Left Turn: How Liberal Media Bias Distorts the American Mind

A leading political science professor provides scientific proof of media bias in this sure-to-be-controversial book

Dr. Tim Groseclose, a professor of political science and economics at UCLA, has spent years constructing precise, quantitative measures of the slant of media outlets. He does this by measuring the political content of news, as a way to measure the PQ, or ＂political quotient＂ of voters and politicians.

Among his conclusions are: (i) all mainstream media outlets have a liberal bias; and (ii) while some supposedly conservative outlets--such the Washington Times or Fox News’ Special Report--do lean right, their conservative bias is less than the liberal bias of most mainstream outlets.

Groseclose contends that the general leftward bias of the media has shifted the PQ of the average American by about 20 points, on a scale of 100, the difference between the current political views of the average American, and the political views of the average resident of Orange County, California or Salt Lake County, Utah. With Left Turn readers can easily calculate their own PQ--to decide for themselves if the bias exists. This timely, much-needed study brings fact to this often overheated debate.

TIM GROSECLOSE is the Marvin Hoffenberg Professor of American Politics at UCLA. He has joint appointments in the political science and economics departments. He has held previous faculty appointments at Caltech, Stanford University, Ohio State University, Harvard University, and Carnegie Mellon University
