“A major new study reports that, up to the age of 14, there was no difference between the IQs of boys and girls. But beyond that age and into adulthood there is a difference of five points, which is small but it can have important implications. As intelligence scores among the study group rose, the academics say they found a widening gap between the sexes. There were twice as many men with IQ scores of 125, for example, a level said to correspond with people getting first-class degrees. At scores of 155, associated with genius, there were 5.5 men for every woman.”
