Collaboration on contested or slanted content The implication, per the authors, is that "many contributions are needed to reduce considerable bias and slant to something close to neutral". They further found that "he difference in bias between a pair of articles decreases with more revisions" and, when articles were substantially revised, the difference in bias compared to Britannica was statistically negligible. Entries about immigration trended toward Republican. The authors found that "Wikipedia articles are more slanted towards Democratic views than are Britannica articles, as well as more biased", particularly those focusing on civil rights, corporations, and government.

Evidence from Encyclopedia Britannica and Wikipedia (2018), Greenstein and Zhu directly compare about 4,000 articles related to U.S. They suggest that articles did not change their bias significantly due to revision, but rather that over time newer articles containing opposite points of view were responsible for centering the average overall. The authors concluded that older articles from the early years of Wikipedia leaned Democratic, whereas those created more recently held more balance. Congress and this lean rating is assigned to a Wikipedia contribution that includes the same key phrase. Each phrase is assigned a slant index based on how often it is used by Democratic vs.

In Is Wikipedia Biased? (2012), the authors examined a sample of 28,382 articles related to U.S. politics and the editors that work on them to identify aspects of ideological bias within its collective intelligence.

Wikipedia has an internal policy which states that articles must be written from a neutral point of view, which means representing fairly, proportionately, and, as far as possible, without editorial bias, all of the significant points of view that have been verifiably published by reliable sources on a topic. Questions relate to whether its content is biased due to the political, religious, or other ideology of its volunteer editors, and the effects this may have on the encyclopedia's reliability.
