"Why can't a woman be more like a man?" . . . and Vice Versa?

In My Fair Lady, Professor Higgins asks, "Why can't a woman be more like a man?"

The BBC's Science & Nature web page says, "Some researchers say that men can have 'women's brains' and that women can think more like men." And the BBC invites you to learn more about brain sex differences by taking their online Sex ID test, designed to test whether your brain is more typically male or female.

We scored a zero on the quiz. No, that score doesn't mean we failed the Sex ID test; it just means our brain is exactly halfway between male and female.
