at the near-genius level (an IQ of 145), brilliant men outnumber brilliant women by 8 to one. That's statistics, not sexism.
In this context, Professor Greenfield's indignation that only one in ten science professors is female doesn't seem all that bad. It also goes some way to explaining why, in almost 110 years of Nobel Prize history, only two women have ever won the Prize for physics, only four have won the Prize for chemistry and why no women at all have ever won the coveted Fields Medal for mathematics in eight decades of trying.
It's sad that mentioning such simple facts makes one a sexist.
