February 2020 Blind Bias Survey
During an AllSides Blind Bias Survey, participants from all sides of the political spectrum are asked to rate the content of a media outlet blindly, so they are not influenced by preconceived notions of a brand's bias.
For this survey, AllSides collected two types of content from media outlets: top headlines from two different days at the same time of day, and top stories the outlet ran around two major national news stories. Stories and headlines were stripped of branding and any information that would allow participants to identify the outlet. Participants were asked to rate the bias of the source on a scale of Left, Lean Left, Center, Lean Right, and Right.
Media outlets evaluated for bias in the February 2020 blind bias survey were:
A total of 1,877 people took the survey — 260 participants with a self-reported Left bias; 530 with a Lean Left bias; 506 with a Center bias; 442 with a Lean Right bias, and 139 with a Right bias.
AllSides uses multiple methods for calculating media bias ratings.
Our blind bias survey, described in the graphic below, represents our most robust media bias rating method, but it is not the only method we use. A source might openly share its bias, or it may be determined by third party research, an independent review, or an editorial review. Take a look at the multiple methods AllSides uses to measure and rate media bias.
