Virginity Pledges

From a story by Elizabeth Mehren in the LA Times:

Virginity pledges, in which young people vow to abstain from sex until marriage, have little staying power among those who take them, a Harvard study has found. More than half of the adolescents who make the signed public promises give up on their pledges within a year, according to the study released last week... "The Harvard report is wrong," said Janice Crouse, a fellow at a Concerned Women for America think tank. "This study is in direct contradiction with trends we have been seeing in recent years," Crouse said. "Those who make virginity pledges have shown greater resolve to save sex for marriage." [The Harvard study also found that]...of those who had sex after telling the first interviewers they had taken the pledge, 73% denied in the second interview having made the pledge.
