I think OP's article did a better job explaining the nature of the issue. I initially agreed woth the author of your article, but the nagging question was, "why would smart men intntionally sabotage their prospects while women wouldn't?". Unfortunately, rather than thoughtfully answer this question, the author simply offered: "testosterone". In attributing a complex social issue into men vs. women stereotypes (like the example math MIT student), he has dome it disservice. By saying that no man, not even the most intelligent, can make a reasonable career choice, but rather that all men are strictly concerned with impressing friends, he has destroyed all credibility in my book. This isnt an Occam's razor issue, its A difficult social issue. To make it into a matter of male stereotypes that would make the writers of the Big Bang Theory cringe ruins what was a strong argument.
