John Bohannon in Science Now: Both Genders Think Women Are Bad at Basic Math.

Study participants of both genders were divided into two groups: employers and job candidates.

And sometimes, after the employers made their hiring decision, they had a chance to change their minds after they were told by a researcher how the candidates had actually performed on a test run of the math sprint.

Men and women employers alike revealed their prejudice against women for a perceived lack of mathematical ability. When the only information that the employers had was a photograph of the candidate, men were twice as likely to be hired for the simple math job, no matter whether it was a man or woman doing the hiring [...]
