TIM GROSECLOSE, a professor of political science and economics at the University of California, Los Angeles, constructs precise quantitative measures of the slant of television, radio, and print media. He estimates the SQ (slant quotient) of various news outlets. In his book, "Left Turn: How Liberal Media Bias Distorts the American Mind," Groseclose reports the results of his research, including: (1) that nearly all mainstream media outlets have a liberal bias; (2) that many so-called conservative outlets are in fact less tilted toward the right than the typical mainstream outlet is tilted toward the left; and (3) the bias has shifted the average American’s PQ (political quotient) significantly to the left.
