Zero information is preferred to misleading or false information

Originally by Jimmy Wales, 16 May 2006 (Source):

I can NOT emphasize this enough.

There seems to be a terrible bias among some editors that some sort of random speculative "I heard it somewhere" pseudo information is to be tagged with a "needs a cite" tag. Wrong. It should be removed, aggressively, unless it can be sourced. This is true of all information, but it is particularly true of negative information about living persons.

I think a fair number of people need to be kicked out of the project just for being lousy writers. (This is not a policy statement, just a statement of attitude and frustration.)

(my emphasis)

While the above quote was in the context of misleading information with respect to living people, I believe its a good principle for all articles.

Every Wikipedian should read Wikipedia:Verifiability.
