Are there essential differences between the male and female brain? My theory is that the female brain is predominantly hard-wired for empathy, and that the male brain is predominantly hard-wired for understanding and building systems. I call it the empathising-systemising (E-S) theory.

So Russell has an extreme male brain. I decided to take the test and apparently I have a balanced brain – one that is equally systematic and empathising.
