You may have seen reports on a study from Indiana University concluding that the mainstream media is biased—in favor of the Republican Party. (Yes, really.)

But according to Copious Dissent, there are severe problems in the study’s methodology: Analysis of the Indiana University Study on Republican Media Bias.

Overall, this study did not find statistically significant evidence to support the vast majority of the claims made by the authors. Some statistically significant data even contradict the authors’ claims. In fact, the editorializing conducted in Chapter 5’s discussion section goes so far outside the four corners of the study that it borders on pure advocacy. As a result, most if not all of the headlines seen around the Internet and on Television based on this study have no merit whatsoever.
