"Yes, Wikipedia is often accused of having a left-leaning or liberal political bias, which has been the subject of public criticism and academic analysis. "

A 2023 study compared articles on controversial topics across multiple community-managed wikis: the study intended to test whether the policy orientation of a collaborative wiki project would produce a slant in the content, by selecting the crowd of contributors. The findings showed that the content of wikis with explicit ideological biases, such as RationalWiki and Conservapedia, is more unbalanced than that of wikis (such as Wikipedia) or encyclopedias (such as Encyclopedia Britannica) advocating neutrality. Wikipedia's content had no significantly bigger slant than that of Britannica, while both RationalWiki and Conservapedia were "more loaded with moral content".[14]
A 2024 study by David Rozado of the Manhattan Institute observed that Wikipedia had a liberal bias and expressed concern that "some of the politically biased sentiment associations embedded in Wikipedia articles also pop up in OpenAI’s language models".[15][16]
