MEN SMARTER THAN WOMEN; OFFICIAL Professor's claim after 100,000 tests.

Byline: By Natalie Walker

MEN are cleverer than women, according to scientific research.

That is why women have difficulty rising to the top of their careers, claims top psychologist John Philippe Rushton.

Professor Rushton claims the "glass ceiling" phenomenon is probably due to inferior intelligence rather than discrimination.

His team analysed 100,000 aptitude tests taken by 17 and 18-year-olds of both sexes.

Researchers focused on the general intelligence factor which relates to how quickly an individual can grasp a concept and is widely considered the most crucial ingredient for high IQ scores.

They discovered males scored an average of 3.63 IQ points higher than their female counterparts.

Women performed worse across every socio-economic level and across several ethnic groups.

Prof Rushton said men were more intelligent "throughout the entire distribution of scores, in every level of family income, for every level of fathers' and mothers' education and for each of seven ethnic groups", according to tests.

The findings overturn a 100-year consensus that men and women average the same in mental ability.

It also conflicts with evidence that girls do better in school exams than boys.

But Rushton, professor of psychology at the University of Western Ontario in Canada, said: "Up until late adolescence, the females have the advantage over males because they mature faster, which masks the underlying difference."

For decades, psychologists have accepted that men and women differ mentally, with males better in terms of "spatial ability" and females better on tests of "verbal ability".

But Prof Rushton said his results reinforce similar studies carried out by Richard Lynn at the University of Ulster and Helmut Nyborg at Aarhus University in Denmark.

He admitted his research had come up with "unpopular conclusions".

But he added: "People should not be made to feel afraid to study controversial issues.

"We have to find the truth about the normal distribution in society."
