So, it seems this is old news, but somehow I missed it. I haven't looked at the actual study and have questions about whether they controlled for the prescence of situational pedophiles in their sample (if they didn't, then this study says more about people willing to have sex with children than it does about people attracted to them), but it's interesting nevertheless.
