I don't think this conflicts with the clip I put up last month, "Hmm: Internet porn prevents rapes" <http://clipmarks.com/clipmark/3999C606-AE68-4220-BC6D-28B84FD3B37C/>;. Two different groups of people. The general porn study was on the whole population. The child porn study was only on felons--and in my judgment, someone who's into child porn is a sicko to start with.

There's a lot not understood yet: "It is not at all clear when, or in whom, the viewing spurs action or activates a latent, unconscious desire; or whether such images have little or no effect on the offender’s subsequent behavior. But the relationship probably varies widely."
