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.

…Dr Irwing, a senior lecturer in organisational psychology at Manchester University, told the Today programme on BBC Radio Four that up until the age of 14, the study showed 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.
