I briefly noted this study yesterday, but now W. D. Craft analyzes it in great detail:
I am pessimistic that the authors’ more careful conclusions and recommendations will be noticed. Instead I fear we’re in for more naive calls for “abstinence education” and coerced virginity pledges.
Those who don’t want to have sex less likely to have sex. News at 11.
Really, the notion that you can identify people with “characteristics indicating an inclination to pledge initiate intercourse” who actually won’t make such a pledge is pretty silly. If they really had such an inclination they’d do it.
