Sit down for a moment. Relax. Then clasp your hands together so your fingers entwine — don’t overthink it! Now look at your thumbs. Which one is on top — the left one or the right?
If you are a man, the odds are it will be the left; if you are a woman, it is more likely to be the right. Now unfold your hands and take a look at your fingers, in particular your index finger (next to your thumb) and your ring finger (next to your little finger).

Strangely enough, your hands give clues to what is sometimes called ‘brain sex’ — the way your brain reflects your gender.
Of course, we all have different skills and interests, but some are considered more typically male, and occur more commonly in men, while others are described as more typically female, and occur more commonly in women.[amazon asin=031623480X&template=*lrc ad (right)]
According to popular mythology, men tend to be more obsessed by things such as cars and obscure facts. You find men in pubs discussing the top speed of a car they are never going to drive, let alone own. They cling to the TV remote control. They like spending time in sheds.
Women, on the other hand, are said to be better at empathy and understanding what another person is feeling or needs. In an emotional crisis, they are more likely to offer sympathy.

This is the stuff of jokes and self-help books — but it is also shown to be true through science. The question is, do these tendencies result from nature — with the biological gender we are born with deciding our interests and personalities — or do they result from nurture, with society and upbringing creating the differing ways that men and women behave?
The BBC series Horizon asked Professor Alice Roberts and me to investigate. We started from very different positions.[amazon asin=B00FOVLXYW&template=*lrc ad (right)]
Alice thinks apparent brain differences between the sexes have been exaggerated by how our culture treats boys and girls. In the programme she carries out fascinating tests to prove her point, such as dressing up little boys as girls and vice versa and watching how people treat them.
Almost immediately, the girls start rough-housing and playing with trucks, while the boys are treated far more gently by the adults around them.
She argues that parents’ unconscious actions — such as being gentler with girls and letting boys behave more roughly — often mould children into men and women who embody gender stereotypes.
