Innate biological differences between men and women exist and are shaped by evolution, meaning each sex excels at different tasks.

“it is expected that there are many things on which men and women are the same. some things that men do better than women, some things that women do better than men. It's called evolution. It's called biology.”

Biological sex, fundamentally defined by investment in offspring through gamete size, shapes behavior and psychology across the biological ladder.

“the foundation of all reliably occurring sex differences in all sexually reproducing species are these small differences and this doesn't seem like it would be that big of a deal like wow like your sex cells are smaller than my sex cells like who cares but that actually turns out to be completel”

He claims that sex differences in human nature are empirical realities grounded in evolutionary biology that should be confronted rather than denied.

“we're better off confronting our nature and the empirical reality including sex differences in that nature rather than just pretending that these features don't exist”
