"Our country has a lot of stereotypes that boys are better than girls at math, and we have current evidence that both teachers and parents think that that's true," said Hyde. "But the data don't show that at all -- at least with these very current samples."

The article read Hyde's research team looked at gender differences at the highest levels of mathematical ability, and also tried to compare how well both girls and boys fared on questions requiring complex problem solving skills.  In both instances, the study found little difference between the sexes.

The article also said women in science and engineering often blame their low numbers on society factors. Young women receive little encouragement, and few role models are available for them.

"I'm hoping that parents and teachers see this study and say, 'Gosh, what I've been thinking  about boys being better at math, maybe it's not true," said Hyde. " I mean the data just don't show that's true -- so maybe people will revise their ideas."
