According to scientists we all have one - a real-life 'moral compass' in the brain which controls how we judge other people's behaviour. Researchers were able to use powerful magnets to disrupt this area of the brain and make people temporarily less moral.
One of my readers definition of Gordon Brown's brain: "His big clunking fist is magnetic and each time he scratches his ear, he scrambles his brain and his compass resets".
As good a definition as any isn't it!
For those of us with a 'slow mind' the news is good. We may nurture more creative ideas.
