The Essential Difference: Men, Women and the Extreme Male Brain by Simon Baron-Cohen
Simon Baron-Cohen shows that, indisputably, on average male and female minds are of a slightly different character. Men tend to be better at analysing systems (better systemisers), while women tend to be better at reading the emotions of other people (better empathisers). Baron-Cohen shows that this distinction arises from biology, not culture. He also introduces the extreme male brain theory of autism.
