Sure, it's partly inertia, I agree. But you haven't presented any evidence that instincts aren't playing a part as well. Granted, neither have I, but it's pretty clear how sexual selection has wired us over time. I don't think people are hardwired to view men as leaders, but people are hardwired to view men more favourably when they exhibit ambition. This makes it more difficult for women to be ambitious and still come across well.
I don't know why there's such a hang up on this. Is it such a problem to admit that people have instincts, and not everything is completely arbitrary and socially constructed?
I disagree. I don't think this is hardwiring. It's socially constructed and highly confining gender roles. It's because women with ambition have historically 9and still are) punished for being
unladylike. It's because socially we are
conditioned that females are quiet, polite, cooperative, and focus on putting other people's needs ahead of their own. Females are
taught to be supportive and to cede space to males, we are
taught that we are expected to always be nice and friendly and decorative. Males are conditioned to be boisterous, rambunctious, adventures risk takers. They are taught to be loud, to go after what they want, to speak their minds.
The differential treatment of children on the basis of sex based stereotypes are really strong.
A female child who plays in the mud and yells and runs a lot is much very likely to be told to calm down, to have her parents complain about her clothes getting dirty, and to be told that she's misbehaving. A male child doing the same thing is likely to be praised for being so active and adventurous, and dirty clothes are just "boys being boys". A girl child who is very vocal about what she wants is likely to be told that she's being selfish and to think about other people's needs too. A boy child doing the same thing is likely to get his wants met, and to be rewarded for speaking out. A boy child who takes control of his play group will be perceived as a "natural leader" and "charismatic" by adults. A girl child will be perceived as "pushy" and as not caring about the other kids' desires.
There's a flip side to that too, of course. Girls are allowed to cry and be sad, especially if it's empathy related. Boys are expected to "chin up" and not be a bay, they're expected to internalize their physical pain and "take it like a man". And they're discouraged from engaging in "girly" crafts like sewing and needlepoint and such.
The point here is that these behaviors are not inherent. They're taught to us as children, they're reflected in everything we see in fiction, on TV, and from adults. We're conditioned - through both positive and negative reinforcement - to conform with those stereotypes.
