No matter how good the study, this man's career is over.
It is research that is guaranteed to delight men - and infuriate the women in their lives. A controversial new study has claimed that men really are more intelligent than women.
The study - carried out by a man - concluded that men's IQs are almost four points higher than women's.
British-born researcher John Philippe Rushton, who previously created a furore by suggesting intelligence is influenced by race, says the finding could explain why so few women make it to the top in the workplace.
He claims the 'glass ceiling' phenomenon is probably due to inferior intelligence, rather than discrimination or lack of opportunity.
The University of Western Ontario psychologist reached his conclusion after scrutinising the results of university aptitude tests taken by 100,000 students aged 17 and 18 of both sexes.
