AllSides recently conducted our April/May 2021 Blind Bias Survey, in which 1,455 people across the political spectrum blindly rated the bias of five media outlets: ABC News, USA Today, National Review, CBS News, and Reason.

The results confirmed our Lean Left ratings for ABC and CBC News, as well as our Lean Right rating for Reason magazine. Respondents rated National Review Lean Right on average, which differed from our rating of Right. On average, respondents rated USA TODAY Lean Left, which differed from our rating of Center.

The results triggered Editorial Reviews of USA Today and National Review. Editorial Reviews allow the AllSides team to review more content from outlets than a Blind Survey does. The USA TODAY review was inconclusive, so the Center rating remains; we will conduct further review soon. We opted to keep National Review rated as Right.

About the Survey

AllSides asked people across the political spectrum to identify their own personal political bias: Left, Lean Left, Center, Lean Right, or Right — using our Rate Your Bias tool. We then present them with 10 headlines from the outlet on two different days, and some coverage from the outlet of two major national news stories. We then ask them to provide an overall rating of the media outlet (Left, Lean Left, Center, Lean Right, or Right).

The content is stripped of any branding or information that would allow the participant to identify which publication the content came from. This ensures respondents’ pre-conceived notions of the outlet or brand don’t affect their ratings.

There is no "accurate" measure of bias – bias is largely in the eye of the beholder. What seems like a left-wing view to a right-winger may seem like a centrist view to a left-winger. That's why we survey Americans from across the country, of various ages, geographic locations, and political leanings. We also normalize the data and don’t let majority rule determine our ratings.
