Lead
@Closed Limelike Curves, IRV is not my favorite form of voting either and is overhyped but I still think the article should not take such a strong stance against it when there are reliable sources that clearly dispute many of your points. This is not the first article where this has been an issue. Let me know if you have any questions on the flags that were added Superb Owl (talk) 05:16, 30 August 2024 (UTC)
- Hi,
- sadly have to agree. Statements like "The method has had little academic support in social choice theory since the field's inception" or "Modern research into voting systems has instead tended to focus on majority-choice and rated voting systems" just do not seem like correct statements about modern social choice theory. I decided to delete that paragraph for now, as I think it is too far removed from being neutral or even true. Jannikp97 (talk) 09:16, 30 August 2024 (UTC)
- If you disagree, I'd be happy to see citations to sources showing strong support for IRV among social choice theorists. I've added the Laslier 2012 poll showing a majority of polled academics in the field disapproving of IRV.
- I'm struggling to think of a single social choice theorist who considers IRV better than both Condorcet and cardinal methods. Sure, there's plenty of disagreement in the field about the relative value of these two classes, but I don't think I've ever seen someone with substantial experience in the field who thinks IRV is better than both sets of rules. – Closed Limelike Curves (talk) 19:10, 30 August 2024 (UTC)
- You consistently try to equate IRV with plurality and refuse to add any context that considers that IRV could be an improvement upon plurality (very well sourced). It is true that condorcet and cardinal methods probably are an improvement to IRV, but that does not justify scrubbing its advantages over plurality using imprecise language to inflate or distort conclusions from the articles you cite Superb Owl (talk) 19:12, 30 August 2024 (UTC)
- I'm not particularly interested in trying to "equate" IRV with plurality or "scrubbing" anything off of any page. Describing two voting rules as being similar isn't violating NPOV if they're similar – both rules share a similar philosophy (based on counting how a single vote travels across candidates, with FPP being the case of a single round, 2RS two rounds, and IRV infinitely many). Both have similar end results (e.g. center squeeze). I'm still in the process of editing this and spoiler effect, which is why I'd agree with you that they're lacking some nuance right now. In particular, the similarity between FPP and IRV depends strongly on assumptions about voting behavior:
- If you have fully honest voting and a many-party system (like in the United Kingdom), the two rules behave very differently, and IRV substantially reduces the rate of spoiled elections and bias towards extreme candidates.
- If voters act strategically, or if you have a two-party system, IRV and FPP behave very similarly. This is because IRV simulates the effect of strategic voting on the outcome. A reasonable/basic model of FPP strategic voting would be "If I see a candidate in last place, I abandon them and support someone else to avoid wasting my vote." This produces the same end result as IRV.
- If there is already a first round of winnowing, e.g. by parties, the differences become substantially smaller, because the number of candidates shrinks so there's less opportunities for clones to crop up.
- I think all of these details should be reflected in the article, and I'm in the process of trying to integrate these. You're completely right that these articles are imperfect and don't reflect every nuance I've laid out above the way I'd like them to.
- If you have disagreements with the phrasing of this article or how precise it is, that's perfectly fine. I've leaned more towards WP:EVENTUALISM here, adding information I think is important and relevant before focusing on phrasing it perfectly.
- On the other hand, I'm not happy with the way this thread has devolved into personal attacks and accusations of bias, on the basis of an edit I think is a reasonable summary of the sources. If you disagree, that's ok, but focus on these specific disagreements. – Closed Limelike Curves (talk) 20:11, 30 August 2024 (UTC)
- Now the elephant in the room becomes more visible. If you are viewing everything only in terms of how it relates to a British parliamentary system where every district elects one representative from one party, then any distortions caused by the choice of voting system are going to be dwarfed by the choice of that political system. All systems have distortions; I am not saying the British parliamentary system is a bad choice, only that it is a specific application of voting that leads to specific desiderata. If you are going to use IRV in a very different context, for instance to determine the winner of a major annual artistic award, then the desiderata are going to be different. For instance, for the artistic award, a polarizing candidate might be a better choice (as judged by later historians of the subject) than a safe choice that nobody is excited by. For political leadership, the opposite might be true. What our article needs to do is, neutrally and based on good sources, to describe how different systems affect the outcome in different ways, without interpolating our own value judgements or parochial political concerns about those effects.—David Eppstein (talk) 20:50, 30 August 2024 (UTC)

- Not really interested into turning this into a "petty" fight :D Support for rules or "rankings" of rules is not really the output of research. While I agree that several people would probably prefer Condorcet rules to IRV, I know that this is (i) not true for all and (ii) not really something measurable or citeable one can or should put into the lead of this article. Further, in the paper you mentioned here, IRV is actually the second most approved rule, ahead of Copeland or range voting.

- Where did I describe any rounding method as being a bad method? – Closed Limelike Curves (talk) 19:18, 30 August 2024 (UTC)
- We could start with the phrasing "failure to use the correct rounding procedure" in one of the initially proposed hooks. Note the loaded words "failure" and "correct". —David Eppstein (talk) 19:28, 30 August 2024 (UTC)
- And as I repeatedly clarified, "correct" meant "the one enshrined into the law". I quickly edited it to remove that once you pointed out I'd made a mistake, and it was Hamilton's rule (rather than Webster's) that had been enshrined in law. – Closed Limelike Curves (talk) 20:13, 30 August 2024 (UTC)

- @Closed Limelike Curves I did an exhaustive cleanup of the body of the text - anything with a flag on it will be removed in a week if still there. If you want to help improve this article we really need consensus in the body before we touch the lead. I agree the lead needs to explain the downsides but also the upsides and we can't know how much weight to give each until the body has reliable sourcing and has been worked on by multiple editors Superb Owl (talk) 17:41, 2 September 2024 (UTC)

Mention of mathematical properties in article
(cc @Jannikp97, @Jasavina, and @CRGreathouse for comment as regular electoral systems article contributors)
I understand there's some questions about the precise phrasing, but I think my most recent attempt at the lead provided a decent, well-sourced summary of mathematical properties and research covered in this article. There's certainly some room for improvement, but I doubt this merited a complete reversion. WP:SUMMARYSTYLE mandates a lead should cover all the major topics of the article, and a discussion of the mathematical properties of RCV-IRV is definitely a major part of this article and important enough to get coverage. The properties I discussed here are the same ones discussed in basically every Wiki article on voting systems. These include IIA, independence of clones, monotonicity, participation, and Condorcet.
@Superb Owl's most recent edit went substantially further:
- In some cases, removing claims because one of several sources was less-than-perfect (e.g. newspaper articles or press releases by social choice theorists), despite the same claim also being sourced by stronger citations to scholarly journals. Citations that are not "load bearing" (i.e. included only for additional explanation or clarification) do not weaken the overall strength of sourcing for the claim. If a claim has multiple citations (some good and some bad), you can arguably remove the less-solid citations, but not the claim itself.
- The summary of empirical research by political scientists, including the comprehensive report of the Electoral Reform Research Group that got no pushback when it was only in the body and not the lead, has been deleted.
The combined effect of these changes is to push any on the pros and cons of IRV deep into the bottom of the article, where readers won't find it. – Closed Limelike Curves (talk) 17:40, 2 September 2024 (UTC)
- My issues are 1) You do not write in a way that is easily understood by a lay reader. It is too technical and makes things more confusing. Maybe some other editors can help explain what you are trying to do in a more accessible way. You also have 25% authorship of this article and it could really use fresh eyes and perspectives to make it understandable to a wider audience. 2) You seem to be cherry-picking studies and conclusions by primary sources for the lead are also disputed by reliable secondary sources in the body. You also make claims that are not WP:Verifiable or are WP:Synthesis. There needs to be nuance even if your positions against IRV are most likely to be the most common among experts. 3) The body of the article was a complete disaster and I spent an hour or two cleaning it up just now. The best way to know what to put in the lead is to have a body that is well-developed with solid sourcing. Superb Owl (talk) 17:47, 2 September 2024 (UTC)
- I'm not seeing any cases where the material in the lead is contradicted by a reliable secondary source in the body.
- There seem to be a few situations where the material in the lead contradicts commentary by non-reliable or partisan sources in the body (e.g. FairVote), but in this case the body should be edited to remove material supported only by unreliable sources. Published scholarly articles are substantially more reliable than press releases put out by advocacy groups for a particular policy.
- The lead relies heavily on secondary sources, including review articles (e.g. the ERRG report summarizing all the empirical research on this topic) and review/summary sections taken from papers in social choice.
- In cases where individual studies are cited, I make sure to include multiple such studies to show I'm not cherry-picking. You can read the summary sections of these articles if you'd like, which include an overview of the whole topic; there's no substantial dispute about any of the mathematical or statistical properties I'm bringing up.
- I'm happy to add any positive findings you can find by social choice theorists in peer-reviewed social choice journals. If you think there's positive aspects or studies on IRV that I'm not discussing, you're free to look those up and show it, but excluding all discussion of pros and cons simply because the majority of research has found isn't nuance, it's WP:FALSEBALANCE and failing to give WP:DUE weight. So far as I can tell, the properties I've surveyed are widely-studied, discussed in many papers, and are discussed in every Wikipedia article on voting systems (including this one).
- – Closed Limelike Curves (talk) 18:24, 2 September 2024 (UTC)
- Let's hear what others have to say. Your edits have been controversial to say the least on a number of related articles Superb Owl (talk) 18:43, 2 September 2024 (UTC)
- I'm not seeing any cases where the material in the lead is contradicted by a reliable secondary source in the body.
- A few thoughts, though admittedly I haven't done a close read of everything yet (and I'm just looking at the current state, not actually examining the changes). I also haven't evaluated what is sourced or evaluated whether the sources or adequate.
- Language is too technical in some places. "Pathology" "Partial results exist" are a few that jumped out right away.
- There seems to be a good bit of redundancy.
- The "Comparison to other voting systems" section seems to be better placed on a different page, such as ranked voting since only one row is actually about IRV.
- The information in the IRV row of "Comparisons to other voting systems" seems to be redundant with the "Voting Methods Criteria". Perhaps just keep the IRV row of the table, and get rid of the Criteria section? Anything from the criteria section that needs to stay could probably be folded into the Properties, Advantages, Disadvantages section.
- It seemed weird to have a Criteria section separate from a Properties. It also seems weird to have a Comparison to other systems section and a Similar Methods section.
- The last two paragraphs of the "Process" section seem to be criticisms and belong in a different section.
- Hopefully this "drive by commentary" is more helpful than annoying. meamemg (talk) 19:47, 3 September 2024 (UTC)
RFC: Title Change
I feel like the title change from Instant-Runoff to Ranked-Choice is very US-centric. I propose we revert it and have a discussion about what the title should be.
How do you tag the request for comment thingy? I would imagine other people would want to have a say. Jasavina (talk) 19:46, 17 October 2024 (UTC)
- you are correct. the title should not have been changed; this edit should certainly be reverted. Affinepplan (talk) 20:51, 17 October 2024 (UTC)
- Hi Jasavina—I recognize the issues, and I originally opposed switching the name. I only changed my mind very recently. There's three big reasons for this.
- Unfortunately, the old name (instant-runoff voting) is even more US-centric (which is also why this page is tagged as using American English, despite the mishmash of US+Commonwealth English in the text). Close to 100% of all searches for IRV come from the United States. In other countries, the rule is called STV (Ireland and India), preferential voting (Australia), or the alternative vote (UK), but it's never been called IRV. IRV has only ever been a popular term in the United States, where FairVote pushed the term up to 2015, but it hasn't stuck. IRV is therefore doubly-limited—it's specifically American, but it's also only used by a very small group of highly-educated millennials. RCV is more popular than IRV outside the US as well; it's now the dominant term in Canada and is occasionally used in Australia. In Commonwealth English overall, it's preferred over instant-runoff voting by a factor of 2:1.
- WP:COMMONNAME demands it, because the term IRV is essentially as dead as "majority preferential voting" (old term from the US prior to the 1970s). Until very recently, I didn't realize just how much RCV outstrips IRV in terms of popularity, but Google says searches for RCV are >100× more common than searches for IRV worldwide. (Actually, IRV doesn't even show up on trends. It just gets rounded to 0.)
- Many people conflate or confuse RCV with ranked voting, which is bad. I used to think we should "hold the line" on the name IRV because it's more descriptive and less confusing, and that the best way to do that would be to keep the title IRV. However, I've since changed my mind on this. I think the kind of people who are Googling or searching for "ranked-choice voting" are exactly the kind of people who need to read a Wikipedia article like this, which can explain the difference between RCV and ranked voting in general. I want people who look up RCV to land here, where it explains why RCV is better-called IRV and how there are ranked rules besides RCV; I don't want them to end up on lower-quality pages or advocacy groups that conflate the two. (Right now, the top results for RCV for me are from FairVote and RepresentUS. The Wikipedia article about ranked voting doesn't even appear on the first page of the results.)
- – Closed Limelike Curves (talk) 22:17, 17 October 2024 (UTC)
- An article with a title suggesting that it is about the many different ranked-choice voting systems should be about the many different ranked-choice voting systems. An article about a single system, instant-runoff voting, should have a title unambiguously specifying that it is about that single system. The recent move confuses this issue and should be reverted. The fact that many non-specialists are already confused about this issue should not be used as an excuse to make our articles and their titles equally confused. —David Eppstein (talk) 22:52, 17 October 2024 (UTC)
- 100% agree with reverting this move. One user who has a history of making controversial edits and ignoring any attempt to garner consensus doesn't get to decide on their own what this article is called. We don't name articles based on how they may or may not be ranked in search engines—that is clearly the cart before the horse. —Joeyconnick (talk) 00:38, 18 October 2024 (UTC)
- Hi Dr. Eppstein—even specialists (political scientists, legal scholars, and social choice theorists) use the same terminology. When I check the first two pages of search results for "ranked choice voting" on Google Scholar, all 20 results use the term to refer specifically to Hare's method. That's not to say nobody ever interprets the term literally, or that I don't dislike it as a misnomer (which is why I've retained the term IRV throughout the article). But I think the vast majority of users interpret the phrase "ranked choice voting" to mean something entirely different from the phrase "ranked voting", just like how Australians use the term "preferential voting" to specifically mean Hare's method. – Closed Limelike Curves (talk) 03:18, 18 October 2024 (UTC)
- The google trends results look very, very different the acronyms RCV, STV and IRV are actually included in the search. Doesn't seem like that is a solid basis. 180 Degree Open Angedre (talk) 02:40, 18 October 2024 (UTC)
- The acronyms "RCV", "STV", and "IRV" are all highly ambiguous because of how short they are. – Closed Limelike Curves (talk) 03:05, 18 October 2024 (UTC)

- I support reverting it back to instant run-off. The recent change in title just makes things more confusing. 180 Degree Open Angedre (talk) 02:27, 18 October 2024 (UTC)
- Support reverting to instant runoff. RCV article should be created, clarifying the term as a) ranked voting and why it is conflated b) explain that RCV became known primarily for IRV but also STV, an why, and that the reason that it is applied most commonly as single winner in the US. Similar problem to preferential voting and STV in Australia. I support creating more articles, I think the regional differences can warrant it as well as that it's sometimes just and overlap, not equivalence. Please ignore my username here, anyone from my edit history can see I am not biased in favour for RCV/IRV.
- IRV is not a perfect term (after all it can be confused with contingent voting), but more accurate than PV, RCV, AV and maybe even STV. I think if it is not the main term in any country, that is an advantage of neutrality. Unless we go for "Single winner repeated first-preference plurality loser elimination" or something, it is not going to be perfectly distinguishable. Rankedchoicevoter (talk) 08:14, 18 October 2024 (UTC)
- I support reverting the title back to instant-runoff voting. If "the kind of people who are Googling or searching for 'ranked-choice voting' are exactly the kind of people who need to read a Wikipedia article ... which can explain the difference between RCV and ranked voting in general", then that difference could be explained in the ranked voting article like David Eppstein suggests. Wotwotwoot (talk) 12:02, 18 October 2024 (UTC)
I have reverted the undiscussed move, since it's been at the old title for Quite Some Time. If you want to start a WP:Requested move discussion, go right ahead. --SarekOfVulcan (talk) 18:58, 18 October 2024 (UTC)
