Media Bias/Fact Check

Media Bias/Fact Check (MBFC) is a website founded in 2015 by editor Dave Van Zandt. The website has been described as an amateur effort to rate news media sources based on factual accuracy and political bias.
Methodology.
Sites are rated on a 0–10 scale by Van Zandt and his team using categories such as biased wording and headlines, factuality and sourcing, and story choices.
Reception.
The "Columbia Journalism Review" describes Media Bias/Fact Check as an amateur attempt at categorizing media bias and Van Zandt as an "armchair media analyst." The Poynter Institute notes, "Media Bias/Fact Check is a widely cited source for news stories and even studies about misinformation, despite the fact that its method is in no way scientific."
The site has been used by researchers at the University of Michigan to create a tool called the "Iffy Quotient", which draws data from "Media Bias/Fact Check" and "NewsWhip" to track the prevalence of "fake news" and questionable sources on social media. The site was also used by a research group at the Massachusetts Institute of Technology in initial training of an AI to fact check and detect the bias on a website.
