I was surprised to see ifeminists.com linking to a study reported in the Journal of Human Sexuality, a journal apparently motivated by a “Christian biblical perspective,” and carried out by N.A.R.T.H., the National Association for Research and Therapy of Homosexuality, another admittedly conservative outfit.
This doesn’t necessarily mean the science behind the study is bogus, but as a heuristic device the confession of a Christian bias is a poor way to convey scientific credibility.
The study purports to show that therapy is successful in helping homosexuals overcome their same-sex attraction over the long term. Prominent gay activist Peter Tatchell believes homosexuals have a choice too - and they ought to embrace it! And in an interview here Steven Pinker states that only about 30-40% of the variance in sexual orientation can be explained by genetic predisposition.
