Detecting Bias



NewsGuard is a browser extension created by NewsGuard Technologies. It rates news sources with either a green or red icon, which it calls "nutrition labels" indicating the news source's general trustworthiness and history of running stories labeled as fake news. Supported browsers include Google ChromeMicrosoft EdgeFirefox, and Safari. It is included by default in the mobile version of Edge, though users must enable it. 

In January 2020, NewsGuard began notifying users that it would become a paid, member-supported browser extension in early 2020, while remaining free to libraries and educators who become part of a proposed partnership. 

NewsGuard presents as a useful tool, albeit not free.
