Interactive Media Bias Chart by Ad Fontes Media
Methods: "... overall news source scores based on scores of individual articles (in the case of online news sources) or episodes (in the cases of podcasts, radio, TV, and video-based sources).
Each individual article and episode is rated by at least three human analysts with balanced right, left, and center self-reported political viewpoints. That is, at least one person who has rated the article self-identifies as being right-leaning, one as center, and one as left-leaning. Articles and episodes are rated in three-person live panels conducted in shifts over Zoom. Analysts first read each article and rate them on their own, then immediately compare scores. If there are discrepancies in the scores, they discuss and adjust scores if necessary. The three analysts’ ratings are averaged to produce the overall article rating. Sometimes articles are rated by larger panels of analysts for various reasons–for example, if there are outlier scores, the article may be rated by more than three analysts." --- ad fontes media
