“The bottom line is that saying there are differences in male and female brains is just not true. There is pretty compelling evidence that any differences are tiny and are the result of environment not biology,” said Prof Rippon.
“You can’t pick up a brain and say ‘that’s a girls brain, or that’s a boys brain’ in the same way you can with the skeleton. They look the same.”
Prof Rippon points to earlier studies that showed the brains of London black cab drivers physically changed after they had acquired The Knowledge – an encyclopaedic recall of the capital’s streets.
She believes differences in male and female brains are due to similar cultural stimuli. A women’s brain may therefore become ‘wired’ for multi-tasking simply because society expects that of her and so she uses that part of her brain more often. The brain adapts in the same way as a muscle gets larger with extra use.
“What often isn’t picked up on is how plastic and permeable the brain is. It is changing throughout out lifetime
“The world is full of stereotypical attitudes and unconscious bias. It is full of the drip, drip, drip of the gendered environment.”
Prof Rippon believes that gender differences appear early in western societies and are based on traditional stereotypes of how boys and girls should behave and which toys they should play with.
