I KNEW IT!!!!!!!!!!!!
A study to be published later this year in the British Journal of Psychology says that men are on average five points ahead on IQ tests.
Paul Irwing and Professor Richard Lynn claim the difference grows when the highest IQ levels are considered.
Their research was based on IQ tests given to 80,000 people and a further study of 20,000 students.
Dr Irwing, a senior lecturer in organisational psychology at Manchester University, told the Today programme on BBC Radio Four the study showed 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," he said.
"This is against a background of women dramatically overtaking men in educational attainment and making very rapid advances in terms of occupational achievement."
The academics used a test which is said to measure "general cognitive ability" - spatial and verbal ability.
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.
