Homosexuality and IQ: Looking at educational data in a post last year, I showed that men who report exclusively homosexual sex have above average years of schooling. I'm not sure why, but let's take a look at IQ data from the General Social Survey and look at a broader range of sexual orientations (I've limited the analysis to whites since sample sizes are too small for blacks):

Mean IQ

Gay men 104.8
Bisexual men 98.0
Straight men 100.0
Lesbians 102.2
Bisexual women 99.3
Straight women 101.3

First, gay men and lesbians have the highest numbers. In the earlier comments, someone made the reasonable speculation that smart people are simply more likely to admit they are homosexual. (Keep in mind they are simply asked about sexual behavior, not orientation). But shouldn't the numbers also be high for bisexuals as well? They are not. Perhaps smarter people also have the courage and decisiveness to make a clean break from heterosexual behavior? Or, are gay men and lesbians really smarter for someone unknown reason? They seem smart to me.
