Please read Cordelia Fine's Delusions of Gender, because it goes into exactly why things like this are bogus science.
While we're at it, lets go back to pi=3, like god intended.
Studies like the one in the article give us data points, but nowhere to draw any conclusions from.
Conclusions in things like this are very often 'just-so' stories, of the kind you hear from the Evo Psych nonsense-heads.
Almost every study purporting to show innate differences between males and females has been shown to lack rigor, blindness, or has drawn conclusions from imaginary sources based on pre-conceived notions not found in the data.
You can see those preconceived notions in this thread. Many of the comments have a very strong stench of "of course, we've known this all along, men and women are different, and it's unfortunate that only men are good at the things that pay a lot of money, but that's life". The latter part may not be stated directly, but anyone who has paid any attention to this kind of argument on the internet knows that it's heavily implied under a very thin surface in the majority of comments like this.
