Wikipedia exhibits a **mild to moderate left-wing bias** in its English-language content, according to recent studies. A 2024 Manhattan Institute analysis found that Wikipedia articles tend to associate right-of-center public figures with more negative sentiment and left-of-center figures with more positive emotions like joy[1][2][3]. This bias appears in articles on recent U.S. presidents, senators, Supreme Court justices, and Western prime ministers, among others[1][3].
Earlier research also showed Wikipedia articles on U.S. politics leaned pro-Democratic by favoring terms associated with Democrats over Republicans[1][2]. Wikipedia’s arbitration and enforcement processes have demonstrated institutional favoritism toward left-of-center views as well[1][2].
However, some research and reports suggest that this political bias is not uniform, with certain topics or groups showing no bias or even slight bias against the left[1][2]. Wikipedia’s content overall, however, is often found comparable in neutrality and accuracy to traditional encyclopedias like Britannica[1][4].
Wikipedia co-founder Larry Sanger has publicly stated he believes Wikipedia has a significant left-leaning ideological bias, especially as it has moved away from strict neutrality[1][3]. Media and commentators have noted that this leftward bias in Wikipedia can influence large AI models trained on its content, spreading the bias further[3].
In summary, expert analyses and researcher consensus indicate that Wikipedia’s content shows a **left-wing bias**, especially in political topics related to U.S. and Western politics, although it is described as moderate rather than extreme[1][3][4].
