I came across someone linking this on Twitter, claiming that people should make sure to get a balanced media diet, based on the categories they have places media in.
I think you have to be fairly rightwinged to think this is a fair representation of the media landscape in the US. Most of the news sources mentioned in “Lean Right” should be in the “Right” column, most of the “Lean Left” and even “Left” should be “Center”.
AllSides claim that the analysis is scientific, but when you read their description, you realize that they are anything but scientific, but entirely dependent on self-assessment and group evaluations, without clear definitions.
Rather than being a fair rating of news sources, this is probably an attempt to normalize right-winged media, claiming that they are as close to the center as major mainstream news sources like New York Times and the Economist.
My suggestion for a balanced and mostly true news media, is to look at the Left, Lean Left, and Center columns, and make sure to read from several sources there. Then look at the Lean Right and Right columns, and make sure to avoid those sources.
