There are so many kinds of smart and so many kinds of stupid. And maybe certain kinds of smart and stupid are more common in men and certain kinds are more common in women.
In most species males and females have different roles as a result of natural selection. There is absolutely no reason to think that humans are any different.
In some species, males spend a lot of time trying to attract mates where females spend a lot of time caring for offspring. Those males don’t do that because they’ve come up with logical reasons for it. And the females aren’t thinking, “why does Jim get to fly around strutting his stuff all day while I’m stuck at home slaving over these screeching brats?” They do their thing because that’s what their instincts tell them to do.
I’m not saying that these are the roles that humans naturally have, and I’m definitely not saying that humans need to behave this way. My point is that nature gave male humans and female humans different roles. And nature did that by giving the male of the species different instincts than the female of the species. Male brains work a little differently from female brains, because those differences were selected by nature for optimal survival of the species.
No matter how much some of us would like there to be no difference between our brains, that just isn’t the case. None of this is to say that we can’t have a society that gives males and females equal opportunity or equal treatment. We can and, in my opinion, we should.
While men and women in general are different, it’s not a binary situation, and there is some overlap. So we can’t judge any individual by their sex. But we can generalize. And, if we want to understand the human condition, I think we must.
