The study you read about in the newspaper telling you that men are better at reading maps or parking than women, for example, may be entirely contradicted by another study on a different population, in which women happen to be better map-readers or parkers. The beautiful brain scan is not the photograph of our thoughts that it claims to be. And in some branches of science, such as evolutionary psychology, theories may be little more than thin scraps of unreliable evidence strung into a narrative.
