Do men and women have different standards of success?

This quote has been haunting me because it rings so true:

men tended to stick with their studies as long as they completed the coursework, while women did so only if they earned high grades

I don’t see that in all fields but I definitely see it in computer science. I wonder if it’s because only really competitive women tend to stick it out in a field that’s often less than 20% women (and comes with all the problems that entails.) They are used to working hard, competing and doing well. And when they don’t, well they figure they should be doing something else. Something they excel at.

I’ve seen it happen. (And for the record the women I know went on to be really successful in other scientific fields. I think they would have excelled in computer science too.)

What do you think?
