Shades of Gay: The heterogeneity of homosexuality.

William Saletan

Guy walks into a shrink's office. Says he's gay and wants to be straight. Shrink says, "OK, I'll help."
Don't wait for the punch line. There isn't one, because this isn't a joke. It's a true story. And it's a common one, according to a British study just published in BMC Psychiatry. Researchers contacted more than 1,800 mental health professionals to find out whether they would ever try to change a client's sexual orientation. Of the 1,328 practitioners who responded, one in six admitted to having helped at least one patient attempt to alter homosexual feelings. The total number of such cases reported by the respondents was 413. That's nearly one case for every three therapists.
