>But that's not the case for nursing. So why do men get promoted over women?
Hard to say as I know very little about these fields. Presumably people in these fields are promoted because they show leadership or managerial qualities of some sort. Is there a reason to expect leadership or managerial qualities, or the interest in positions with those responsibilities to be unequally distributed among the sexes? Maybe. The differences in assertiveness is one potential explanation. Also the differences in status-seeking behavior. I'm not saying these differences explain it, but they're potential causes that can't be ruled out from the data alone.
