“In one test, Correll and her colleagues found that evaluators consistently ranked mothers as less competent and less committed workers than childless women but ranked fathers as more competent and committed than non-fathers. In a follow-up study, the researchers responded to more than 600 newspaper ads for high-level business positions by sending out fake resumes for two equally qualified candidates that varied only in very subtle references to parenting activities. They found that the childless female candidate was twice as likely to be called in for an interview as the mother. Fathers experienced no call-back penalty.”
