The Science of Sexual Orientation

Shaker DD passed on this article about a CBS special on the science of sexual orientation. It’s quite an interesting article, and I’m really just passing on the link so you can go read the whole thing and then discuss in comments.

One thing I actually found rather amusing (and terrifying) is something scientists call “the older brother effect”:

[F]or every older brother a man has, his chances of being gay increase by one third. Older sisters make no difference, and there's no corresponding effect for lesbians. A first-born son has about a 2 percent chance of being gay, and the numbers rise from there.

That means that families who have lots of children are most likely to end up with a gay son. And who has the most kids? Religious conservatives.

That’s right—I’m talking to you, Duggars.
