Wikipedia Is Biased against Conservatives — and the Slant Is Infecting AI Models

A new study released on Thursday by a conservative think-tank is giving scholarly credibility to long-held conservative suspicions of bias among Wikipedia editors on entries related to current events. 

Wikipedia entries for conservative political figures and organizations do in fact contain more negative attitudes than entries for their liberal counterparts, according to a new Manhattan Institute report released Thursday. This bias could have profound implications for the training of large-language artificial intelligence models, according to the study’s author, David Rozado, a computer scientist who previously researched the apparent left-wing bias of artificial intelligence chatbot ChatGPT and other large-language models.
