A good test of a media outlet’s political bias is whether it is more concerned about right wing (red line) or left wing (blue line) extremism.
A new study by David Rozado and Erik Kaufman calculates the Concern Index for 44 US publications. Strikingly, purportedly mainstream publications like the Associated Press, Reuters, and the New York Times are almost as biased in absolute terms as explicitly leftist publications like The Nation.
CBS News is the least leftist biased of the three old broadcast news networks.
