@SwipeWright @DanJanini @WSJ @FondOfBeetles This is relying on Aristotelian definitions too much: by this standard, no one is going to be strictly homo- or heterosexual, because it's possible in principle for their brain's "attractiveness function" to be "fooled" by sufficiently well-passing transsexuals.

@wanyeburkett I agree that heritability is real and important, but pro sport families don't seem like a compelling example. The environmentalist theory is "the father coached the kids from early on in a family that obsessively values the sport" not just "hung around in the dugout."
