Pittsburgh Post-Gazette media bias rating is Center.

AllSides rates the Pittsburgh Post-Gazette's bias as Center. A Jan. 2022 Independent Review with reviewers on the left and right determined its news and opinion content did not match its previous Lean Right rating. The news section didn't display many of the types of media bias, and the opinion section displayed views from the center, right and left. Reviewers also noted the use of full quotes and lack of substantial tilt. The independent review was prompted in part by community feedback that disagreed with the previous rating. 

This AllSides Bias Rating™ is our low or initial rating, so more research and community feedback is needed. In the mid 1800s, the Gazette helped organize a chapter of the new Republican Party as well as helped with the election of President Abraham Lincoln. The Post-Gazette was one of the first papers to suggest that the Northern and Southern tensions would result in a full-scale war.
