In all seriousness, your question seems to come from a biological perspective, and that might have _some_ influence, but culture is likely to be a far larger factor.

As an aside, I feel like people think they are some sort of genius when they say “there are scientifically proven biological differences between the sexes!!!” and that is true, but culture tends to have a far larger impact.

Culture isn’t static either, in Western culture, with it’s focus on both progress / “rationality” as well as spiritualness, gender traits tend to go through periods of convergence and divergence. Right now we are at the peak of gender roles convergence, and we’ll probably see divergence over the next few years (as social programs finally improve one parent, presumably women, will find it easier to stay home), and then again convergence later on.
