You would think that people with a history of discrimination in the work place might give those whom they resemble a break, but a growing body of research confirms exactly the opposite: women are just as likely as men to show sexism toward other women in hiring practices, salaries, and professional mentorship. One study even found that people of both genders would forgo thousands of dollars in salary to have a male boss.
Overt displays of sexism of the bottom-pinching variety are largely passé in the American workplace. What remains, unfortunately, is a set of subtler and more ingrained cognitive biases deeply rooted in our evolutionary and cultural past. Getting rid of them will require an honest reckoning with the inalienable fact that humans are primed to make implicit errors in perception, and even ‘good’ people who actively eschew bias may nonetheless harbor subtle, yet damaging, stereotypes of which they are unaware.
In one of the latest studies, a psychology experiment published in the Proceedings of the National Academy of Science (PNAS), senior science faculty across the country were presented with identical resumes for a lab manager job (a position that can often lead to graduate study) that differed only by the gender of the hypothetical applicant. The resume raters were statistically more likely to rate the male candidate higher on competence and “hirability” and were also more likely to offer the male candidate a bigger salary and greater professional mentorship. (By contrast, the hypothetical female applicants were rated more “likeable” but less hirable.) The women scientists were just as likely to favor male candidates as potential hires as the male scientists…
