The probability of being gay increases 33% with each older brother. It's a startling finding. https://www.pnas.org/content/115/2/234 https://www.pnas.org/conte

  Yeah, it's astounding. I thought about mentioning that, since it's another piece of evidence for the Lady Gaga thesis, especially with the NLGN4Y antibody mechanism evidence. But it seemed like weaker evidence than the infant-reassignment-surgery thing, which is pretty conclusive, and my comment was already far too long for the kind of person who needs this stuff explained to them. (Similarly with the prenatal SDN size stuff.) I mean, boys with just four older brothers are also growing up in a pretty different environment from firstborn boys or boys with just four older sisters. Just because this would be precisely the opposite environmental effect that conventional postnatal environmental theories of homosexuality predict doesn't mean there's no postnatal environmental effect.
