This chart does not rate accuracy or credibility. A fact checker can be accurate, yet biased. Learn why AllSides doesn't rate accuracy.

Unless otherwise noted, these bias ratings are based on online, written fact checking content, not TV or radio content.

How can Fact Checkers be biased?

Fact check websites like Snopes and Politifact reveal their bias in numerous ways. These sources may be seen as more reliable or credible than other news outlets because of their focus on "facts." But often, fact checkers will analyze information for the reader and draw a conclusion about what the facts mean, which is subjective in nature. Other times, they’ll display bias based on what facts they choose to downplay or to highlight. They also show bias based on story choice — for example, primarily fact checking left-wing politicians, or only fact checking right-wing claims.

How does AllSides rate the bias of fact checkers?

AllSides uses multipartisan, scientific analysis to rate bias. Our methodology is scientific, but each individual will have a subjective opinion of the bias of any given outlet. We reflect the average view of Americans, not one individual.

We use multiple methods to rate media bias, including Editorial Reviews, Blind Bias Surveys, independent reviews, and third party research.

Some of the sources included on the AllSides Fact Check Bias Chart™ are dedicated fact checking websites that stand alone (such as Snopes or Others are fact checking sections embedded within a larger media outlet (such as Reuters, AP or The New York Times). We assess the bias of fact check sections separately from the rest of the source’s content.
