Against my better judgment, I'll comment in this thread.

I think the mistake in the post above is saying that physical strength has not been an issue for a millennia.

The strong have been using the threat of physical violence to take power right up to and including today. In the home, at work, and in society at large.

To put it bluntly, men are dumber. They're wired for task-to-task thinking, and their purposes are heavily motivated by challenges.

Women, by contrast, are wired for safety, which is a far more holistic approach to purpose because they consider connections men wouldn't even _consider_.

The downside of being smarter, though, is more unease about things you see that may present as a risk. It keeps females away from the bottom of the performance bell curve (men rank lowest in most metrics), but also from the top (men rank highest as well).

All of it is reprogrammable by operant conditioning (a large part of it often happening within marriage), but those are the biological primitives.

That’s not what’s being said here at all. As has been said in multiple comments pregnancy and everything associated with it physically and biologically is the most likely factor. It’s not bigoted to point out that women are biologically different in ways that make them unlikely to be rulers.
