Sex, Lies, and Unfortunately No Videotape

Via Slate:

Teens who take virginity pledges can't be trusted, according to an analysis of follow-up surveys. Findings: 1) 52 percent of pledgers denied a year later that they'd pledged. 2) Among pledgers who later admitted to having sex the year after the pledge, 73 percent denied they'd pledged. 3) Among pledgers who conceded in the first survey that they'd had sex, nearly one in three claimed a year later that they'd never had sex. 4) Pledgers were four times as likely as non-pledgers to recant previous admissions that they'd had sex. Researchers' conclusions: 1) Teens lie. 2) Pledgers lie more. 3) Born-again pledgers (those who pledge after having sex) lie the most. 4) Pledges fail. 5) We have no idea what works or what the truth is, because all this revisionism makes the data worthless.

There is no doubt sex is a serious undertaking with many risks, but am I the only one that has a visceral hatred of the born-agains that try to influence kids to take this path and the self-righteous twits that agree to it?
