Abstract

If recent reports in the media are anything to go by, we now know why some people crave chocolate, why teenagers tend to be moody and – most impressively of all, perhaps – which parties voters will opt for in elections. Findings like these, we are assured, have the backing of science. We owe them to advances in brain-scanning technology that have enabled researchers to pinpoint the brain's ‘pleasure centre’ or ‘thinking area’, and so to achieve mind-reading powers that have hitherto been the stuff of fantasy. There is even some site in the brain that might be called a ‘God spot’.
