Determining Bias from News Sources

In a perfect world, news or the reporting of current events would be presented as unbiased and fact based. In reality, many news sources are biased with either a liberal or conservative slant. When reading news in print or online, it can be difficult to determine if a media source leans in a certain direction (left/liberal or right/conservative) or is neutral and balanced.

Ad Fontes Media is an organization that rates the bias and reliability of various news sources with analysts using a specific methodology. View the most up-to-date Interactive Media Bias Chart. Once on the platform, look for a specific news source by name in the search box on the left. Example searches: Honolulu Star-Advertiser or Honolulu Civil Beat.  

Watch the video below as it explains how the chart came about and how it works. It does not depict the most recent chart.
