Wikipedia is the world's encyclopedia, the first result for almost everything. On Israel, it has a bias problem, and that is not a conspiracy theory. Wikipedia's own court said so.
For most people, Wikipedia is the record: the top search result, the answer the AI assistants quote. Which is why who edits it matters. In 2025, both the Anti-Defamation League and Wikipedia's own arbitration committee documented something specific and serious on the Israel-Palestine articles: not honest disagreement, but a coordinated campaign to bend the record. Here is what they found.
In March 2025, the ADL published an investigation finding a network of roughly 30 editors working in concert to skew Israel-Palestine coverage. They made about twice as many edits as comparable editors and communicated with one another up to 18 times more. The pattern, intensifying after October 7, was consistent: strip out sourced material on Palestinian terrorism, antisemitism and calls to destroy Israel, while amplifying criticism of Israel and voting in tandem to make it stick.
This is the part that lifts it above accusation. In February 2025, Wikipedia's Arbitration Committee, the platform's internal court, topic-banned eight editors from the Israel-Palestine area and tightened the rules to stop further distortion. To its credit, the committee sanctioned both sides: six editors from the pro-Palestinian camp and two from the pro-Israel one. But the finding stands on the record: the bending of these pages was real enough that Wikipedia itself moved to stop it. A US Congressional inquiry into foreign involvement followed.
In the same stretch, Wikipedia's editors voted to treat the ADL itself as an unreliable source on the Israeli-Palestinian conflict, downgrading one of the world's foremost monitors of antisemitism on the very topic where it was sounding the alarm. Whatever one thinks of the ADL, the timing tells its own story: the referee was thrown out of the game it was refereeing.
