The AllSides Fact Check Bias Chart™ reveals the media bias of top fact checkers, such as Snopes, Politifact, and more.

The AllSides Fact Check Bias Chart™ is a companion to the AllSides Media Bias Chart™, which helps you to easily identify different perspectives so you can get the full picture and think for yourself.

Fact check websites like Snopes and Politifact reveal their bias numerous ways. Often, fact checkers will analyze information for the reader and draw a conclusion about the meaning of the facts, 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.

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

Knowing the political bias of media outlets and fact checkers allows you to consume a balanced news diet and avoid manipulation, misinformation and fake news. Everyone is biased, but hidden bias misleads and divides us. Our chart helps to free you from filter bubbles so you can get multiple perspectives, know more, and think for yourself. AllSides has rated the media bias of hundreds of sources, fact checkers and writers.

Unless otherwise noted, AllSides rates only online fact checking content, not TV, radio, or broadcast content.

How does AllSides rate fact checker bias? 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.

The AllSides Facts and Fact Checking Portal allows you to compare fact checks across the political spectrum. Learn how AllSides handles bias in fact checking.
