Just some of my reactions to the 60 Minutes segment on sexual orientation. This is addressed to an assistant to the segment's producer who invited me to respond.
In the piece, this narration was near the end:
"Then there's the question of how something in the womb could affect one twin but not the other. There are many more questions at this point than answers, but the scientists 60 Minutes spoke to are increasingly convinced that genes, hormones, or both — that something is happening to determine sexual orientation before birth."
There are many problems with the segment but this narration reveals the crux of the matter. You acknowledge there are many more questions than answers, but you still reference your experts as having the conclusion that sexual orientation is determined before birth. You documented numerous exceptions to the theories you presented and then you make a conclusion that is unwarranted by that information. Given those exceptions, you could just as easily have concluded that the certainty that many people used to feel about sexual orientation being inborn might be misguided. In fact, we do not know why people experience the sexual attractions they do.
In fact, in this body of research, there is a relationship between gender non-conformity and later homosexuality but there are numerous exceptions (some effeminate men are straight and some masculine men are gay). However, while gender non-conformity is associated with genetic similarity, sexual orientation is not strongly correlated with being genetically alike. Bailey's own work shows this. There is a role for the environment to play in the pathway from gender nonconformity to sexual feelings. Your broadcast did not address how gender nonconformity might lead to homosexuality. It was just assumed that gender nonconformity was a precursor to homosexuality. In the process, you reinforced all of the stereotypes about gay men being effeminate and helped to reinforce the social environment that assumes effeminate boys will become gay. You could just as easily presented effeminate straight males and asked why they are straight if being gender nonconforming causes homosexuality.
The problem here is you assumed correlation means cause. A correlation between gender nonconformity and homosexuality does not warrant a conclusion that gender nonconformity directly causes homosexuality. A plausible explanation, at least for some gay men, is that the environment mediates in some way which effeminate men will become gay and which ones will not. In fact, a theory exists that suggests just this kind of mediation but it was not mentioned. Daryl Bem at Cornell has developed such a theory and it was irresponsible for you to discuss gender nonconformity without presenting Bem's work. In my opinion, you incorrectly led your viewers to believe that no credible science supports social environmental factors which might mediate the development of sexual attractions.
