Comscore Audience Reach MetricĬomscore’s Total Digital Population Data (provided by Comscore Multi Metrix (R), representing an unduplicated measure of digital audiences across desktop and mobile platforms) is viewable as a proportionally-sized bubble around each news/information source on the Media Bias Chart. The analysts’ scores are then averaged, and the average score is shown on the chart. Each of these ratings are on a numerical scale between -42 (left) and +42 (right). Each of these ratings are on a numerical scale between 0-64, with 0 being the least reliable and 64 being the most reliable.Įach analyst also rates each article on three individual bias sub-factors of 1) Language, 2) Political Position, and 3) Comparison, and then the analyst gives the article an “Overall” bias rating. ArticlesĮach analyst has gone through extensive training on Ad Fontes Media’s rating methodology, which is based on content analysis of articles.Įach analyst rates each article on three individual reliability sub-factors of 1) Expression, 2) Veracity, and 3) Headline/Graphic, and then the analyst gives the article an “Overall” reliability rating. Our weighting algorithm captures the effect that individual articles with low reliability or high bias have on overall perceptions of the news source. We rate all types of articles, including those labeled analysis or opinion by the news source, and the dominant factor for how we select articles from a page is prominence.Įach overall source score is a weighted average of the individual article scores. We typically have at least 15 articles rated per web source, but for larger sources (such as the New York Times and Washington Post) we have over 100 articles in our sample. Sometimes articles are rated by larger panels of analysts for various reasons.įor each news source, we pick a sample of articles that are most prominently featured on that source’s website over several news cycles. Each article is rated by at least three human analysts with balanced political viewpoints: one who self-identifies as right-leaning, one as center-leaning, and one as left-leaning. Overall news source scores are generated based on scores of individual articles. ![]() For more detail, please see our Methodology page.
