The AllSides Bias RatingTM reflects the average judgment of the American people.
Bias is normal. If you've got a pulse, you've got a bias. But hidden bias misleads and divides us. Please join us in making bias more transparent everywhere.
How AllSides Calculates Bias
AllSides is creating the world's most effective bias detection engine. It's powered by a combination of wisdom-of-the-crowd technology and the best statistical research and methodologies.
You drive the bias ratings.
What you do at AllSides affects our bias ratings. That includes how you rate your own bias and how you rate the bias of news sites, especially through our blind bias surveys. All of this is added to our crowd data, which is statistically normalized to represent a balance of the American public.
Our bias detection engine gets smarter as time goes on.
We are constantly evolving the bias engine. And, the more you participate, the better our ratings will be and the more sources we can rate. We also apply third party bias research to strengthen our results. Currently, we source our media ratings on a combination of our crowd-sourced data plus UCLA research by Tom Groseclose and Jeffrey Milyo.
We also ask you to rate your own bias. This keeps AllSides honest for all of us.
We're developing ways to help you get the most accurate bias self-rating so you can participate on AllSides with transparency. Make the world a better place by wearing your bias openly!
