Housework and motherhood aren’t the only things affecting gender balance. There’s outright sexism, too. In a study published in 2012, psychologist Corinne Moss-Racusin and a team of researchers at Yale University explored the possibility of gender bias in recruitment by sending out fake job applications for a vacancy of laboratory manager. Every application was identical except that half were given a female name and half a male name. When they were asked to comment on these potential employees, scientists rated women significantly lower in competence and hireability.
