Don't tell the folks at Harvard, but there do seem to be brain differences between men and women (although the fact that I like Aqua Teen Hunger Force and my wife thinks it's the dumbest thing on the planet was proof enough for me).

This Scientific American article lays a lot of the existing evidence on the table. No proof that women can't do math or science, but that wasn't what Larry Summers suggested anyway.

Maybe what Larry proved is that, in the minds of many, economists (and especially university presidents who are economists) are only supposed to talk about GDP, unemployment, and trade balances.
