When does AllSides give a source a "Mixed" media bias rating?
If a source has a system for aggregating content that is openly and transparently designed to show multiple perspectives, and the content comes from sources that are left, center and right, we assign a Mixed bias rating.
This rating is given to sources that curate journalistic articles. This does not mean the source never misses or omits a perspective, or that it perfectly shows all possible perspectives. It does mean that the site is designed to show multiple perspectives.
