University study shows liberal bias in media (although not as bad as I thought)

bah! the only evidence worth considering in this instance is empirical data, and the only empirical data (evidence) ever presented on this board is the groseclose/milyo study (twice!! with those presenting pretending they are separate studies.)

...Not that some on the right aren’t willing to try. Academics Tim Groseclose and Jeff Milyo got considerable attention for a paper they wrote called “A Measure of Media Bias” (12/04), which deduced a “strong liberal bias” from an analysis of news outlets’ use of “think tanks.” (The groups the study looks at are actually a combination of think tanks and advocacy groups.)

The report used a peculiar Rube Goldberg–like method to calculate media bias from think tank citations: Taking the Americans for Democratic Action ratings of congressional voting records as its yardstick, it assumed that media outlets have ideologies similar to those of members of Congress who cited the same think tanks that the media outlets did.

This approach is based on the problematic notion that politicians cite the think tanks that they most agree with rather than the ones whose citation will be the most politically effective—a problem the researchers acknowledge when they attempt to explain away some curious anomalies that their method produces. (The National Rifle Association comes out as a centrist group; the Rand Corporation turns out to be left-leaning.)

If the authors truly wanted to rank media outlets on the ADA scale, the simpler method would be to look at the ADA ratings of congressmembers quoted by those news outlets. One suspects that the authors avoided this obvious approach because the results would have been less to their liking: Studies in Extra! have repeatedly found various media outlets quote Republicans more often than Democrats, by ratios ranging from 3 to 2 on NPR (5–6/04) to 3 to 1 on nightly network news (5–6/02) to a startling 5 to 1 on Fox News’ Special Report (7–8/04). Fox News, according to Groseclose and Milyo’s method, is a “centrist” news outlet.
