The thing that got me is that I'm in grad school (molecular biology) right now, and science is about writing at least as much as it's about math. Even the math-intensive students I know have got to have excellent verbal skills to give talks, write papers, and get any kind of funding. So even if it's true that women are better at words than math, which is inadequately proven to say the least, since when are words not a prerequisite for scientific success?
