-We can't talk about group differences, for fear that belief in differences will be abused to shore up oppression. But ... structural oppression and actual group differences can _both exist at the same time_. They're not contradicting each other! Like, the fact that men are physically stronger than women (on average, but the effect size is really big, like _d_ ≈ [TODO: size] for [TODO: operationalization]) is _not unrelated_ to the persistence of patriarchy! That doesn't mean patriarchy is good! [(You can't derive an _ought_ from an _is_.)](https://plato.stanford.edu/entries/hume-moral/#io) This is pretty obvious, really?
+We can't talk about group differences, for fear that anyone arguing that differences exist is just trying to shore up oppression. But ... structural oppression and actual group differences can _both exist at the same time_. They're not contradicting each other! Like, the fact that men are physically stronger than women (on average, but the effect size is really big, like _d_ ≈ 2.6 for total muscle mass) is _not unrelated_ to the persistence of patriarchy! That doesn't mean patriarchy is good; to think so would be to commit the naturalistic fallacy of [attempting to derive an _ought_ from an _is_](https://plato.stanford.edu/entries/hume-moral/#io). No one would say that famine and plague are good just because they, too, are subject to scientific explanation. This is pretty obvious, really? But similarly, genetically-mediated differences in cognitive repertoires between ancestral populations are probably going to be _part_ of the explanation for _why_ we see the particular forms of inequality and oppression that we do, just as a brute material fact devoid of any particular moral significance, like how part of the explanation for why European conquest of the Americas went smoother for the invaders than the colonization of Africa had to do with the disease burden going the other way (Native Americans were particularly vulnerable to smallpox, but Europeans were particularly vulnerable to malaria).
