A new study has claimed that men really are more intelligent than women . The study concluded that men’s IQs are almost four points higher than women’s.
British-born researcher John Philippe Rushton says the finding could explain why so few women make it to the top in the workplace.
The Oxford University reached his conclusion after Scrutinizing the results of university ability tests taken by 100,000 students aged 17 and 18 of both sexes.
A focus on the factors such as the ability to quickly grasp a complex concept , verbal reasoning skills(语言推理能力) and creativity—some of the key factors of intelligence ---showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100 . The findings , which held true for all classes and levels of education , overturn 100-year opinion that men and women average the same in general mental ability. They also conflict（冲突） with evidence that girls do better in school exams than boys.
But Professor Rushton argues that the faster maturing（成熟） of girls leads to them outshining boys in the classroom .
