Washington (AP) -- Mathematic ability may be just a state of mind.
Canadian researchers say women who are told that men and women have equal math abilities get more right answers than women who are told there's a genetic difference.
And women who heard there are differences caused by environment, like math teachers giving more attention to boys, outperformed those who were reminded only that they are females.
A University of British Columbia psychology professor says the findings suggest genetic explanations can be a powerful influence, and can lead to "self-fulfilling prophecies."
A Harvard University president lost his job after he suggested last year that innate gender differences could help explain why fewer women get to the top in university science jobs.
