Rand-y agenda clouds analysis

Racy Content on TV May Encourage Teen Sex
(washingtonpost.com):

"'This is the strongest evidence yet that the sexual content of television programs encourages adolescents to initiate sexual intercourse and other sexual activities,' said Rebecca Collins, a Rand Corp. psychologist who headed the study, published in the journal Pediatrics. "

This is from the Rand Corporation? And here I thought they were a well-respected think tank. Well, they lost a couple of points with ol' Kokopelli with that kind of poor analysis. Cruise around a college campus and you'll hear some geeky junior trying to bed a freshman by spouting "but that's a falacious post hoc ergo proctor hoc argument". Simply put, to assume that because one event happened after another does not necessarily mean there is a causal relationship.
I am not saying that excessive viewing of overly sexualized content on television is healthy for adolescents. I'm even quite willing to admit that there appears to be a correlation between the two. But that does not imply causality! It is just as likely, as I read this brief synopsis of the study, that those kids predisposed to early sexual experimentation are more likely to seek out sexually charged content on television.
This is simply poor science, apparently politically or personally motivated. We should expect better from one of our nation's top think tanks.
