Study: Expectations matter when it comes to math - CNN.com: WASHINGTON (AP) -- Telling women they can't do well in math may turn out be a self-fulfilling statement.
In tests in Canada, women who were told that men and women do math equally well did much better than those who were told there is a genetic difference in math ability.
And women who heard there were differences caused by environment -- such as math teachers giving more attention to boys -- outperformed those who were simply reminded they were females.
The women who did better in the tests got nearly twice as many right answers as those in the other groups, explained Steven J. Heine, a psychology professor at the University of British Columbia in Vancouver.
Expectations, it turns out, really do make a difference.
'The findings suggest that people tend to accept genetic explanations as if they're more powerful or irrevocable, which can lead to self-fulfilling prophecies,' said Heine.
The math study is the latest since Harvard University's president ignited controversy last year by suggesting that innate gender differences may partly explain why fewer women than men reach top university science jobs. The comment eventually cost him his job.
