The report by the WJC is:The English-language version of Wikipedia hosted anti-Israel bias that perpetuated misinformation and negative stereotypes, according to a report by the World Jewish Congress (WJC) published on Tuesday.
The report said that the bias appeared in the form of terminology, the way issues and conflicts had been framed and failed to provide context in articles. These issues were particularly identified among articles published since the start of the Israel-Hamas war, the report said.
The WJC analysis of Wikipedia articles was carried out in partnership with Memetica. It was based on research, content analysis, and interviews with Israeli Wikipedia volunteer editors.
