Wikipedia's Biased Edits on Israel Remain Unchecked, ADL Report Finds

A new report by the Anti-Defamation League (ADL) reveals that allegedly biased edits concerning Israel, Hamas, and the war have largely gone uncorrected on Wikipedia. Despite the banning or removal of several editors involved in the issue, their work continues to influence the information millions of readers access daily.

The report, titled "Damage Done: Wikipedia Leaves Biased Edits Unchecked Despite Editor Bans," states that while overt coordination among problematic editors has decreased by approximately 95% following public criticism and pressure from U.S. lawmakers, a new group of 11 active accounts, along with eight veteran editors who faced no sanctions, now controls key edits. These editors employ more subtle methods, such as reverting changes to maintain a specific narrative, softening factual claims, and slowly rebuilding articles to avoid immediate community attention.

According to the findings, these new editors are responsible for about 60% of recent edits on 229 reviewed articles. This means that the content accessed by users, and subsequently fed into large language models and search engines, still bears the mark of a systematic disinformation campaign.

The ADL highlights specific examples of distorted content. The article on "Hamas" initially downplayed its status as a terror organization, with its designation appearing only at the end of the main paragraph, which received a million views daily after the October 7th attacks. The entry for "Zionism" described the movement's goals as achieved through "colonization" and claimed Zionists sought a state with "as few Palestinian Arabs as possible." Additionally, in articles discussing sexual violence on October 7th, editors framed accounts of sexual assault against Israeli women and girls as being "according to reports," a framing that persisted for three years despite official findings.

The ADL is urging the Wikimedia Foundation to implement structural changes, including requiring private identity verification for editors in controversial areas, halting anonymous edits via IP addresses on sensitive pages, resolving content disputes based on expertise rather than majority votes, and establishing a dedicated team to address antisemitic bias. The report also calls on search engines and AI companies to indicate when Wikipedia serves as a primary source for their information.
