Wheel rediscovered: "For centuries men believed themselves to be smarter than the fairer sex, who they felt were only equipped for wifely duties. Now a study has revealed that the male of the species is actually more intelligent. But there's a catch - he's also more stupid. When scientists measured the intelligence of more than 2500 brothers and sisters, they found a disproportionate number of men in both the top 2 per cent and the bottom 2 per cent. There were twice as many men as women in the smartest group. But there were also twice as many men among the dunces. The subjects were tested on science, maths, English and mechanical abilities. The average scores of the men were virtually identical to that of the women. Professor Bates, of Scotland's Edinburgh University, said: "The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground."
