Tem um comentário de uma pessoa aqui ,que diz que a maioria dos homossexuais foram abusados na infância, ele só esqueceu de pesquisar que também tem muitas pessoas que hoje héteros que foram também abusas.Tem muitos pedófilos que também foram abusados.Nada
ver ser homossexual com abuso sexual.Abuso sexual atinge qualquer classe social e sexual.

I’ve said it before, but it would be interesting to someday do a similar study involving heterosexuals. It would be MUCH for difficult, I think, to compensate for the social desirability factor though.

Marty asked in post 130187: why does a 20% prevalence automatically point to a genetic influence? Don’t twins almost always grow up in a remarkably similar environment? It is because they were raised in the same environment that the twin studies are important. Since the environments are similar, the significant variable becomes the genetics. So when you compare identical and non-identical twins and see a significantly higher concordance with the identical twins, then that suggests a genetic factor. It doesn't prove a genetic factor because there may be other variables involved. Further, the twins studies do show that it isn't only based on genetics, because then the concordance between identical twins would have been much, much higher.

Regarding the twins studies, i've often wondered -- why does a 20% prevalence automatically point to a genetic influence? Don't twins almost always grow up in a remarkably similar environment?
