess I'm drawing the implication from the sentence that research is not being done because of worries about social/political reactions and possible career implications. While it seems likely that funding would be much more difficult to get for genetic research into race and IQ due to the potential controversy which could ensue I'd like to see some support for that contention from secondary sources or, failing that, for the nature of resistance to be defined in way that the sources would support. FiachraByrne (talk) 01:39, 16 October 2012 (UTC)

I was thinking "social implications" could be noted as specifically referring to the implications of findings being used by groups to support racist views. Would that suffice?--The Devil's Advocate (talk) 02:25, 16 October 2012 (UTC)

Yes I think so. FiachraByrne (talk) 12:22, 16 October 2012 (UTC)

I like the way that FiachraByrne's wording also includes the perspective of Ceci and Williams, that the scientific value of the research outweighs the social concerns. If we decide to use The Devil's Advocate's proposed wording, could we still include a mention of that? Zeromus1 (talk) 14:45, 16 October 2012 (UTC)

As far as the lede goes we would not want to have too much detail. I think the "ethics of research" section in the article could be expanded to incorporate the more minute details.--The Devil's Advocate (talk) 17:36, 16 October 2012 (UTC)

I can support FiachraByrne's suggested wording as posted above (at 22:42, 15 October) — ArtifexMayhem (talk) 20:02, 16 October 2012 (UTC)

How about this wording?:

“ Research into genetic causes for racial differences in intellectual achievement is controversial and strictly scrutinized. Many researchers fear that the findings could be used to perpetuate negative stereotypes, while others contend that this attitude inhibits legitimate scientific inquiry. ”

I think that covers everything nicely and succinctly enough for the lede.--The Devil's Advocate (talk) 22:32, 16 October 2012 (UTC)

Truthfully, I prefer my own formulation but I think your one is also acceptable. However, just to unnecessarily complicate things I'm going to offer a forth formulation (although my first - number 2 below - is probably more precise if less succinct)...

1."Research into genetic causes for intellectual differences between racial groups is controversial and faces resistance in the scientific community due to concerns about the social implications of such research."

2."Genetic research into population-level differences in complex traits such as intelligence can be controversial and has excited heated debate.[13] Some in the research community fear that any findings of group difference in intelligence may be inappropriately generalised as inherent to particular racial or ethnic groups and perpetuate social-stereotypes while others voice the concern that the politicization of this question may curtail important avenues of research."[14][15]

3."Research into genetic causes for racial differences in intellectual achievement is controversial and strictly scrutinized. Many researchers fear that the findings could be used to perpetuate negative stereotypes, while others contend that this attitude inhibits legitimate scientific inquiry"

4."Genetic research into population-level differences in intelligence can be controversial and has generated heated debate. Some researchers fear that the findings could be misused to perpetuate racial stereotypes, while others contend that the politicization of the field threatens to foreclose important avenues of research."

I think the reference to "population-level" research categories probably more accurately reflects the preferred terminology in the field. I think the distinction that this research can be rather than is controversial is somewhat important as not all such research is necessarily controversial. If can be is used closely scrutinized cannot follow. Also, most research is closely scrutinized (or, at least, it's supposed to be). I think some researchers rather than many researchers is preferable in the absence of any kind of quantification of positions in the field. I think misused is preferable to used as those who support this position generally interpret its application by political (racialist etc) groups as a misappropriation and distortion of findings. The use of the term politicization of the field more accurately reflects the fears of such researchers that political correctness/sensitivities has or could place certain research topics beyond the pale. I think that foreclose important avenues of research is better than inhibits legitimate scientific inquiry as their stated beliefs are not simply that the inquiry is legitimate but is likely to generate significant benefits (however, unlikely this actually is). It's also only slightly longer than your phrasing (No. 3) this time. Having said that I'm happy with either 2, 4 or 3 at this point and in that order. So if everyone else would like to choose we could maybe move on ...? FiachraByrne (talk) 01:29, 17 October 2012 (UTC)

It would be useful to mention that lots of researchers have turned away from the topic due to fears of harassment and ostracism. Something like this:

Research into potential genetic causes of intellectual differences between races is controversial and has generated heated debate. Some researchers fear that the findings could be misused to perpetuate racial stereotypes, while others contend that the politicization of the field threatens to foreclose important avenues of research. Scientists engaged in genetically-informed research on the topic have frequently met with condemnation and ostracism, which has had the effect of dissuading investigations of the topic.

--Victor Chmara (talk) 16:15, 18 October 2012 (UTC)

The last sentence is too slanted, but I think this suggestion would work well without that last sentence. Not too fond of the word "foreclose", but that would be simple to address.--The Devil's Advocate (talk) 17:17, 18 October 2012 (UTC)

How is it slanted? It's true and well supported by Ceci & Williams and other sources. One of the most salient facts about race and intelligence is that the few contemporary researchers who have dared to suggest that genes may have something to do with it have become academic outcasts, with the result that relatively little research on the topic gets done. The last sentence can be reworded, but the basic idea should be included in the article.--Victor Chmara (talk) 17:41, 18 October 2012 (UTC)

I agree with the Devil's Advocate: Victor's formulation is fine if the last sentence is excluded. The first sentence is quite sufficient for the lede. FiachraByrne (talk) 21:23, 18 October 2012 (UTC)

So, how would you rank it?--The Devil's Advocate (talk) 21:50, 18 October 2012 (UTC)

It's probably the best one. I'd just like someone to stick it in at this point so we could move on. If Victor wants to continue to argue for the second sentence that is, of course, fine but can we presume that we have consensus for the first one? If you want to change the word "foreclose" to something else I'm quite open to that (hamper/stifle?).FiachraByrne (talk) 23:08, 18 October 2012 (UTC)

I put it in at the end of the second paragraph of the lede. Not sure if that is the best place for it, but I don't think it should go in the first and the second paragraph was a bit shorter than the others. It could go at the end of the third paragraph if someone doesn't like it being in the second.--The Devil's Advocate (talk) 23:30, 18 October 2012 (UTC)

It's fine. I think we should leave the lede and concentrate on fixing the body of the article - build consensus for removal of tags (impossible task?).FiachraByrne (talk) 23:40, 18 October 2012 (UTC)

Causal Analysis of Academic Performance

I came across this article entitled Analysis of Academic Performance' (1977) in the journal Behavior Genetics by Rao, Morton, Elson and Yee that was cited in this review article (2009) on race and genetics by one of the authors (Morton) of the 1977 study. The findings, I think, are interesting:

Several studies have indicated that the contemporary difference in IQ between American Blacks and Whites is 15 points, without adjustments for socioeconomic class or region (e.g., Shuey, 1966). Since the tests used to define performance are highly correlated with IQ, we may take performance and IQ as equivalent. Our analysis of the Equal Educational Opportunity Survey shows that the causal effect of race is only about 15 (0.2) = 3 IQ points. This is the difference that would be expected if children were randomized among social classes, other factors remaining the same.

I was just wondering if anyone had any thoughts on the quality and relevance of this source for the race and intelligence article.FiachraByrne (talk) 23:05, 18 October 2012 (UTC)

It's already well established among mainstream psychologists that there is a significant racial gap in IQ between blacks and whites even corrected for socioeconomic status. The only controversy is the reason why this is so. I wouldn't put much faith in that single study that you've dug up.YvelinesFrance (talk) 01:42, 19 October 2012 (UTC)

In general (i.e. without a suggestion as to how it might be used) I don't see any problems with source quality or relevance. You might also find the following relevant...

Using a new data set, we demonstrate that among entering kindergartners, the black-white gap in test scores can be essentially eliminated by controlling for just a small number of observable characteristics of the children and their environment. — source

— ArtifexMayhem (talk) 04:48, 19 October 2012 (UTC)

This article shouldn't be based on single studies but rather on well-established findings supported by many studies and reported in secondary sources. The basic problem with controlling for environmental factors is that there's no evidence that you're actually controlling for causal factors.--Victor Chmara (talk) 08:16, 19 October 2012 (UTC)== Article Tags ==

This article has multiple tags - it will probably always have them given the nature of the subject matter - but would it be a plan to systematically work to remove these as far as possible?

• The Section on Brain Size has an undue weight tag
• The Section on Regression towards the mean has an undue weight tag
• The Section on Genetics of Race and Intelligence has an undue weight tag
• The Section on Evolutionary theories has an undue weight tag
• The Section on Genetic Arguments" has a neutrality disputed tag
• The Section on Validity of Race and IQ has an undue weight tag
• The Section on History of Debate has this section should be summary of main article on History of Race and Intelligence Controversy
• The Article is tagged with: does not represent a worldview; undue weight; factual accuracy disputed; neutrality disputed; unbalanced.

Are there any arguments to support, say, that the section on Regression towards the mean has been given undue weight? It consists of two sentences. The first outlines Jensen and Rushton's position. The second refutes it. Is this really undue weight?FiachraByrne (talk) 23:30, 18 October 2012 (UTC)

Well, the current history section gives way too much attention to the modern debate. We have exactly two paragraphs on the widespread eugenics research in the early 20th Century, followed by seven paragraphs about more recent research. I think trimming the latter down would get things closer to where we would want to be on that.--The Devil's Advocate (talk) 00:08, 19 October 2012 (UTC)

Agreed. As a start I'd advocate moving the section on the Pioneer Fund into the Ethics of research section. Also I'd like to put in headers for the history section to divide pre- and post-WWII. I'd probably remove/move the third and second last paragraphs as well FiachraByrne (talk) 00:24, 19 October 2012 (UTC)

I think we should keep in mind there's already a separate History of the race and intelligence controversy article. It would be best if we could minimize the amount of content we duplicate that's already in another article. Zeromus1 (talk) 01:03, 19 October 2012 (UTC)

The article is certainly in a dire state. Most of the undue tags relate to the over weight given to Rushton, Jensen, et al, scientists who have failed to build mainstream consensus for their conclusions despite decades of research. Any move to address these weight problems would be welcomed. aprock (talk) 02:25, 19 October 2012 (UTC)

Well, they can hardly be excluded, regardless of consensus, due to their importance to the debate. I think you could say - based on many statements in research papers - that the consensus amongst geneticists is that racial difference in IQ is not accounted for by genetics.

In regard to Jensen, although it's a pretty crude measure, we could weight the relative importance of his articles at least based upon how often they've been cited. So, using Scopus (author search for Jensen, Arthur and searched within results for race and intellligence), the following are his top cited articles and therefore the ones which should be given greatest weight:

• Thirty Years of Research on Race Differences in Cognitive Ability (2005) 108 Cites
• Race, Social Class and Ability Patterns on the WISC-R (1982) 35 Cites
• Race and Sex Difference in Head Size and IQ (1994) 26 Cites
• Forward and Backward Digit Span Interaction with Race and IQ: Predictions from Jensen's Theory (1975) 19 Cites
• Occupation and Income Related to Psychometric G (2001) 15 Cites
• The Totality of Available Evidence Shows the Race IQ Still Remains (2006) 13 Cites
• African-White IQ Differences from Zimbabwe on the Wechsler Intelligence Scale for Children-Revised are mainly on the G Factor (2003) 11 cites
• Comments on Correlations of IQ with Skin Color and Geographic-Demographic Variables (2006) 9 Cites
• Wanted: More Race Realism, Less Moralistic Fallacy (2005) 9 Cites
• James Watson's Most Inconvenient Truth: Race Realism and the Moralistic Fallacy (2008) 8 Cites
• Adoption Data and Two G Related Hypotheses (1997) 8 Cites
• An Examination of Culture Bias in the Wonderlic Test (1977) 6 Cites

• The Theory of Intelligence and its Measurement (2011) 4 Cites
• Do Age-Group Differences on Mental Tests Imitate Racial Differences (2003) 3 Cites

According to Scopus, the remainder of his articles receive 0 cites. Obviously, there are some historical articles that are not returned which should probably be included. Also, one should weigh these results in terms of the recency of publication as 2011 article has had less time to accumulate citations than an article from 1974. FiachraByrne (talk) 09:08, 19 October 2012 (UTC)

Those citation numbers are not even remotely plausible. Check out Google Scholar, each of those has been cited many more times. "How Much Can We Boost..." probably has more citations than any other article in the history of IQ research. His books, especially Bias in Mental Testing and The g Factor, are also some of the most frequently cited monographs in the history of the discipline. The latter, in particular, is the sine qua non of contemporary research on cognitive abilities, and is cited numerous times in each issue of various specialist journals.

There is zero evidence for the claim that "the consensus amongst geneticists is that racial difference in IQ is not accounted for by genetics." Moreover, the question is not strictly in the purview of geneticists per se, but rather psychometricians and behavior geneticists (who may not be geneticists by training). It's difficult to establish what the mainstream view on the causes of racial differences is because it's such a taboo subject. The best evidence we have is from the anonymous 1980s survey of hundreds of behavioral scientists by Snyderman and Rothman. It showed that the modal view of experts on just about all questions was the same as Jensen's. For example, only 15% said that the black-white IQ gap was entirely due to non-genetic factors, whereas 45% said that both genetic and non-genetic factors are involved. The 1994 Mainstream Science on Intelligence statement, signed by 52 experts, is also completely in line with Jensen's views. There is no reason to believe that the views of experts on this topic have radically changed since the 1980s and 1990s.

The best answer we have is that currently there is no consensus on the causes of racial disparities in IQ (cf. Intelligence: Knowns and Unknowns). In this article, we should present all prominent viewpoints and arguments that have been published in reliable sources. Those include the views of hereditarians like Jensen and Rushton as well as those of their opponents.--Victor Chmara (talk) 09:45, 19 October 2012 (UTC)

Google Scholar is not an appropriate source to track citations. No plausible published study would use it as a metric. I'm looking specifically at articles not at books as these would require a different measurement instrument. I've also explicitly stated that this may not be only database from which to draw citations - although I'd struggle to think of a better one for this field. The statement that there is a consensus amongst geneticists that the IQ gap is not attributable to genetic differences between races is derived from review articles/op ed. pieces that make that contention such as the Ceci and Williams article - there are more and you could argue that there doing that to insulate the field from critique. Obviously, such a statement would need more support and would not necessarily apply to different disciplines. The 1980 survey you refer is too old to hold any contemporary relevance and likewise with the statement on 'mainstream science' from the early 1990s. They are historically relevant but that's it. It would be better to cite a recent review article giving an overview of the field and positions within it. FiachraByrne (talk) 10:39, 19 October 2012 (UTC)

Based on the Scopus database (and there may be more relevant databases), a search for race and intelligence in all fields returns 14,130 articles. Limiting these results to review articles with key words for race and intelligence returned 203 articles. Based on a reading of article abstracts, not all of these were directly relevant (articles on anti-social behaviour, etc). So based on citations, the most relevant articles are:

• Racial and ethnic stratification in educational achievement and attainment (2003) 188 Citations

• Personality psychology: Current state and future prospects | [Persönlichkeitspsychologie: Stand und perspektiven] (2005) 5 cites (not sure of relevance to race)

These results are obviously imperfect. First, they should really be broken up by discipline. Further, not every article included really meets the criteria of a review article. Textbooks should also be included - we just need a plausible system to weigh their relative influence. I think the idea of using some kind of metric is sound, however, as opinions on this topic are extremely subjective. FiachraByrne (talk) 10:45, 19 October 2012 (UTC)

I should state that the Scopus database only goes back to 1973, ... incorrect, but not sure why earlier articles for Jensen were not showing up ... hence my observation that we'd also have to include some historical articles. FiachraByrne (talk) 10:55, 19 October 2012 (UTC)

What you say about Google Scholar is not true. Quoting from the Wiki article: Some searchers consider Google Scholar of comparable quality and utility to commercial databases.[16][17] The reviews recognize that its "cited by" feature in particular poses serious competition to Scopus and ISI Web of Knowledge, although, in a study limited to the biomedical field, the citation information found in Google Scholar have found to be sometimes inadequate, and less often updated.[18] Your limitation to articles is also arbitrary, because lots of research on race & IQ is published in multiple-author books and monographs. Scopus appears to be rather unreliable. For example, it reports six citations for "Personality and Scholastic Achievement in Three Ethnic Groups", but Google Scholar reports 20, most of them articles. Moreover, the Scopus list does not include some of Jensen's most important and highly cited articles, such as his 1982 Behavioral and Brain Sciences target article on Spearman's hypothesis. In short, Scopus is not reliable here and even if it were, citation counts are not the way to judge what sources are relevant in Wikipedia.

Your argument that a survey from 1984 and a consensus statement from 1994 are only of historical interest makes no sense. Both and especially the 1994 statement are frequently cited in newer research. If you were right, then surely the 1996 APA report, the 1994 AAA statement, and the 1996 AAPA statement, all prominently cited in the article, are also outdated. The idea that sources have some clear expiration dates leads to absurdity.

Ceci and Williams's self-serving claims about consensus are unsupported by anything other than their own words. There are other recent sources, such as Earl Hunt's new textbook Human Intelligence (2011), which hold that the causes of the racial gaps are currently unknown and that strong claims in either direction are not supported by evidence.--Victor Chmara (talk) 11:29, 19 October 2012 (UTC)

The limitation to articles is based upon what is searchable through Scopus. I didn't imply that books should be excluded, just that I wasn't sure what metric to use to weigh them. The purpose of the citation index is to get a feel for the actual distribution of influence and the relative weight of sources in the field. It might be a useful guide but it would not be a solely determining instrument for an article's inclusion or exclusion. Some of your points on Google Scholar are valid. It returns a reasonable result of an individual author. Trying to search for sources through key words is another matter. In the latter instance, it becomes unworkable. Thus, if I search for "race AND intelligence" it returns 759,000 results. Now, this is many more results than Scopus or an equivalent database would provide but they are ranked based upon the frequency of the appearance of those terms in the title or text rather than on citations or some other measure. Nor can I do much to order those search returns. It would take days to go through it whereas I can establish a similar result through Scopus in minutes. Scopus may return less results but I can be reasonably confident that recent work in established journals will be returned. Now, it may then be feasible to turn to Google Scholar and search for individual items or authors but I'd suggest that we use Scopus or Web of Science first. Scopus is widely used in Academia even if it imperfect. I don't think it's plausible to say its unreliable. The use of citation counts is relevant because it's the only way to arbitrate the 'undue' tags that have proliferated throughout the article.

Ceci and William's statement may not be true and it may be self-serving. I don't know. I do know that we're using their other statements to support contentions in the lede. I also think they have a reasonable claim to speak for their field in op-ed piece. However, if such a statement were to be inserted it would need support from other sources. FiachraByrne (talk) 12:35, 19 October 2012 (UTC)

Ceci and Williams's claim about "an emerging consensus" is self-serving, unverifiable, and contradicted by other sources, but their other arguments do not suffer from such limitations. Establishing what the scientific consensus is in a field where expressing certain viewpoints leads to public condemnation, academic ostracism, and, in some countries, police investigations, is obviously a tricky matter. Snyderman and Rothman's survey showed that the views of scientists, when surveyed anonymously, on controversial topics are often at great variance with what the media and individual scientists consider to be the mainstream view.

There is a Wikipedia guideline on identifying reliable sources, so there's no legitimate rationale for coming up with standards for reliable sources that apply only to this article. A good way of finding relevant sources is to look at prominent books and reviews that deal with race and intelligence. For example, there are very few accounts that do not give a prominent place to Arthur Jensen's views.--Victor Chmara (talk) 13:09, 19 October 2012 (UTC)

As I've previously said the validity of the Ceci and Williams claim would depend on the addition of other sources.

As to the other matter, it's not issue of whether sources are reliable but as to whether they've been given undue prominence. I'm suggesting that we could use a citation index to help us determine that. FiachraByrne (talk) 15:11, 19 October 2012 (UTC)

I think we also should look into whether this article gives undue prominence to Richard Nisbett. Google scholar shows 160 citations to Intelligence and How to Get It, while The g Factor is cited 2,181 times. Yet in this article there are 13 citations to Nisbett's book, and only three citations to The g Factor. I haven't examined Scopus, but based on Google scholar Nisbett's book seems to be given far more weight than it should. Zeromus1 (talk) 15:44, 19 October 2012 (UTC)

I think that that is supportable. Bear in mind, however, that Nisbett's article was only published in 2009 - therefore it's averaging 40 citations a year and is highly cited. Jensen's article is averaging 145 citations, however. That doesn’t mean Jensen’s article is supported and this is a crude measure, etc, but Jensen's publication is obviously important to the topic even if a lot of those citations are criticisms. But I'd like to get an overview of the field first. Also, what I’d really like to identify is a highly cited review publication or textbook that addresses the issue of race and intelligence.

I got a piece of free software called Publish or Perish which makes the Google Scholar results sortable etc. The other thing I've been wondering is what kind of weight we can give to Google Scholar's ranking? Does it provide a better result than simple citation counting. There's a decent evaluation of its ranking algorithm here if anyone's interested. It obviously over-rates publication titles rather than text for searches. There are lists below of some searches I did through Google Scholar that were sorted using Publish or Perish. Some of these publications or more or less relevant and I’m not suggesting that all of these publications or that only these publications should be included. It’s just an indication of some important publications that address the subject. Now doing a basic search for Race AND IQ through Google Scholar we get the following results:

For the discipline of psychology at least, the text to get would appear to be Robert J. Gregory's Psychological Testing: History, Principles and Applications (2010).FiachraByrne (talk) 21:44, 19 October 2012 (UTC)

We've clearly fallen into the POV pushing train here. The expressed sentiment appears to be that the views of Rushton and Jensen should be elevated even further, and this sentiment is being pushed by what appears to be original research and over-reliance on primary sources. If people are serious about contributing to this article, they are going to have to put away primary sources pick up some tertiary sources, like textbooks and external reviews, to get an understanding of the mainstream view of this topic. aprock (talk) 23:33, 19 October 2012 (UTC)

I'm not sure how you've come to those conclusions regarding POV pushing or original research. The attempt is to address in some kind of objective manner the undue tags that have been added to the article. If you look at the citation results from Scopus I've identified review articles and, as I haven't cherry picked them, they reflect a diversity of views. I can't select research articles or textbooks in a simple non-labour intensive manner with Google Scholar but in the post just above yours I've identified what I think is the single tertiary source that appears in the top 20 (based on total citations and citations per year) for those results. Now, it's a text book about psychological testing so, without having access to it at this point, I presume that it at least supports the validity of IQ tests. But I've highlighted the text not because it reflects my POV (it doesn't if that matters) but because it is a highly cited textbook that addresses race and IQ. Therefore, it should be a suitable source for the perspective of that discipline. I haven't doctored the results to reflect mine or any other point of view and, again, if you actually look through the Google ones I don't believe Rushton appears at all. FiachraByrne (talk) 00:00, 20 October 2012 (UTC)

As interesting as your research on Scopus has been, it is precisely original research and cannot be any kind of basis for determining which primary sources to cite. aprock (talk) 03:09, 20 October 2012 (UTC)

Whereas your personal opinion is. — Preceding unsigned comment added by 115.92.159.73 (talk) 11:10, 20 October 2012 (UTC)

My personal opinion is that James Flynn is probably the most reliable commentator on this topic ... but who cares? I have no expertise on this issue.

The writing of any article in WP depends upon researching good sources. The number of citation returns can be used to identify publications which are widely cited in the field thus indicating their importance, relevance and reliability in the field. Scopus and Google Scholar have been used to identify: 1) the citation returns for a single scholar - (Jensen using Scopus); review literature for the topic (using Scopus); and the most highly cited or ranked (according to Google) publications in the field (using Google Scholar). From the Google Scholar search I've identified a single tertiary source that is not currently used in the article but it would be quite possible to identify more by examining more returns. The Scopus returns identify many more secondary and tertiary sources. If I'm not mistaken this is what you were calling for yourself in previous posts? The citation returns from the Scopus or Google Scholar database searches are not themselves going to be included in the article so I don't see how WP:NOR is relevant. The initial impetus to investigate citations was to explore to what degree WP:UNDUE applied to certain tagged sections of the article. The policy on WP:UNDUE states, "Neutrality requires that each article or other page in the mainspace fairly represents all significant viewpoints that have been published by reliable sources, in proportion to the prominence of each viewpoint". The methods it advocates to establish the proportional prominence of a given viewpoint are decidedly impressionistic but that would probably be sufficient in most scenarios. However, I'm attempting to introduce an objective measure to assist, but not determine, the relative weight that should be given to the primary, secondary and tertiary sources for the article. FiachraByrne (talk) 13:19, 20 October 2012 (UTC)

Ultimately, any improvements we make to the article will have to be made one at a time. Rather than attempt to fix the entire article at once, I think it would be best to focus on specific steps we can take to incrementally make it better.

Are we agreed that this article gives undue prominence to Nisbett's Intelligence and How to Get It? It is the article's most cited source. It's cited more than the 1996 report from the APA, and more than any textbook. Intelligence and How to Get It is not actually the most prominent source that exists about race and intelligence, but this article treats it as though it were.

A few months ago, ArtifexMayhem went through the article and removed a lot of the material cited to Jensen that he viewed as excessive. I suggest that the same thing should now also be done for some of the excessive Nisbett material. Zeromus1 (talk) 22:23, 20 October 2012 (UTC)

In my opinion, we need good, highly cited secondary or, ideally, tertiary level sources for each of the relevant disciplines who have approached this research question (sociology, psychology, genetics, etc). We should then use these sources to frame the positions by discipline in each section and then drill down to primary sources to make sure that there's good coverage of all major viewpoints, arguments and rebuttals. I'm not sure the edits by ArtifexMayhem improved the article nor am I convinced, even if the presence of his 2009 publication is excessive, that editing out Nesbitt's points will necessarily improve the article either. Additionally, you appear to be advocating tit-for-tat editing which is not conducive to establishing any kind of consensus.

Anyhow, as I said citation counts, used on their own, are a crude measure. Bear in mind also that most of the citations removed were to Rushton and Jensen's 2010 article, which is hardly their most cited. Obviously more recent material won't have had the opportunity to get as many citations (and that Google counts everything) and recent articles & publications will have more up-to-date arguments and analysis of data and so, provided the primary research has had a chance to make it into the secondary literature, it should be treated more favourably. Going on citation counts alone it seems that Rushton and Jensen's 2010 article was over-cited and probably still is - but you'd have to look at the content of the article, the quality of sources which cite it, what disciplines they are in, how often the publication's authors are in fact citing it and what those sources say about it [16]. Equally, you'd have to do the same for Nisbett's 2009 article [17]. Having said that I'm not hugely in favour of removing content and citation counts should just be a guide to the use of sources. Also, overall I'd have to say that Jensen, pivotal as he is to the whole question, has pretty good coverage in terms of breadth and depth.

Nisbett has two publications cited.

FiachraByrne (talk) 00:31, 21 October 2012 (UTC)

I suggested cutting out some of the Nisbett material just because looking at the article history, that appears to be the cleanest way to solve the problem of undue weight. When the Jensen material was removed, Victor Chmara reverted the removal once and then his revert was undone, but as far as I can see it never was brought up on the talk page. If we could do the same thing with Nisbett, that would be an easy way to solve the undue weight problem for him also.

The reason I'm unsure about your suggestion is because I'm not sure it's realistic we'll able to take a top-down approach and rewrite the whole article. It likely will take at least a month, and who knows what might change in that time? The Devil's Advocate helped a lot with reaching a consensus about the lead, but now there's a discussion at WP:AE about possibly indef blocking him. In my user talk, Victor Chmara said that he usually stays away from this article, and I'm not confident I'll still be around in a month either. Are you confident you'll be around for long enough for your approach to bring real improvements to the article? Zeromus1 (talk) 01:49, 21 October 2012 (UTC)

FiachraByrne, I could not agree more. High quality secondary sources are key. Where did you want to start? — ArtifexMayhem (talk) 04:55, 21 October 2012 (UTC)

Well, I'm a little perturbed by how easy it appears for some users who work on this page to be sanctioned so I might review my participation here. Also, I've several deadlines for the next few days so I won't be posting so regularly, probably. Incidentally Zerosmus1 I left a comment on the discussion at WP:AE, for what it's worth, of my own limited experience of working with TDA on this page. I can't really advocate editing on the basis of when people may become blocked or banned, however. FiachraByrne (talk) 22:38, 21 October 2012 (UTC)

Anyhow, as an immediate issue I think a fair point is raised that Nisbett's 2009 publication, while useful in addressing many of the issues, is over-represented as a source. Therefore, it would seem logical to replace some of those citations with 3rd-party-authored quality secondary sources that discuss Nisbett's findings. Due to the recency of Nisbett's book there aren't going to be that many that discuss the aspects of his text that deal specifically with race and IQ, unfortunately (63 mention race and IQ all told). As an aside, is it reasonable, if not ideal, to treat the literature review section (and only that) of primary research articles as secondary sources? Perhaps if we just agreed to follow WP:MEDRS so far as possible it might facilitate things. Anyhow, there have been about 160 citations of Nisbett's 2009 book and 63 mention race and IQ. I've been through a few of these and thus far the best I can find is this one which may be adequate for some points but is far from ideal. Are the arguments which Nisbett presents in his 2009 publication and which are contained in this WP article novel to the 2009 publication or has he published most of these points before and therefore could other secondary sources be used? Longer term I'd like to identify a few, reliable 3rd-party-authored secondary sources for each of the relevant disciplines that review the literature in some kind of systematic way and that present the arguments of the various proponents fairly. FiachraByrne (talk) 22:28, 21 October 2012 (UTC)

FiachraByrne, the paper you linked to appears to be about brain size. I can't tell whether it's a secondary source, but if it is it would be a good source to cite in the article's "Brain size" section. However, that section actually is not one of the sections that cites Nisbett, so I don't think it will be helpful for reducing the undue weight given to him.

I recently put some time into reviewing this article's citations to Intelligence and How to Get It, and also the history of the Jensen material that has been removed, to make some suggestions about how to solve this problem. The article currently has 13 citations to Nisbett's book. Here is my opinion about what to do with each of them:

1: "Richard Nisbett, another psychologist who had also commented at the time, later included an amplified version of his critique as part of the book Intelligence and How to Get It: Why Schools and Cultures Count (2009)." It's reasonable for a history of the debate to include a mention of Nisbett, so I don't think this should be removed.

2. "The African American population of the United States is statistically more likely to be exposed to many detrimental environmental factors such as poorer neighborhoods, schools, nutrition, and prenatal and postnatal health care." This sentence has two sources, Nisbett 2009 and Cooper 2006. The Cooper source is adequate to support the sentence, so I think the Nisbett source can be removed as redundant.

3. "Nisbett argues cultural traditions valuing education can explain the high results in the US for Ashkenazi Jews (Talmud scholarship) and East Asians (Confucianism and the Imperial examination system)." This entire sentence (Cultural traditions valuing education) is just one sentence, cited entirely to Nisbett. I'm not convinced Nisbett's point is separate from the point made by the "Education", "Logographic writing system" and "Caste-like minorities" sections. If there are sources besides Nisbett that discuss cultural traditions valuing education outside of these other topics, then this section should be expanded using these sources, but I don't believe a one-sentence section cited only to Nisbett should stay in the article.

4. "A number of scientists, supported by the American Anthropological Association, reject any genetic contribution to racial IQ gaps." This sentence is part of a paragraph that's a back-and-forth between Jensen, Rushton, Nisbett, Herrnstein and Murray. I don't see the point of it besides giving more undue weight to all of these authors. I suggest getting rid of the whole paragraph.

5. "On the other hand, cultural psychologist Richard Nisbett has argued that "(t)here are a hundred ways that a genetic difference in intelligence could have arisen – either in favor of whites or in favor of blacks."" This sentence is contrasting Nisbett's viewpoint with Brace's, so we shouldn't remove one without removing the other. I'd be okay with replacing Nisbett with another source, or leaving this part alone for now.

6. "Dickens and Flynn argue that the conventional interpretation ignores the role of feedback between factors, such as those with a small initial IQ advantage, genetic or environmental, seeking out more stimulating environments which will gradually greatly increase their advantage, which, as one consequence in their alternative model, would mean that the "heritability" figure is only in part due to direct effects of genotype on IQ." This is cited to Hunt & Carlson and to Flynn & Dickens as well as to Nisbett. The other sources are more than adequate, so as with #2 I think the Nisbett citation can be removed as redundant.

7-9: The "racial admixture studies" section has several citations to Nisbett. These were originally part of a back-and-forth between Nisbett and Jensen, in which the Jensen material was later removed. I don't see the sense in this removal. Why did they also remove Mackenzie, which was a high-quality secondary source? I'm reluctant to remove the Nisbett material in this section because it offers a lot of detail that isn't in other sources (as far as I know), but I also don't think a single sentence cited to Jensen in three paragraphs of text was undue. It might be best to just change this section back to the way it was before the removal.

10 & 11: The "Mental chronometry" section has another back-and-forth between Jensen and Nisbett. I suggest removing most of the Jensen and Nisbett material (especially in the section's second paragraph), and replacing it with a secondary source such as Hunt (2011).

12 & 13: The "Policy relevance" section has two citations to Nisbett, and they are redundant with one another. It cites Nisbett for each of two sentences of the same paragraph, both of which are to say he thinks interventions should be better researched. I think we only need one of the two.

If other people agree with this proposal, The number of citations to Intelligence and How to Get It will be reduced from thirteen to six or seven, which seems more consistent with that book's amount of prominence. My proposal also will slightly reduce the number of citations to Jensen and Rushton, which might be valuable if the article has an undue weight problem for them also. What do others think about my proposal? Zeromus1 (talk) 09:04, 22 October 2012 (UTC)

Yes, as I said the source was far from ideal. I haven't had time to go through them all systematically. Superficially at least I think most of your suggestions are fine but, personally, I can agree until I've had time to read through the specific sections of the article that would be effected. I won't be able to do this for a couple of days, I'm afraid. FiachraByrne (talk) 01:45, 23 October 2012 (UTC)

I'm going to say no to #2. The only relevant quote in Cooper's paper is: 'Abundant historical and social science data exist to demonstrate the impact of skin color gradients as a marker of social status. What Rowe would apparently like to do is dismiss the role of institutionalized racism in shaping the structural determinants of success in U.S. society, like the job, housing, and educational markets'. I don't think Cooper adequately supports the statement that, "The African American population of the United States is statistically more likely to be exposed to many detrimental environmental factors such as poorer neighborhoods, schools, nutrition, and prenatal and postnatal health care." He mentions lower birth rate weight but doesn't state explicitly that it has anything to do with prenatal care (although he clearly believes it's caused by social determinants). He supports much of the meaning of the first part of the sentence, 'more likely to be exposed to many detrimental environmental factors' but little else. If we're to replace Nisbett in this instance we'd need a better source for this statement. FiachraByrne (talk) 00:37, 24 October 2012 (UTC)

The brain size topic already has it's own article. I would suggest updating that article appropriately, then applying the appropriate wp:summary style here. Adding new information here without first adding it to the main articles for that topic would not make sense. aprock (talk) 02:55, 24 October 2012 (UTC)

FiachraByrne, thanks for noticing that sourcing issue. What do you recommend? I can't think offhand of any high-quality secondary sources that go into as much detail about #2 as Nisbett does, but that doesn't mean they don't exist. If you know of one, we could replace the second Nisbett citation with it. Or we could change that sentence to say "more likely to be exposed to many detrimental environmental factors", and cite it to just Cooper. Either option would be fine with me.

Also, can you give an opinion about the rest of the changes I proposed? Zeromus1 (talk) 04:03, 24 October 2012 (UTC)

I'm just going through them as I have time. For the moment I'd be inclined to leave #2 but I don't imagine it should be so difficult to get another source to support that statement. FiachraByrne (talk) 08:24, 24 October 2012 (UTC)

I agree with #3. I can't find sources that would allow for an expansion of that section. If anyone else can, please chip in. FiachraByrne (talk) 23:00, 26 October 2012 (UTC)

It looks like there's consensus to remove this section so removing this now. BlackHades (talk) 12:44, 1 February 2013 (UTC)

No. 4. I guess you could drop Nesbitt from this but I would have thought the genetic contribution to any putative difference in IQ between "racial groups" is kind of key to the whole argument? edit - perhaps use the Hunt evaluation of Jensen's and Rushton's estimate quoted by Aprock below? FiachraByrne (talk) 03:25, 27 October 2012 (UTC)

No. 6. I haven't checked the other sources, but if what you say is true Nisbett can be removed from this.

Nos 7-9. I'd more or less return that section to the way that it was previously. I think the editing of sources to remove some sections was highly selective.FiachraByrne (talk) 03:23, 27 October 2012 (UTC)

Nos 10 & 11. I don't have Hunt's book so I'd like to hear Aprock's and Victor's opinion of this proposal.FiachraByrne (talk) 03:28, 27 October 2012 (UTC)

Nos 12 & 13. Agree - but I'd be inclined to rewrite that whole section. FiachraByrne (talk) 03:30, 27 October 2012 (UTC)

I'm glad you agree with me about most of these, but I'm not sure you understand what I'm suggesting in #4. I'm suggesting getting rid of that whole paragraph, not just the part cited to Nisbett. "A number of scientists, supported by the American Anthropological Association, reject any genetic contribution to racial IQ gaps. The American Psychological Association, while maintaining the causes of the gap are presently unknown, stated that "what little [direct evidence] there is fails to support the genetic hypothesis." Jensen & Rushton and Herrnstein & Murray, however, argue that there is a substantial (50–80% in the US according to Rushton and Jensen) genetic contribution to the black-white IQ gap."

What does this paragraph accomplish? It's just rehashing what the rest of the article says about the viewpoints of these groups and researchers. I don't approve of how it says "a number of scientists" when citing Nisbett, Mountain & Risch, but lists the four hereditarian researchers by name. It would be more neutral to say "Nisbett, Mountain and Risch" instead of "A number of scientists". This paragraph also gives undue weight to Nisbett, Jensen and Rushton, while ignoring the views of researchers like Loehlin and Hunt who take intermediate or agnostic positions. Because this whole paragraph has so many problems, and appears to add nothing of value to the article, I'm suggesting the paragraph should be removed. Zeromus1 (talk) 01:33, 28 October 2012 (UTC)

Well, I'd regard that section as a secondary lede which should/could be used to summarise the broad positions within the field. The reason, I presume, behind referring to "A number of scientists" in the first section and naming individual researchers in the second is that the first is a mainstream stance and the second is not. I think it provides a good precis of positions prior to the more in-depth treatment which follows and also distinguishes between general positions held by bodies associated with particular disciplines and the position of individual researchers who are not mainstream. To argue for or against the phrase 'a number of scientists' you'd have to construct an argument as to whether or not it's a mainstream position in the sciences generally. Likewise with the naming of Jensen & Rushton. FiachraByrne (talk) 13:50, 28 October 2012 (UTC)

I don't think either the hereditarian position or the 100% environmental position is mainstream. Victor Chmara made the point below that mainstream sources such as Earl Hunt most often take an agnostic viewpoint that rejects both of the extreme positions. Hunt's book also summarizes the positions of Jensen, Rushton and Nisbett, so this paragraph could be replaced with a summary from him. There seems to be a consensus that Hunt is a reliable mainstream source that this article should use more of, so maybe replacing the primary sources in that paragraph with Hunt's summary would be the best option. What do you think of that suggestion? Zeromus1 (talk) 20:40, 28 October 2012 (UTC)

I'm not sure I understand the objections to Nisbett as a source. The current problem with the article is the undue weight given to Rushton and Jensen, to the great exclusion of more mainstream researchers. aprock (talk) 14:11, 24 October 2012 (UTC)

Aprock, contrary to what you seem to think, "mainstream" does not mean "people who agree with me." Nisbett is a social psychologist who has never done original research on intelligence. He has never published a single article in specialist differential psychology journals. He has published a few polemical accounts of the race and intelligence issue, and is certainly not a mainstream intelligence researcher, or an expert on intelligence at all. In contrast, Jensen is about as mainstream as it gets. For example, his The g Factor is the bible of contemporary psychometric intelligence research, cited more frequently than any other work in the field. Rushton, too, was widely published in specialist journals, and, IIRC, sat on the editorial boards of Intelligence and Personality and Individual Differences. Non-mainstream researchers do not have such credentials.

The problem with this article is that some people want to exclude certain arguments and certain lines of evidence even though they are reported in reliable sources. Ideally, this article would give an impartial account of all the relevant evidence and all the various arguments and counter-arguments that researchers with different perspectives have put forth. Inevitably, Jensen and his coauthors are going to feature prominently in a neutrally written article, because race and intelligence as a topic of scientific research exists today largely because of Jensen's work. For example, it's bizarre to suggest that Nisbett's views should have a prominent place in the article but not Jensen's, considering that most of Nisbett's work on this topic is explicitly about countering Jensen's arguments.--Victor Chmara (talk) 15:16, 24 October 2012 (UTC)

Aprock, contrary to what you seem to think, "mainstream" does not mean "people who agree with me." If you're going to preface your remarks with a gross assumption of bad faith, do you really think anyone is going to take you seriously? I suggest you strike that remark. aprock (talk) 02:27, 25 October 2012 (UTC)

When you're claiming that someone is or isn't mainstream, you're expected to back up the claim with sources. Otherwise it's just your personal opinion. Of course, this is far from the first time you've attempted to have Jensen or others written off in a similarly cavalier way.--Victor Chmara (talk) 07:35, 25 October 2012 (UTC)

The fact that Rushton and Jensen's conclusions are not in the mainstream is not a personal opinion. The status of their research done by Rushton and Jensen has been hashed over multiple times on the talk pages here. The most relevant place to review would be [18] and [19]. To date, there is no direct evidence or even a proposed mechanism which suggest that the achievement gap among races is due to genetics. If you review tertiary sources like Hunt's Human Intelligenc, he is quite clear about the validity of their conclusions:

The 80% default hypothesis [of genetic contribution to racial differences poposed by Rushton, Jensen, and Lynn] is an extreme and excessively precise statement. It is based on the assumption that factors that contribute to the between-group differences are the same factors that contribute to within-group differences. This is doubtful... The evidence required to quantify the relative differences is lacking.[pg 434] The argument for genetic differences has been carried forward largely by circumstantial evidence.[pg 447].

You'll find similar assessments from any other mainstream tertiary source. See also chapter 15 of The Cambridge Handbook of Intelligence. aprock (talk) 19:56, 25 October 2012 (UTC)

The status of the hereditarian view has indeed been hashed over many times, and never has anyone been able to demonstrate that it does not deserve a prominent place in this article. The attempt to marginalize the views of people like Jensen contravenes WP:NPOV, because Jensen is very prominently featured in reliable sources. Hunt, for example, while not endorsing Jensen's "default hypothesis", discusses Jensen's views at length, and also rejects Nisbett's views ("Nisbett's extreme statement has virtually no chance of being true"). Hunt explicitly refuses to endorse either of the "extreme" hypotheses about the causes of racial differences, which is what we should do in this article, too. Hunt's concluding chapter in the The Cambridge Handbook also gives a thorough trashing to the sort of obscurantist views presented by Daley (who?) and Onwuegbuzie (who?) in their chapter in the book.--Victor Chmara (talk) 16:12, 26 October 2012 (UTC)

No one has said Rushton and Jensen (and Lynn) do not deserve a prominent place. What has been said, and the reason for the tags, is that the current weight given to their research, and their out of the mainstream conclusions, is undue. Regarding Hunt, I certainly agree that it is a high quality tertiary source reflective of mainstream consensus. And a source which the article should broadly reflect. The extensive hashing over primary sources (as has been occurring above) ahead of tertiary and secondary sources is precisely what need avoid. aprock (talk) 16:55, 26 October 2012 (UTC)

Well, if there's agreement on the use of Hunt as a good secondary source and you both have access to this source can we use it to replace some of the primary sources in the article? There is, I think Aprock, a problem with the overuse of Nisbett's 2009 book which also needs to be addressed. FiachraByrne (talk) 22:46, 26 October 2012 (UTC)

Aprock, you seem to be under the assumption that I want to add more primary sources, or that I want to increase the amount of weight given to Jensen and Rushton, but I haven't proposed either of those. I've proposed to add back one Jensen citation that was removed earlier, and also to remove two others currently in the article, so the overall effect will be to slightly reduce the number of citations to Jensen. I'm also proposing to add back one secondary source (Mackenzie) that was removed without a good reason, and to reduce the amount of weight given to Nisbett. If you think the article gives undue weight to Jensen and Rushton, it certainly gives undue weight to Nisbett also. Addressing the problem of undue weight to Nisbett doesn't have to mean we have to deny there's a problem with undue weight to Jensen. All it means is that we're addressing the Nisbett problem first, because Intelligence and How to Get It currently is the article's most cited source, and it shouldn't be.

Also, I agree with everyone else that Hunt is a good mainstream secondary source. I've already proposed that the Jensen and Nisbett exchange in the Mental Chronometry section be replaced with a summary from Hunt, and I'm open to similar proposals for some of the other sections. Zeromus1 (talk) 22:55, 26 October 2012 (UTC)

The only arguments against Nisbett I've really seen on this talk page are based on google scholar, which cannot be used to establish due weight. Given that it's a relatively recent tertiary source by a well respected scientist published for a lay audience, it's hard to see how it is out of place here. That said, it's certainly the case that we should also incorporate other tertiary sources like Hunt and Daley, while reducing reliance on many of the primary sources in the article. aprock (talk) 03:39, 27 October 2012 (UTC)

Well, Victor has a few points but no-one can really argue that Nisbett is an unreliable source. I'm not so sure that he's so central to the field that he should be the preeminent authority in the article. Also, I think it would be better if the article leant more towards 3rd party secondary sources rather than those most central to the dispute. If nothing else, as with the Hunt example above, there'd be a much better chance of achieving consensus. Plus, you'd have to look at the actual nature of Zeromus's suggestions which are, I think, pretty fair all in all. As regards Google Scholar, well, it's just an indication (and only an indication) of how relevant the scholarly field thinks a given publication is. But you'd have to drill down into the actual citations to establish that. And, of course, you'd have to look at the quality and nature of the publication. Good systematic reviews in secondary sources by otherwise non-interested and authoritative parties in each of the relevant disciplines would be ideal. FiachraByrne (talk) 19:27, 27 October 2012 (UTC)

Nisbett's oversized footprint here is attributable in no small measure to the impact of at least one on/off again topically banned user editing under two disclosed accounts who may have earnestly believed Nisbett provided "balance". That's because, in my estimation, his conception of how this article should be constructed is along the lines of "Jensen/Rushton say" and that he might pretend "NPOV'd" by a kind of "go through the motions" after-shave, or platitude, "What Jensen/Rushton say is not so." And Nisbett had a neat and tidy Rushton/Jensen "rebut" in a teensy appendix in his book that was overly cited to satisfy this fake-do NPOV. And thus Nisbett got cited to death about what he thought about Rushton/Jensen's ideas (which were in his appendix!) Nisbett's not an unreliable source. He may be a ridiculously overused source, but that's only because so are Jensen and Rushton. Jensen and Rushton do not demarcate this topic. Professor marginalia (talk) 08:13, 30 October 2012 (UTC)

Lack of post-adolescence follow up in Moore, Eyferth, and Tizard studies

Under "Uniform rearing conditions" I added the following line regarding the Moore, Eyferth, and Tizard studies. "However unlike the Minnesota Transracial Adoption Study, these tests did not retest the children post-adolescence when heritability of IQ would be much higher."

This is an important fact to mention as heritability of IQ is somewhat low pre-adolescence but very high post-adolescence as mentioned earlier in the article under "Heritability within and between groups" which states "It has been argued that intelligence is substantially heritable within populations, with 30–50% of variance in IQ scores in early childhood being attributable to genetic factors in analyzed US populations, increasing to 75–80% by late adolescence."

Aprock reverts my edit saying "not in cited source". Although he doesn't make it clear what exactly he's objecting. But everything in the line I added can be confirmed by sources that are already cited in this article. The argument that heritability of IQ is higher post adolescence is already mentioned earlier in the article as stated above. The fact that the Minnesota Transracial Adoption Study retested the children post-adolescence is also mentioned in the article under "Uniform rearing conditions" which states "The children were restudied ten years later." As for the fact that Moore, Eyferth, and Tizard studies never retests the children, this is confirmed by materials already sourced in the article here and here. None of the cited sources to Moore, Eyferth, and Tizard give any indication of a retest. The fact that these studies have no follow up was also previously mentioned in earlier versions of this article as seen here

So it's unclear to me what Aprock's objection could be. Is it that heritability of IQ is higher post-adolescence? Is it that Minnesota Transracial Adoption Study does retest post-adolescence? Or is it that Moore, Eyferth, and Tizard never does retests post-adolescence? BlackHades (talk) 03:38, 28 December 2012 (UTC)

The source does not mention anything about retesting the children in post-adolescence. If I somehow missed the section where that is discussed, I apologize. Otherwise, a pointer to the page and paragraph would be helpful here. If you're arguing that we should include content describing what is not in the source, that probably won't pass muster. aprock (talk) 03:58, 28 December 2012 (UTC)

The issue of lack of retesting post-adolescence in the Moore, Eyferth, and Tizard studies is mentioned here and here. I can add those citations. It just didn't seem necessary since it was seemed clear these studies did not ever retest. Would you have any objections to simply adding these new citations? BlackHades (talk) 04:31, 28 December 2012 (UTC)

Here's another source from the book "The Scientific Study of General Intelligence: Tribute to Arthur Jensen" by Helmuth Nyborg. pg. 402.

"Moore study differs from the Minnesota study in two possibly relevant ways. First, Moore's sample was smaller - there were 9 children whose biological parents were Black who were adopted by White families and there were 14 similarly adopted children who were biologically biracial. Second, the children were administered IQ tests at an earlier age than the follow-up tests administered in the Minnesota study. The data would be more dispositive if the sample were larger and if the children were older." BlackHades (talk) 05:35, 28 December 2012 (UTC)

It appears that you are suggesting that we introduce your own original research into the article. If you don't have a source for the content you want to introduce into the article, then it doesn't belong. If you want to include the criticism of Moore, I don't think that's out of line, but applying it to all the studies when there are not sources to support that is original research. aprock (talk) 17:18, 28 December 2012 (UTC)

There would be the similar criticisms for Eyferth and Tizard. Since like Moore, they all have the same issue in regard to the lack of retesting. I'll find them and post them here...Here's one for Eyferth. I'll search for Tizard right now.

"The children tested in this study [Eyferth] were young. At these ages analyses of performance on tests of intelligence usually find some evidence of between family environmental influences on performance." ---The Scientific Study of General Intelligence: Tribute to Arthur Jensen by Helmuth Nyborg. pg. 406. BlackHades (talk) 21:42, 28 December 2012 (UTC)

Here's Tizard.

"Tizard (1974) compared Black (African and West Indian), White, and mixed-parentage children and found no significant differences among the three groups on several language comprehension tests and on the Wechsler Preschool and Primary Scale of Intelligence(WPPSI); the single significant difference was in favor of the non-White children. Moore (1986) found that at age 7, 23 Black children adopted by middle-class White families had a mean IQ of 117, whereas a similar group of children adopted by middle-class Black families had a mean IQ of 104, both significantly above the national Black mean of 85. To be more informative, future studies need to be supplemented by follow-up testing, as in the Minnesota Study. Behavior genetic studies consistently show that, as people age, their genes exert ever more influence, whereas family socialization effects decrease (see Figure 3)."---Rushton, J.

Neanderthal DNA a factor?

Given that a couple of years ago, Eurasians were found to have some neanderthal DNA (with Asians having even more than Europeans) but people of African heritage having none, there is a correspondence between IQ results and neanderthal DNA. Is anyone aware of any studies into this? groovygower (talk) 04:15, 2 January 2013 (UTC)

IQ of Koreans adopted by White families studies

There are several studies listed in the article on the IQ of Blacks adopted by White families, however studies done on Koreans adopted by White families seem strangely omitted.

There are several studies done on the IQ of Korean children by White families in Western countries such as US, Belgium, and Netherlands. (Winick 1975, Clark & Hanisee 1982, Frydman & Lynn 1989, Stams 2000). These studies should be added to the article. But before I add them, would there be any objections to adding these studies? Would there be any reasons why these studies are not in the article currently? BlackHades (talk) 00:19, 6 January 2013 (UTC)

I say go for it. Wikipedia is known for it's NPOV, so even if something 'seems' contraversial, if it's backed up with evidence (as studies are ), it's definately worth mentionning. groovygower (talk) 01:56, 9 January 2013 (UTC)

Korean adoptees have been studied[20] in Sweden, too. They score slightly higher than the native population whereas other non-Western adoptees (mainly Indians, Thais, Chileans, Sri Lankans, Colombians, Ethiopians, and Ecuadorians) score substantially lower than the native population. There are comparable differences in school performance. However, we should find and use some secondary source that sums up these various studies.--Victor Chmara (talk) 14:22, 9 January 2013 (UTC)

I'm trying to find the time to put this all together. Trying to collect relevant studies, secondary sources, and create tables of the results. Any assistance from others to help put this together will be greatly appreciated. BlackHades (talk) 06:52, 18 January 2013 (UTC)

Some of Richard Lynn's books may discuss these studies. Lynn is a highly opinionated author, but if you intend to include this material, citing his books would be preferable over citing the primary papers. --Mors Martell (talk) 06:53, 21 January 2013 (UTC)

Interpretation of AAA 1994 statement.

The lede reports the AAA 1994 as saying that "intelligence cannot be biologically determined by race". The statement actually says that "The American Anthropological Association (AAA) is deeply concerned by recent public discussions which imply that intelligence is biologically determined by race." The lede does not seem to reflect well the content of the statement. Could this be improved? Might I suggest replacing the sentence with: "The position of the American Anthropological Association is that variation in intelligence cannot be meaningfully explained by dividing a species into biologically-defined races." Thoughts?--Atethnekos (Discussion, Contributions) 22:06, 17 January 2013 (UTC)

Given...

WHEREAS, differentiating species into biologically defined "races" has proven meaningless and unscientific as a way of explaining variation (whether in intelligence or other traits), 

— American Anthropological Association Statement on "Race" and Intelligence, 1994.

"Race" thus evolved as a worldview, a body of prejudgments that distorts our ideas about human differences and group behavior. Racial beliefs constitute myths about the diversity in the human species and about the abilities and behavior of people homogenized into "racial" categories. The myths fused behavior and physical features together in the public mind, impeding our comprehension of both biological variations and cultural behavior,implying that both are genetically determined. Racial myths bear no relationship to the reality of human capabilities or behavior. Scientists today find that reliance on such folk beliefs about human differences in research has led to countless errors.

— American Anthropological Association Statement on "Race", 1998. (emphasis mine)

..we certainly could expand the sentence with more specifics. — ArtifexMayhem (talk) 08:00, 22 January 2013 (UTC)

POV editing

It appears that Black Hades has decided to approach editing the article in a distinctly POV manner, removing sourced material which does not support the hereditarian view ([21], [22], [23]), and adding content which supports the hereditarian view ([24], [25], [26], [27], [28]). I suggest that more care be taken in done bringing the article into a neutral state. aprock (talk) 07:22, 4 February 2013 (UTC)

Absolutely 100% incorrect. This article is currently terribly out of NPOV due to some editors, that support the environmentalist viewpoint, that have been systematically practicing WP:Truth. Hence a lot of highly relevant studies that meets WP:Verifiability published in major mainstream journals have either been completely omitted or mischaracterized (e.g. Templeton, Flynn) if they even remotely hint at the possibility of genetic contribution. All relevant studies that meets WP:Verifiability should be EQUALLY represented and positions by major scientific figures should be accurately presented in order to meet NPOV. BlackHades (talk) 07:58, 4 February 2013 (UTC)

In regards to you reverting my removal of Wicherts. Wicherts statements are directly a rebuttal to Rushton's position which was previously in this article. Rushton's position was removed at some point but not the rebuttal to it. This is just one of the many examples of editors here practicing WP:Truth. Why do you want to keep a rebuttal to something that no longer exists in the article? Either Rushton's position should be re-entered into the section along with Wicherts's direct rebuttal of Rushton or neither should be there. I'm trying to make this page NPOV which some editors clearly are not. BlackHades (talk) 08:09, 4 February 2013 (UTC)

Rushton's work is cited both in the section text and references. At the same time, Witchert's critique discusses the issue more broadly than simply referring to Rushton's work. I suggest you take better care to read the sources, and present them in a balanced manner instead of just deleting relevant sourced material. Your attempts to make the page "NPOV" are not clearly achieving that goal. In fact, a cursory review of your edits indicates that you may be achieving the opposite. aprock (talk) 08:12, 4 February 2013 (UTC)

Rushton's work is only cited to criticize it. His position and POV is never given. Regarding your statement of Wicherts, I agree there is some more broadly discussed critiques than just Rushton, that in retrospect, does belong there. But the ones specifically tailored to Rushton does not belong there. Not without re-entering Rushton's position and POV. It makes no sense to rebut something that's not even there. BlackHades (talk) 09:28, 4 February 2013 (UTC)

Why is there so many relevant studies that meet WP:Verifiability that was completely omitted from this article? For example, studies relating to the heritability of brain size, trans-adoption studies of Koreans, the complete lack of criticism or rebuttals of environmentalist studies such as Witty and Jenkins (1936), the complete mischaractization of Templeton's position, inaccurate figures of the Shuey's study, etc. You can't deny that some editors, in support of the environmentalist position, are guilty of systematically practicing WP:Truth that have made this article completely out of NPOV. BlackHades (talk) 08:33, 4 February 2013 (UTC)

If you think there is a serious problem with the edits of particular contributors, I suggest you take your issues to WP:AE. This article is covered by WP:ARBR&I, and the proper sanctions can be considered there. aprock (talk) 08:41, 4 February 2013 (UTC)

The heavy violators seem to no longer be editing so I don't feel it's necessary to go to WP:AE at this point. However, a lot of their WP:Truth editing still exists in this article and that should be addressed for NPOV. Which is what I'm doing. BlackHades (talk) 09:09, 4 February 2013 (UTC)

In regards to your revert of my changes to the "Genetic Arguments" lede. How is the previous lede more NPOV than the changes I made? The American Anthropological Association never states "reject any genetic contribution". They state they don't agree with the implication "that intelligence is biologically determined by race" which is what I changed it to. And the American Psychological Assocation clearly states that their position is that there is not enough evidence to support either the environmentalist position nor the genetic position. To try to omit one or the other would not be NPOV. And to specifically state Rushton, Jensen, Murray, and Herrnstein is both not NPOV and undue weight. There is certainly more scientists than these four that support the hereditarian position which is why it was changed to "a number of scientists". You haven't given any reasons for this revert. BlackHades (talk) 08:55, 4 February 2013 (UTC)

Again, you appear to be arguing strictly from the perspective that the article does not give due weight to the hereditarian point of view. On the contrary, as it currently stands, the article gives undue weight to scientifically marginalized research of hereditarians. This is in no small part due to the fact that the only editors which have been making extensive edits over the last four years have been the kind of hold the hereditarian hypothesis as primary. Please reread the APA report. While the specific wording might due with some improvement, the APA does not regard genetic and environmental explanations as equally relevant. aprock (talk) 15:24, 4 February 2013 (UTC)

I respectfully disagree. At some point in the past, yes there were editors in support of the hereditarian view, that engaged in WP:Truth, that made the article not NPOV. But currently as the article stands right now, the opposite is true. It is editors in support of the environmentalist view, that have engaged in WP:Truth, that has now caused the article to give undue weight to the environmentalist view while completely omitting or mischaracterizing highly relevant studies that meets WP:Verifiability as shown by my many examples above. You can clearly see this the way hereditarian views consistently have rebuttals to them while environmentalist views quite often does not. Even when plenty of sources that meet WP:Verifiability that is heavily critical of those environmentalist positions exists. BlackHades (talk) 19:15, 4 February 2013 (UTC)

By all means, continue to edit the article to improve it. The most important advice I can give you would be to refrain from introducing content based on primary sources, especially those with no secondary source to give weight to the content. aprock (talk) 15:57, 5 February 2013 (UTC)

The most glaring issues I think are resolved now. There are some sections that still needs some adjustment but overall there seems to be better balance. In regards to the POV tag. That tag was added back in December 2011 when Hipocrite was making major changes to the "Genetic arguments" lede and Victor Chmara was reverting them. The current lede looks much different now than any of the versions back then. It more accurately portrays AAA and APA and there is more balance overall. Unless there's a specific objection you have, I don't see the need for the tag anymore. BlackHades (talk) 03:01, 6 February 2013 (UTC)

Take a look at recent edits and try telling me editors that support the environmentalist position isn't practicing WP:Truth by removing relevant sourced content. Including Wicherts which you yourself said was "relevant sourced material". BlackHades (talk) 04:36, 6 February 2013 (UTC)

Removing relevant cited material.

69.115.61.253 and KillerChihuahua appear to be making repeated attempts to remove relevant cited material from the article that clearly meets WP:Verifiability with several primary and secondary sources. The material in question being average brain size differences. Average brain size differences have been acknowledged by both hereditarians and environmentalists and discussed in length by both in what relation it may or may not have on IQ gaps.[29] [30] In accordance with WP:point of view neutrality requires that due weight be given. And for editors to not practice WP:Truth by removing relevant sourced material that meets WP:Verifiability. BlackHades (talk) 23:52, 6 February 2013 (UTC)

69.115.61.253 first attempted to removed said cited material on January 3, 2013 seen here. It was quickly reverted by The Devil's Advocate here He appears to be reattempting to remove the same cited material he has previously attempted last month. BlackHades (talk) 23:52, 6 February 2013 (UTC)

Obviously, as you can easily read from our edit summaries, we don't consider your material to be relevant at all. There is no "due weight" to give to something which is only marginally related to the topic of this article. Your POV pushing and edit warring to include this questionable content, whch only serves to underscore unfortunate racist biases, is hardly improving this article - quite the contrary.

Whether YOU believe the material is relevant or not is completely irrelevant when countless number of reliable sources absolutely consider it relevant. POV pushing through WP:Truth will NOT be tolerated. BlackHades (talk) 01:55, 7 February 2013 (UTC)

Your desired additions are a violation of WP:SYNTH. You are edit warring to include questionable information. I strongly advise you to gain consensus for these edits before reverting again. KillerChihuahua 04:35, 7 February 2013 (UTC)

I'm not going to go through and type the issues with each and every one of your references, but for example, the pubmed (second from end) is about the human FACE. I cannot begin to say how inappropriate that source is for this article. KillerChihuahua 04:52, 7 February 2013 (UTC)

The pubmed article you speak of was NEVER a source in this article. I was simply refuting your assertion and claim that brain size differences is not "relevant" and unimportant. Numerous amount of studies in WP:reliable sources will say otherwise. You still haven't explained why your personal opinion should override the collective opinion and positions of WP:reliable sources. Violation of WP:SYNTH? Where? How? What line? This is clear POV pushing. You don't delete content that meets WP:Verifiability simply because you don't want it or like it. And the references below? Simply dismiss them? Pretend they don't exist?

"Using data from magnetic resonance imaging (MRI), autopsy, endocranial measurements, and other techniques, we show that (1) brain size is correlated with cognitive ability about .44 using MRI; (2) brain size varies by age, sex, social class, and race; and (3) cognitive ability varies by age, sex, social class, and race. Brain size and cognitive ability show a curvilinear relation with age, increasing to young adulthood and then decreasing; increasing from women to men; increasing with socioeconomic status; and increasing from Africans to Europeans to Asians."

"Three studies of 9 and 10 yr old children in Northern Ireland and England obtain correlation coefficients of +0.18 to +0.26 between head size and intelligence.

"Data are reported and analyzed for a sub-sample of 100 Asian Americans. The Asian sub-sample averaged a higher IQ (110) at age 7 than did the white (102) or the black sub-samples (90). At birth, 4 months, 1 year, and 7 years, the Asians averaged a larger cranial capacity than did the whites or blacks despite being smaller in stature and lighter in weight (at age 7, Asian z scores from -0.20 to -0.40 in height and weight). Head circumference (or cranial capacity) at birth correlated .46 with head circumference (or cranial capacity) at age 7 which correlates .21 with IQ test scores at age 7."

"Scores on 17 diverse tests of cognitive abilities obtained from 82 pairs of monozygotic (MZ) and 61 pairs of dizygotic (DZ) twins were correlated with head size. A general factor, or psychometric g, was extracted from the tests, and g factor scores were found to be correlated with head size variables not only within individuals, but within twin pairs and between twin pairs. The size of the various tests' g loadings predicts the degree to which the tests are correlated with head size. This finding adds one more biological variable—head size and, by inference, brain size—to the list of other biological variables reported in the literature as showing a significant relation to psychometric g, the general factor common to all cognitive tests. Also, the varying magnitude of the mean difference between groups of white and black children on the 17 tests is related to the tests' loadings on g, on spatial ability, and the tests' correlations with head size."

Jensen, Arthur. (1994) Psychometric g related to differences in head size Personality and Individual Differences 17(5). pg 597-606.

"The most extensive study of race differences in endocranial volume to date measured 20,000 skulls from around the world and reported East Asians, Europeans, and Africans had average cranial volumes 1,415 cm3, 1,362 cm3, and 1,268 cm3 respectively (Beals, Smith, & Dodd, 1984). Because 1 cubic inch of brain matter contains millions of brain cells and hundreds of millions of synapses or neural connections, these group differences in average brain size may explain group differences in average IQ."

Ok, I've gone through these and done a preliminary assessment. We are left with three sources which might be useful for this article. We will need to examine each one carefully to determine whether it is indeed a reliable source from experts, and if so, whether it is applicable to this article and if so, how to incorporate any content therefrom. I suggest a new talk page section, leaving behind the wall of links and inappropriate sources, and taking the three which pass muster there for discussion. KillerChihuahua 07:02, 7 February 2013 (UTC)

Wow. Thanks very much for watching this article. BlackHades, I also strongly suggest you not replace any of this material without consensus. Dougweller (talk) 05:45, 7 February 2013 (UTC)

Replace content? You mean restore relevant content that many editors from all different viewpoints worked tirelessly together to create? No consensus required for KillerChihuahua to remove massive sections of the article in a POV attempt but somehow I need consensus on restoring content that many editors worked tirelessly together to give due weight to? With relevant WP:Verifiability content in order to achieve NPOV? BlackHades (talk) 07:00, 7 February 2013 (UTC)

Doug, Steve Rubenstein asked me to watch this article a while back, and I'm sorry to say I haven't put in a lot of effort to it, but I'm trying to bump it up on my priority list. I feel guilty every time I see it on my watchlist. :-( KillerChihuahua 06:22, 7 February 2013 (UTC)

@BlackHades: If starting a new talk page section as suggested by KillerChihuahua, please omit mention of other editors. For example, the current section has an aggressive heading that identifies two editors, and the opening comment makes some grand assertions regarding TRUTH. Please stick to article content: what text should be added or changed or not removed, and why. There will be a time for discussing other editors if this article becomes the subject of arbitration enforcement (see WP:ARBR&I). Johnuniq (talk) 08:10, 7 February 2013 (UTC)

The previous text that KillerChihuahua keeps removing was already properly sourced. He has yet to state which lines in that text he objects to. He simply made a blanket deletion stating that nothing in there was relevant to the article. Here is the text in question. Each line has the proper reliable sources listed. We can replace the previous refs with refs that KillerChihuahua deems "possibly acceptable" above if that satisfies him. The irony is that the previous text was already undue weight to the environmentalist position. Since it mentions the existence of average brain size differences, which is acknowledged by both hereditarians and environmentalists, but only gave the interpretation of what its cause and effects are by an environmentalist known as Wicherts. A hereditarian interpretation is never given here even though plenty of WP:reliable sources exists for it. Which makes me wonder how much more up in arms people would be if this section actual was NPOV with fair weight and contained both hereditarian and environmental interpretations of average brain size differences. BlackHades (talk) 08:47, 7 February 2013 (UTC)

“ Several studies have reported that races overlap significantly in brain size but differ in average brain size. The magnitude of these differences varies depending on the particular study and the methods used. In general, these studies have reported that East Asians have on average a larger brain size than whites who have on average a larger brain size than blacks. Other researchers have also found variation in average brain size between human groups, but concluded that this variation should be viewed as being based on biogeographic ancestry and independently of "race".

Wicherts writes that there is no reason to suppose that brain size is environmentally insensitive and that even if race differences in brain size are assumed to be entirely genetic in origin, they still leave 91–95% of racial IQ gap unaccounted for.

”

The comment just above has too much off-topic commentary, with over half its content referring to other editors. I have not yet formed a view on the material, but was any reason given for its removal (for example, in an edit summary)? If so, has that reason been addressed? Johnuniq (talk) 09:17, 7 February 2013 (UTC)

First revert occurred by 69.115.61.253 January 3, 2013 here. It was quickly reverted by The Devil's Advocate here. 69.115.61.253 comes back a month later and makes the same 2nd revert attempt here. Which I reverted here. Followed by KillerChihuahua reverting here. Neither 69.115.61.253 nor KillerChihuahua made any attempts to discuss in talk before removing such huge chunks of relevant cited material. KillerChihuahua then proceeds to edit war while at the same time accusing me of edit warring while giving extremely vague "it's not relevant" and "it's racist" end of discussion statements. Nevermind the fact that it's backed up by several WP:reliable sources. Never responds to my question exactly what line he has an issue with and why. Never responds to why his personal opinion should override and has the power to censor the opinions and positions expressed in WP:reliable sources. BlackHades (talk) 09:50, 7 February 2013 (UTC)

All of the above comment is off-topic for this article talk page. If you believe that "KillerChihuahua then proceeds to edit war", I recommend raising the matter at WP:AE because this article and talk page are "currently subject to active arbitration remedies" (see the box at the top of this page). The talk page of an article is the wrong place to talk about other editors. If necessary, that can be further explained at WP:AE. As mentioned above, please stick to article content: what text should be added or changed or not removed, and why. There is a peripheral mention of "racist" in this section, but the core of KC's comment is 'There is no "due weight" to give to something which is only marginally related to the topic of this article'—that is a concrete assertion that is suitable for discussion on an article talk page. Johnuniq (talk) 10:15, 7 February 2013 (UTC)

That assertion by KC would be wrong given how many WP:reliable sources there are that specifically mention the interaction of brain size, intelligence, and race all together. Including the refs that were already in the sourced text that KillerChihuahua removed. BlackHades (talk) 10:30, 7 February 2013 (UTC)

BlackHades has been warned by me for 3RR and by another Admin concerning the ArbCom sanctions and advised to work out a consensus here before making any more controversial edits. Dougweller (talk) 10:27, 7 February 2013 (UTC)

I would like to note that my reason for restoring the material before was because the dispute over racial differences in brain size is a noteworthy aspect of the race and intelligence debate and the IP's rationale for removal was premised on whether the claims were "valid" or not, rather than any legitimate policy claim. Looking further there may be some synthesis involved with some of the sources, but there are other sources that are clearly about the theory that differences in brain size indicate racial differences in intelligence. A section on brain size would certainly be appropriate in this article and not undue, but the material should be better sourced.--The Devil's Advocate _{tlk. cntrb.} 00:46, 8 February 2013 (UTC)

Agreed. Removing these huge relevant sections is not helping this article. BlackHades (talk) 01:08, 8 February 2013 (UTC)

I'm assuming there's no objection that the deleted text in question meets WP:Verifiability as I've repeatedly stated it does and no one has suggested otherwise. So it seems the only question is whether the text in question is relevant or "marginally related" to this article as KillerChihuahua suggests. I would ask that editors review the references that was listed in the text that KillerChihuahua deleted which includes among others:

"The world database was summarized by Rushton (1995 pp 126-132, Table 6.6) from autopsies, endocranial volume, head measurements, and head measurements corrected for body size, and found in cm3 or equivalents: East Asians and their descendants = 1,364, Europeans and their descendants = 1,347, and Africans and their descendants = 1,267. The review found the overall mean for Asians to be 17cm3 more than that for Europeans and 97cm3 more than that for Africans. Mean IQ scores parallel those in average brain size, with Asians averaging an IQ of about 106, Whites averaging 100, Blacks averaging 85."

Rushton, J Philippe. (1997) Cranial size and IQ in Asian Americans from birth to age seven Intelligence 25(1). pg 7-20.

"Also, the varying magnitude of the mean difference between groups of white and black children on the 17 tests is related to the tests' loadings on g, on spatial ability, and the tests' correlations with head size."

Jensen, Arthur. (1994) Psychometric g related to differences in head size Personality and Individual Differences 17(5). pg 597-606.

"Sex combined brain cases from Asia averaged 1380 cm3, from Europe averaged 1362 cm3, and from Africa averaged 1276 cm3. With some measures of cognitive performance, analyses from international as well as US samples suggest that a parallel exists with the brain-size data such that Mongoloid populations average higher than Caucasoid and Negroid populations. Moreover, several studies have demonstrated a positive within-race correlation between head permimeter measured by tape and scores on IQ tests."

Rushton, J Philippe. (1991) Mongoloid-Caucasoid Differences in Brain Size from Military Samples Intelligence 15, 351-359.

These were the references in the text that KillerChihuahua deleted. How can KillerChihuahua make the claim that the text he deleted is not related to this article of race and intelligence when directly in the references of the text he deleted, there are studies compare brain size, intelligence, and race and their relationship to each other. Including those that he now says are "possibly acceptable". He doesn't have to agree with the references but it's clear that this text is relevant and should be in the article in one form or another. No one is saying that the references are true or not but its relevancy to this article is certainly there. If he has issues with the way it was worded, then he should have brought it up instead of doing a blanket complete deletion. Accusations that I'm violating WP:SYNTH and promoting racism when all I was doing was following WP:Neutral point of view and WP:Verfiability was completely unnecessary. BlackHades (talk) 12:09, 7 February 2013 (UTC)

I see several problems with this revert by BlackHades (Do not remove relevant cited material that meets WP:Verifiability. Please understand that your personal opinions doesn't overrule countless reliable sources that absolutely considers it relevant and important to the discussion. Please see talk.)

I.

Individual brain size is highly heritable with a genetic correlation to total brain size ranging from 0.66 to 0.97. In a review of six MRI studies that reported genetic correlation to total brain size, 5 out of 6 studies showed a correlation above 0.89.

In a study of the head growth of 633 term-born children, it was shown that prenatal growth and growth during infancy were associated with subsequent IQ. The study's conclusion was that the brain volume a child achieves by the age of 1 year helps determine later intelligence. Within human populations, Magnetic Resonance Imaging (MRI) studies conducted to determine whether there is a relationship between brain size and a number of cognitive measures have "yielded inconsistent findings with correlations from 0 to 0.6, with most correlations 0.3 or 0.4.". For postmortem studies the correlation is about 0.15. McDaniel (2005) analyzed 37 MRI studies assessing brain volume and intelligence and found an average correlation of 0.33. Positive correlation was found in all age and sex groups. It concluded "it is very clear that brain volume and intelligence are related".

While the above meets WP:V, none of the sources connect "race" and brain size. It's only purpose here is to support of a specific point of view by propping up selected sources below (i.e., it's WP:SYNTH).

II.

The difference in average brain sizes varies widely from country to country. For instance, the average brain size of the average Maasai person is larger than the average brain size of the average "Caucasoid" person in Egypt. According to Z. Z. Cernovsky, Rushton's study shows that the average cranial capacity of North American blacks is similar to that of Caucasians from comparable climatic zones.

This section twists the source by phrasing and omission in order to advance specific POV (including a WP:CHERRY Rushton cite). It does not meet WP:V and is in direct violation of WP:NPOV. Here's what the source actually says (emphasis mine)...

Within a given racial group, cranial capacity varies depending on the climatic zone. For example, the American Indians are spread over a wide variety of climatic zones and show a corresponding variation in skull size: those from warmer climates have smaller cranial capacity. This pattern is also true for other racial groups. Beals et al. concluded, on the basis of extensive statistical analyses, that correlations of brain size to race are spurious: smaller crania are found in warmer climates, irrespective of race. In fact, Rushton's own tabular summaries of cranial data, based on Herskovits (1930), clearly show these trends. In Rushton's summaries (1990b: see Table 2), the average cranial capacity for North American blacks (1622 cm³) is similar to the average for Caucasians (1621 cm³) from comparable climatic zones. Caucasians from warmer zones such as Cairo (1502 cm³) were similar to some of the black Africans, for example, the Masai (1508 cm³). It is only by "pooling" the black North American data with data for blacks from countries within hot climatic zones (notorious for famine and infant malnutrition that impede brain growth) that Rushton obtained an illusory support for his "genetic" postulates.

III.

Several studies have reported that races overlap significantly in brain size but differ in average brain size. The magnitude of these differences varies depending on the particular study and the methods used. In general, these studies have reported that East Asians have on average a larger brain size than whites who have on average a larger brain size than blacks.

The first two cites are red herrings (they do not connect "intelligence" to brain weight) used to mask the undue weight being given the next three cites : Jensen, Rushton and Rushton.

IV.

Other researchers have also found variation in average brain size between human groups, but concluded that this variation should be viewed as being based on biogeographic ancestry and independently of "race".

This appears to be a complete fabrication. Here's what the two sources actually have to say (emphasis mine)...

The explanation of human brain size difference has historically been colored by a search for "the cause." This traditionally focused upon difference in mental ability or race. Neither has been shown to have any significant direct effect. The distribution indicates that racial means are actually reflections of secondary correlation with climate. For example, Native Americans have a common ancestry but almost the entire range of variation in cranial capacity. The cognitive model requires that mental function change not only the internal organization of the brain, but also its absolute size. It is not supported by any preponderance of direct evidence from either psychology or ethnology.

...

With an ever broader perspective, cognition is part of the answer in an indirect manner-through cultural inventions which led to occupation of the world's diversity of ecological zones. "The cause," in short, does not exist. Explaining the variation in human brain size requires a synthetic theory, portions of which best apply to given particulars of time and space.

3. Rushton's cranioracial variation is contradicted by evolutionary anthropology. Rushton (1990:786) takes cranial measurements from a study by Beals, Smith, and Dodd (1984) without mentioning that study's finding that while climate variables were strongly correlated with cranial variation, "race" and cranial variation had low correlations.

V.

Wicherts writes that there is no reason to suppose that brain size is environmentally insensitive and that even if race differences in brain size are assumed to be entirely genetic in origin, they still leave 91–95% of racial IQ gap unaccounted for.

This is not found in the two sources provided. Using the correct source we find more POV pushing by omision (any source is a good source if it can be mined for a "there is an IQ gap" quote) (emphasis mine)...

Rushton’s figures are based not on contemporary MRI measurements of white and gray matter volume, but rather on outdated external or postmortem cranial measurements. Given the correlation between cranial capacity as measured externally and intelligence of around .20 (Rushton & Ankney, 2009), the Black-White gap in brain size cannot explain much of the IQ gap. Even if cranial capacity had a causal effect on g, then the Black-White gap in brain size cannot explain more than: .6*.2*15 = 1.8 IQ points. If we were to believe that the IQ gap between Africans and European Whites is 33 IQ points (Lynn & Vanhanen, 2006), then the brain size gap could explain a staggering 1.8/33 = 5% of the IQ gap. Thus, even under these terms, 95% of the IQ gap is left unexplained by brain size. With a correlation of .33 between brain volume and IQ as based on modern techniques (McDaniel, 2005), the gap in brain size can explain only 2.98 IQ points or 9% of the IQ gap. However, we are not familiar with studies that used modern methods to measure brain size in both European Whites and Africans, and we are not familiar with any studies of the heritability of IQ and/or brain size among Africans. Although race differences in brain size are in line with Rushton’s hypothesis, his hypothesis fails to impress us.

...

Another problem with the brain size hypothesis lies with the fact that sex differences in brain size are larger than race differences, yet studies involving representative samples, broad cognitive test batteries, and sound statistical methods consistently fail to show a clear sex difference in g.

I am going to remove remainder the section pending a replacement that is better aligned with our policies and guidelines. — ArtifexMayhem (talk) 12:56, 7 February 2013 (UTC)

Regarding I: Here is the full quote of Hunt/Carlson's McDaniel (2005) cite:

Example of Going Beyond Counting Genetic Variance: Rushton (1995) maintained that one of the reasons for the White–African American disparity in IQ scores is that Whites have larger brain sizes than African Americans. Leaving aside the issue of whether or not one accepts this particular argument, the argument itself illustrates a useful principle. Differences in brain size are associated with intelligence (McDaniel, 2005). Rushton has stated a hypothesis about a biological mechanism, known to influence intelligence, that might explain the difference. Rushton’s claim for a racial disparity in brain sizes was based on exterior skull measures. Further studies, using modern imaging techniques, may provide a more sensitive test of the hypothesis. It would not be appropriate to enter into a detailed discussion here. Our point is simply that discussing this sort of claim is far more likely to increase our understanding of the disparity than is arguing about the percentage of variance associated with biological or environmental variables.

Reviewing the disputed content, it looks nothing like this high level overview, and appears to be using the fact that McDaniel was cited as an excuse to include content from McDaniel that was not referred to, contrary to policy and guidelines. I would fully support inclusion of content which properly summarizes the Hunt/Carlson (2007). That's not what we have here. aprock (talk) 22:30, 7 February 2013 (UTC)

Regarding I: These studies, like McDaniel (2005), have been repeatedly mentioned in connection with the race and intelligence debate in reliable sources which makes it relevant. Including Hunt and Carlson (2007) which many editors here have already deemed a reliable source. Hunt and Carlson (2007) have also stated that Rushton's claim that brain size differences between races could be causing IQ gaps is a reasonable hypothesis that merits investigation. BlackHades (talk) 21:18, 7 February 2013 (UTC)

Also regarding I: "Rushton (1995) maintained that one of the reasons for the White–African American disparity in IQ scores is that Whites have larger brain sizes than African Americans. Leaving aside the issue of whether or not one accepts this particular argument, the argument itself illustrates a useful principle. Differences in brain size are associated with intelligence (McDaniel, 2005). Rushton has stated a hypothesis about a biological mechanism, known to influence intelligence, that might explain the difference."---Hunt and Carlson (2007) BlackHades (talk) 21:18, 7 February 2013 (UTC)

Regarding III: If preferred we can replace Rushton and Jensen refs with Lynn and Templer refs. The point is that enough WP:reliable sources exists that claim brain size gaps in the order of East Asians > Europeans > Africans and its possible relationship to intelligence that we cannot omit this information. Criticism of these studies should certainly be included as well but to omit this information entirely would not be fair weight. BlackHades (talk) 21:40, 7 February 2013 (UTC)

Being repeatedly mentioned makes it relevant according to how it is mentioned. What you cannot do is observe that a source is cited, and then ignore the secondary source content and perform your own synthesis on the primary source, which is what appears to be happening here. Again, content which summarizes Hunt/Carlson fairly should be fine. That's not what we have here. I'm not really sure why you are re-quoting the content I already quoted. aprock (talk) 23:55, 7 February 2013 (UTC)

I'm not requoting. I never wrote this here. This was written before you wrote yours and someone moved my comments down here. BlackHades (talk) 00:04, 8 February 2013 (UTC)

BlackHades is correct, Aprock; he wrote his posts prior to yours, but unfortunately violated talk page guidelines and placed his comments within ArtifexMahem's post. I moved them out of AM's post, here; I placed them below yours as a matter of simple editing convenience. KillerChihuahua 00:09, 8 February 2013 (UTC)

Ok, my comment still stands. The proposed McDaniel content sourced through Hunt/Carlson looks nothing like the actual citation to McDaniel that Hunt/Carlson make. As such, it is a not proper use of sources. aprock (talk) 00:10, 8 February 2013 (UTC)

Individual brain size to intelligence is important to mention and is relevant to this article. As it's consistently referred to in sources that explore this topic. It's as relevant as the issue of individual IQ heritability. Which is also mentioned and relevant to this article. In what context it should be mentioned is certainly open to debate but this blanket mass deletion has been completely unconstructive and violates WP:NPOV. Also the average brain size difference between East Asians, Europeans, and Africans is mentioned in several WP:reliable sources and absolutely deserves due weight. As should WP:reliable sources that has criticism of these studies. BlackHades (talk) 09:18, 8 February 2013 (UTC)

"Considerations" paper

A good bit of content is being sourced to Considerations Relating to the Study of Group Differences in Intelligence, which is linked here. Does anyone here have access to this paper? KillerChihuahua 13:49, 7 February 2013 (UTC)

Ok, have a copy of this and will be reading it to ensure it supports the bits in the article it is supposed to support. KillerChihuahua 02:17, 12 February 2013 (UTC)

Use of Hunt & Carlson 2007 in the lead.

Currently, the second paragraph of the lead (beginning with "Four contemporary classifications of position regarding study of differences in IQ based on race/ethnicity") summarizes the opening remarks of Hunt & Carlson (2007): "The investigation of racial differences in intelligence is probably the most controversial topic in the study of individual differences. Contemporary proponents can be found for each of the following positions:...". As the article is not about, nor does it cover (in any detail), "contemporary classifications of position regarding study of differences in IQ based on race/ethnicity" why are these "classifications" covered in the lead? — ArtifexMayhem (talk) 22:32, 11 February 2013 (UTC)

Removal of the existence of racial IQ gaps

It looks like KillerChihuahua now changed the following:

"IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups, with the average score of those with African ancestry lower than that of European ancestry and the average score of those with East Asian ancestry being higher than that of European ancestry. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause. Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate."

to this:

"One study performed in the United States indicated variation between different racial groups, with the average score of those with African ancestry lower than that of European ancestry and the average score of those with East Asian ancestry being higher than that of European ancestry. The study drew sharp criticism from Francis Collins, director of the genome program at the National Institutes of Health, as well as from a medical ethicist."

And then later decides he doesn't want this text at all and removes everything completely. Anyone that is well versed in this subject, regardless of whether they subscribe to the hereditarian or the environmentalist viewpoint, would clearly see that KillerChihuahua is POV pushing. Racial IQ gaps is fully acknowledged by both hereditarians and environmentalists. Nearly all of them. The APA in their report fully acknowledges these gaps exist. "Mainstream Science on Intelligence" also acknowledges the gap. As well as nearly every environmentalist cited in this article. From Flynn, Wicherts, and even extremists like Nisbett. This text has been in the article for several years and was never really disputed.

I've always had good intentions to get this article to NPOV. When there were disagreements with aprock for example, I put considerable effort to address concerns he had. Before adding transadoption studies of Koreans, I specifically asked for input and thoughts from other editors.

The fact that KillerChihuahua is allowed to POV push with impunity because he's an administrator and I'm told I'll be banned if I get in his way shows a very deep problem. Administrators should not be above the rules but apparently they are.

And if I'm going to be banned now just for expressing my concerns then so be it. BlackHades (talk) 23:31, 7 February 2013 (UTC)

Perhaps my edit summary was unclear. The author of the study being cited actually said his paper "offered no view on race and intelligence"[31] and he's actually annoyed people are using it to talk about race and intelligence. If the author of a paper states it has zero bearing on race and intelligence, I'm inclined to believe the study is not an appropriate source for this article. KillerChihuahua 23:37, 7 February 2013 (UTC)

That's completely irrelevant. It would have better to add rather than remove something that has consensus. You could of asked any of the other editors here to put in a ref. The fact that racial IQ gaps exist is nearly universally accepted. Regardless of whether they subscribe to the hereditarian or environmentalist view. There is dispute over the cause of it but not that it exists. The entire premise of this whole article is on "why does racial IQ gap exists?" and you want to remove the acknowledgement that it even exists at all? BlackHades (talk) 23:50, 7 February 2013 (UTC)

It is entirely relevant that the source being used to support that assertion, which is in fact not universally accepted (except by certain racists and race supremacist groups) had nothing to do with the article, and in fact had zero bearing on race and intelligence in any way. This article is on probation. Any contentious content must be impeccably sourced. KillerChihuahua 23:54, 7 February 2013 (UTC)

KillerChihuahua claims that racial IQ gaps are "not universally accepted (except by certain racists and race supremacist groups) had nothing to do with the article, and in fact had zero bearing on race and intelligence in any way.". Do we really need more evidence that KillerChihuahua is POV pushing? BlackHades (talk) 00:08, 8 February 2013 (UTC)

Misquoting someone out of context like this is a clear breach of the principle of decorum enumerated at ArbCom: WP:ARBR&I#Decorum. I think you need to step back. It appears that you are allowing frustration to get the upper hand. aprock (talk) 00:16, 8 February 2013 (UTC)

I'm not misquoting. And I'm pretty sure POV pushing would be a breach of ArbCom as well. BlackHades (talk) 00:29, 8 February 2013 (UTC)

Perhaps BH was not intentionally misrepresenting what I said. I'll try to rephrase: The source has nothing to do with race and intelligence. Also, your assertion that the points made in the paragraph are 'universally accepted' is demonstrably false; there is dispute. If you feel I have violated ArbCom sanctions, WP:AE is the place to file; I caution you, however, that all parties' actions will be examined. KillerChihuahua 00:34, 8 February 2013 (UTC)

Given that the APA and Mainstream Science on Intelligence both acknowledged the existence of racial IQ gaps, along with every environmentalist in the article that I'm aware of in this article, explain how it's false. You stated that racial gaps is only accepted by certain racists and race supremacist groups correct? BlackHades (talk) 00:43, 8 February 2013 (UTC)

As a side note, the correct phrasing is "you could have asked" not "you could of asked". The former is a suggestion for what I could have done; the second is simply poor English. I apologize if this seems at all snarky; this is a pet peeve of mine, and it is especially irritating to see in a conversation about intelligence. KillerChihuahua 23:58, 7 February 2013 (UTC)

KC, the existence of a racial IQ gap is well-documented and is one of the main points of discussion in the modern controversy so it is worth mentioning in the lede. Also, in removing that material you also removed well-sourced consensus material in the second half of the paragraph. The other material in the lede was undoubtedly supported by sources in the article body. I am sure you can find some more in the article body that support the first half of the paragraph as well.--The Devil's Advocate _{tlk. cntrb.} 23:59, 7 February 2013 (UTC)

Not sure what your point is; that is still in the article. I removed a paragraph which was about one study, which had nothing to do with race and intelligence and therefore should not be included in this article. KillerChihuahua 00:02, 8 February 2013 (UTC)

KC, the lede is a summary of material already included in the article so it was not about "one study", but the entire body of studies as supported in the article body. The sources in the lede are provided simply to back up particularly contentious claims. The source you refer to that mentioned Lahn was only specifically backing up the claim: "Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate." The material preceding that is all supported by sources in the article below.--The Devil's Advocate _{tlk. cntrb.} 00:27, 8 February 2013 (UTC)

Are we talking about the same edit? Please post a diff so we aren't talking past each other, thanks. KillerChihuahua 00:36, 8 February 2013 (UTC)

Yes, you rewrote the material in the lede first and then removed it entirely. The consensus-wording you removed and which was what the sources were there to support was:

Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate. Some researchers fear that the findings could be misused to perpetuate racial stereotypes, while others contend that the politicization of the field threatens to stifle important avenues of research.

All of that was supported by the sourcing provided in the lede, and was put in following a discussion several months ago on this talk page. The material preceding it was all there before the material quoted above and the relevant sourcing were added.--The Devil's Advocate _{tlk. cntrb.} 00:58, 8 February 2013 (UTC)

Ok then yes, we're talking about the same edits. No, that was not supported by the source. KillerChihuahua 02:01, 8 February 2013 (UTC)

Yes it is supported. There was a very long lengthy discussion to add that specific line to the article. Review it in archives. And what's your reasoning to remove everything before that sentence? I asked for a source anywhere on the article (or any reliable source period) that disputes the fact that racial IQ gaps exist. You've yet to respond. BlackHades (talk) 02:54, 8 February 2013 (UTC)

No, that is not how it works. I don't have to prove a negative; the onus is on the person desiring to add content to source it adequately, and even that is a little backwards. The optimum is to read the source material and write the article based on what that says. However, if you think certain content should be in the article, the burden falls to you to provide that sourcing, and gain consensus for your additions. The sources must meet WP:RS, and the content must be within policy. No one needs to go find sourcing contrary to what you want in the article. KillerChihuahua 03:01, 8 February 2013 (UTC)

Just to clarify. Your position on the existence of racial IQ gaps is "not universally accepted (except by certain racists and race supremacist groups)". Is this correct? BlackHades (talk) 03:32, 8 February 2013 (UTC)

This is talk page misuse. Stop asking about what you think are my personal views. I'm not your friend and we're not talking over coffee, this talk page is for discussing how to improve the article, not trying to learn what anyone's personal views are or are not. My position is null. Be done, now. KillerChihuahua 03:42, 8 February 2013 (UTC)

Your personal view is relevant whether you want to admit it or not. As it's clearly having an effect on the way you're removing massive amount of content and affecting the level of neutrality of the article. If it really is your position that the existence of IQ gaps is "not universally accepted except by racists and race supremacist groups" then it certainly has a direct impact on the way you readily remove content that has scientific consensus. Such as that racial IQ gaps does exist. There are a lot of disagreements hereditarians and environmentalists in the field have. As well as among editors here. But one thing that was never in dispute was that racial IQ gaps exists. The cause of it certainly has major dispute but not the existence. The APA considers the Black-White IQ gap as one of the "knowns" in their "knowns and unknowns" report. There are several published work that also highlights this fact. BlackHades (talk) 05:25, 8 February 2013 (UTC)

"African Americans, The relatively low mean of the distribution of African-American intelligence test scores has been discussed for many years. Although studies using different tests and samples yield a range of results, the Black mean is typically about one standard deviation (about 15 points) below that of Whites."

American Psychological Association. Task Force Report. 1994. Intelligence: Knowns and Unknowns

"The relationship between IQ scores and elementary cognitive task (ECT) performance is well established, with variance on each largely reflecting the general factor of intelligence. Also ubiquitous are Black–White mean differences on IQ and measures of academic success, like grade point average (GPA)"

KC, the lede is a summary of the article. Just look at any part of the article concerning the racial IQ gap and you will find the sources you desire I am sure. The lede is just there to summarize material that is already sourced in the article body. As to the rest of that paragraph, we had a long discussion here where you can review the evidence and argumentation that led to the wording in the lede. The material that you altered and then removed from the lede was well-sourced and accurate.--The Devil's Advocate _{tlk. cntrb.} 04:13, 8 February 2013 (UTC)

I'm well aware of WP:LEAD, TDA. I'm not sure why you keep telling me about it; surely you know I know about leads. Have you a suggestion to make to improve the article? Have you read the lead as it now exists? KillerChihuahua 04:17, 8 February 2013 (UTC)

My suggestion is that you restore the well-sourced and accurate wording that emerged out of talk page consensus as it was before you made any changes to it. Your claim that the material was not well-sourced is mistaken and was addressed thoroughly during that earlier discussion. Also, consider that I would not feel a need to remind you of the relevant guideline if I thought your edits were like those expected of someone who had knowledge of it.--The Devil's Advocate _{tlk. cntrb.} 05:36, 8 February 2013 (UTC)

I concurr. BlackHades (talk) 06:19, 8 February 2013 (UTC)

1. My view is irrelevant, as is yours and everyone else's. We write what the reliable sources say, not what we think - that would be a blog, not an encyclopedia.
2. As far as restoring "well sourced content" I've repeatedly quoted the source itself, which is that it has nothing to do with race and intelligence. That is why I removed it - you might as well source that content to a Mother Goose book, for all the support it gave the content it was supposedly supporting. The only thing we could possibly glean from that source is that racists tried to use it, and I could source that, very easily, from that source, but I personally think it would be WP:UNDUE to report that mis-use of that paper here.

I sincerely hope we are done discussing that particular source and its use in this article. KillerChihuahua 14:16, 8 February 2013 (UTC)

No we are not, because you are not even remotely representing that source accurately by any measure. The only instance where you quoted it was earlier above in this thread, to cherry-pick Lahn's statement about his study, which is not only completely irrelevant to the material being backed by the source but doesn't even show understanding of Lahn's own statement. The source is very much about race and intelligence and Lahn himself was very clear that not only did he not have an issue with his research being used as part of the debate, but that he was inclined towards the hereditarian view himself.--The Devil's Advocate _{tlk. cntrb.} 15:08, 8 February 2013 (UTC)

KC, reliable sources says racial IQ gaps exists. You're been provided reliable sources that explicitly state so. Please stop POV pushing. BlackHades (talk) 23:33, 8 February 2013 (UTC)

KC, you appear to have stopped responding back. And haven't addressed the concerns raised by either The Devil's Advocate or me. As you've stopped responding, and since no one else has objected to this text, I will soon move to restore this text barring no further objections. BlackHades (talk) 22:02, 11 February 2013 (UTC)

What text do you wish to restore, specifically? — ArtifexMayhem (talk) 22:10, 11 February 2013 (UTC)

Black is referring to the lede material, which stated:

IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups, with the average score of those with African ancestry lower than that of European ancestry and the average score of those with East Asian ancestry being higher than that of European ancestry. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause. Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate. Some researchers fear that the findings could be misused to perpetuate racial stereotypes, while others contend that the politicization of the field threatens to stifle important avenues of research.

The first portion was a normal summary of sourced material in the article body and the second portion about the controversy of the research was directly supported by multiple sources and was also a summary of sourced material in the article body.--The Devil's Advocate _{tlk. cntrb.} 23:40, 11 February 2013 (UTC)

What supporting sources are proposed for this addition, specifically? — ArtifexMayhem (talk) 00:48, 12 February 2013 (UTC)

Please review the above, where The Devil's Advocate and I have addressed this to KillerChihuahua. BlackHades (talk) 02:14, 12 February 2013 (UTC)

I don't want to get involved here, but here's a quick note from a mathematician. The term "racial IQ gap" is an abomination, as it almost certainly doesn't describe the phenomenon accurately. A gap isn't just a difference between two average values. It means that the individual with the lowest IQ from the high average IQ 'race' still has a higher IQ than the individual with the highest IQ from the low average IQ 'race'. For the 'black-white gap' that would imply that every perpetually unemployed 'white' illiterate alcoholic has a higher IQ than the US president. I doubt that this is a technical term. It sounds like a political fighting term that should never be used in Wikipedia's voice. Hans Adler 22:43, 11 February 2013 (UTC)

The term "racial IQ gap" is repeatedly used in reliable sources. But if this is the only dispute we can change the term to "gaps between average IQ scores of different racial groups". But we might be getting overly technical here. BlackHades (talk) 02:08, 12 February 2013 (UTC)

I haven't responded to the exact same question I've already answered multiple times. I fail to see the point in having to re-affirm that the source which was used stated clearly it had "no bearing on race and intelligence" and therefore the content was removed. I hope I am now done, but if not I suppose I'll have to repeat this again and again until it sinks in. It is not a suitable source for this article, full stop. KillerChihuahua 02:20, 12 February 2013 (UTC)

You're completely ignoring what The Devil's Advocate said. Instead of giving a generic response that addresses absolutely nothing he said, read his statement again and properly address his statements. Furthermore, you completely ignored my requests. And haven't responded back to any of the sources I listed for you. BlackHades (talk) 02:40, 12 February 2013 (UTC)

It would be helpful to give a summary which includes the proposed text, its position in the article, and the precise sources. Comments like "Please review the above" and "sources I listed" are not useful when a topic is contested, particularly in a section of 24K bytes. Rather than a list, the proposed source or sources is needed. Johnuniq (talk) 03:02, 12 February 2013 (UTC)

Disputed and proposed text is at the very top highlighted in blue. The text is a summary of the article per WP:LEAD. Sources are listed in the general article which KillerChihuahua seemed to acknowledge at some point saying "Not sure what your point is; that is still in the article." but he seems to be ignoring guidelines for WP:LEAD. He keeps talking about one source that was only related to one line in the mass of text he deleted, which was already accurately represented anyways and this one single line in question was already the result of consensus through talk earlier which is in archives. Which it doesn't appear he's read or gave a single comment about this consensus. This one line also is unrelated to the mass of other text he deleted, which he doesn't appear to give any reason for its deletion. BlackHades (talk) 03:28, 12 February 2013 (UTC)

The best way forward would be as suggested above: "It would be helpful to give a summary which includes the proposed text, its position in the article, and the precise sources." Please. — ArtifexMayhem (talk) 03:46, 12 February 2013 (UTC)

Already done. Proposed text is highlighted in blue at the very top. The Devil's Advocate also directly responded to you with the proposed text. But I'll copy and paste it again here:

"IQ tests performed in the United States have consistently demonstrated a significant degree of variation between different racial groups, with the average score of those with African ancestry lower than that of European ancestry and the average score of those with East Asian ancestry being higher than that of European ancestry. While the existence of racial IQ gaps is well-documented and not subject to much dispute, there is no consensus among researchers as to their cause. Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate."

Position is obviously the lead as it was removed from lead. Sources are in the body of the text as it's a summary per the guidelines of WP:LEAD. But I provided KillerChihuahua of even more sources if he's still doubting the validity of the text which I'll copy and paste again below. The one line that KillerChihuahua seems overly focused on would be the "Research into potential genetic causes for intellectual differences between races is controversial and has generated heated debate." line which was already thoroughly discussed and reached a consensus through talk earlier which can be reviewed in archives here.

"African Americans, The relatively low mean of the distribution of African-American intelligence test scores has been discussed for many years. Although studies using different tests and samples yield a range of results, the Black mean is typically about one standard deviation (about 15 points) below that of Whites."

American Psychological Association. Task Force Report. 1994. Intelligence: Knowns and Unknowns

"The relationship between IQ scores and elementary cognitive task (ECT) performance is well established, with variance on each largely reflecting the general factor of intelligence. Also ubiquitous are Black–White mean differences on IQ and measures of academic success, like grade point average (GPA)"

Pesta, Bryan. (2008) Black–White differences on IQ and grades Intelligence 36. pg 323-329.

"The 1.1 standard deviation difference in average IQ between Blacks and Whites in the United States is not in itself a matter of empirical dispute"

Rushton, J Philippe. (2005) Thirty Years of Research on race..

"It is widely accepted that race differences in intelligence exist.”

Lynn, Richard. (2006) Race Differences in Intelligence

"The bell curve for whites is centered roughly around IQ 100; the bell curve for American blacks roughly around 85"

@Artifex and John There is no "proposed text" as it were, since that implies a new change. Rather, there is an absurdly misguided deletion of consensus wording and no meaningful defense of said deletion. KC has made numerous errors with regards to that material that suggest there was no careful consideration of policy and sourcing on KC's part. We shouldn't have to re-hash what was already discussed in depth to someone who has already been shown the relevant discussion and demonstrated no willingness to further justify the changes beyond an obviously misguided objection. I am adding the material back in and KC should instead be explaining to us why the material should be removed when it is well-sourced and previously got a non-partisan consensus from multiple editors.--The Devil's Advocate _{tlk. cntrb.} 04:28, 12 February 2013 (UTC)

The citations in the text you restored don't appear to support the statements therein. Can you please show where the Regalado article supports any of the material in the first two sentences to which it is attached as a supporting citation? Guettarda (talk) 04:56, 12 February 2013 (UTC)

It is the lede so citations aren't necessary for every statement as anyone who is familiar with the relevant policies would know. The first two sentences were there, without contention, well before the other material was added because they accurately summarize sourced material in the article body. I explained this already in this very discussion. The section of the article entitled "group differences" is one area where you can find all the necessary sourcing and material that supports the summary provided in the first two sentences. I added the sourced material after those sentences some time later per a consensus decision on this talk page that I have already linked to in this discussion.--The Devil's Advocate _{tlk. cntrb.} 05:31, 12 February 2013 (UTC)

Citations aren't necessary in the lead. But once you include them, they need to support the material to which they are attached. When you restore material to the article, you're responsible for it. You added the material. It has sources, which makes it appear as if the statements are supported by the sources. Your edit, therefore, is misleading. That's the problem with blindly reverting. I have already warned you about misrepresenting sources. You can't be so cavalier in your attitude towards factual accuracy. Guettarda (talk) 05:42, 12 February 2013 (UTC)

They aren't "attached" to the first two sentences and there is no requirement for some sort of "buffer citation" just to distinguish what is being supported by a given citation in the lede. If it would make you feel better we can add one after the first two sentences, but none of your arguments support deleting the paragraph in its entirety. There was no "blind reverting" on my part, just restoration of appropriate material based on policy and sourcing.--The Devil's Advocate _{tlk. cntrb.} 05:59, 12 February 2013 (UTC)

Yes, they are attached. You obviously don't understand established practice of citing sources. If this is a mistake, you need to learn from it and adapt your editing practices. You will never learn from your mistakes if you respond in this aggressive fashion every time someone points out that you have made a mistake. Back home we have a great expression for this, "wrong and strong". Guettarda (talk) 15:33, 12 February 2013 (UTC)

Guettarda, could you please review the list of sources I provided above? From the APA, Mainstream Science on Intelligence, Pesta, Rushton, Lynn. Also please review the "US Test Scores" section of the article. If it'll end this discussion, we can add one of sources as a citation. Enough sources has been provided to support the text. With not a single source anywhere in the article that contradicts it. It's time to move on. BlackHades (talk) 06:43, 12 February 2013 (UTC)

Even more sources. "The existence of sometimes large group differences in intelligence is as well-established as any fact in the social sciences". Gottfredson, Linda. 1994. Egalitarian Fiction and Collective Fraud Society 31(3) pg 53-59. There's been enough sources provided. Not a single counter source has been provided. We're moving on. This is being restored. BlackHades (talk) 08:28, 12 February 2013 (UTC)

1. Sources without context are meaningless. 2. "This is being restored" is inconsistent with the spirit of Wikipedia editing. (This is especially important on an article subject to arbcomm sanctions.) Please re-think your approach here. Guettarda (talk) 15:29, 12 February 2013 (UTC)
