> It's more like we have three "sex groups": all women, normal men and extreme outlier men.

For the sake of conversation, I think it's worth pointing out that we could actually break out yet another group: the extreme outlier men at the low end of the curve.

High male variance means men dominate at both ends of the distribution. This is why "incels" and such are almost exclusively a male group. These people not only lose the genetic lottery, they're then lumped in with the high end outliers demographically and systematically punished for "imbalances" when they're already less likely to win these winner-takes-all games than anyone else.
