Bloggers and journalists have enjoyed reporting the findings of a recent study that showed that people in socially conservative states subscribe to online pornography websites at a higher rate than people in socially liberal states.  Here is some of the data from the paper:

The paper goes on to discuss what variables are correlated with higher versus lower subscription rates, but ultimately concludes:

On the whole, these adult entertainment subscription patterns show a remarkable consistency: all but eleven states have betweeen two and three subscribers to this service per thousand broadband households, and all but four have between 1.5 and 3.5.  With interest in online adult entertainment relatively constant across regions, there’s little sign of  a major divide.

The reporting on this study, which emphasizes the findings, but not the low variance, is a nice illustration of how studies can be warped when they are picked up by both journalists and bloggers.
