I found this point interesting in the article:
Benbow and Lubinski also found something else intriguing: Women who are mathematically gifted are more likely than men to have strong verbal abilities as well; men who excel in math, by contrast, don't do nearly as well in verbal skills. As a result, the career choices for math-precocious women are wider than for their male counterparts. They can become scientists, but can succeed just as well as lawyers or teachers. With this range of choice, their data show, highly qualified women may opt out of certain technical or scientific jobs simply because they can.
So men who are skilled at math may have less flexibility to branch out and go into other areas that involve dealing with others. If women must be equal in terms of pursuing hard sciences, wouldn't it also be fair that men should have to be equal to women in terms of verbal skills so that they too, could have more job flexibility?
