The AllSides Media Bias Rating reflects the average judgment of the American people.

The AllSides Media Bias RatingTM reflects the average judgment of the American people. We don't use a convoluted mathematical or artificial intelligence model, but instead have regular people representing the broad spectrum of Americans blindly rate the bias of articles. That produces a fair, verifiable bias rating.

This media bias rating was determined using the following levels of bias verification.

Basis of Rating:

Blind Survey
Third Party Data
Community Feedback
Editorial Review
Secondary Research

Confidence Level:

Low or Initial Rating

Unless otherwise noted, this bias rating refers only to news articles on their web site, not from opinion pieces or what is broadcasted on TV or radio. The opinion writers from the same media source may have different bias ratings, so individual writers often are rated separately.
