Wikipedia as an anchor of truth
Wikipedia has been criticized as being inherently unreliable, and we ourselves warn users not to rely uncritically on the information in Wikipedia; it is ironic to see it now used as an anchor of truth in a seething sea of disinformation. AI models are prone to hallucinating, that is, giving false answers with confidence and corroborative detail to things that simply are untrue. Can using Wikipedia help to at least spot these mistakes, and are the new search engine AIs using them in ways that will actually help prevent hallucination?
