But even Greenspan is prevented by polite convention from making the obvious point: women and men have different chromosomal structures, lifespans, organs, and hormone levels. There's also substantial evidence[1,2] that they differ in average levels of spatial, verbal, and mathematical reasoning ability (with women generally having an advantage in verbal and men in visuospatial/mathematical). We should not expect them to have the same outcomes on average.
Women also can only have at most 10-20 children over their lifespan, whereas men like Genghis Khan[3] can have a virtually unbounded number. This is why males have a greater evolutionary payoff for high-risk, high-reward behavior: intrinsically higher reproductive variance.
But hey. That's evolution, and even though it provides a consilient explanation for a variety of allied phenomena, everyone knows that doesn't and couldn't apply to human beings (we all well know what happens to people who propose that a behavior has genetic influences). It is instead easier to pretend that humans aren't biological creatures with hard biological constraints.
Yet if your premises are wrong, one is simply practicing fashionable creationism. And that is where we are today, presented with the spectacle of a privileged billionairess who lashes out at phantasms rather than wrestling with the realities of molecular biology. Why not lean in to a publication on behavioral neuroendocrinology, for a change?
