A chronological list of surveys and bias analysis conducted to determine AllSides Media Bias Ratings™. See which outlets recently underwent an AllSides Editorial Review, Blind Bias Survey, independent review, or other verification method.
During an AllSides Editorial Review, a panel of reviewers — which includes at least six people from the left, center, and right — reviews news reports from a source from the past six months to the present day, looks for types of media bias, deliberates, and comes to a general consensus on the source's bias. During a Small Group Editorial Review, a smaller panel of reviewers — one each from the left, center, and right — reviews and rates news content. Learn more about the Editorial Review process here.
An AllSides Independent Review is our lowest level of analysis. It is used to provide an initial bias rating with low confidence. An AllSides panelist reviews news reports from a source and comes to a conclusion on its bias. This method is used for initial bias ratings before more robust methods can be applied, or for outlets that are transparent about their bias and we agree with their assessment.
