The findings, reported in Psychological Science, were intriguing and unexpected. It’s known that people are more fearful of “out-groups” – that is, people who are different from them, and this fear of “the other” has been clearly demonstrated with race. But Navarrete found that volunteers’ most persistent fears were reserved for men – that is, male members of the out-group. So white men and women feared black men, and black men and women feared white men; all the other lab-induced fears, including any conditioned fear of women diminished.
