except for the whole women are "not doctors" thing.

That depends on whether they go on to become doctors, veterinarians and dentists instead of assistants to those. The fact that someone has a certain education does not preclude them from ending up in a more assistive job related to the education. In fact, if women are still underrepresented among new doctors, veterinarians and dentists, that would be a likely explanation.

I don't think somebody studying medicine ends up being a nurse. Not the women mentioned here either. I suspect Stubbornella simply didn't check many numbers.

For example, maybe because a lot of women are working in people facing jobs (secretaries, receptionists), it distorts impressions. Meanwhile, the men are shoveling shit in the backyard. At the same time lots of men and women have "better" jobs, but they are not as visible. So the impression is "women tend to become receptionists".

Too bad there's no way we can find out. If we had some kind of a computer where we search for the answer, perhaps the confusion would subside.
