Past research has shown that humans possess implicit or unconscious associations which, when activated, affect subsequent behavior. In three studies, I demonstrated a novel implicit association held by some men, an association between women and birds. In Study 1, I provided initial evidence of a Women-Bird association and its autonomy from other common prejudice measures. In Study 2, I demonstrated two consequences for possessing a Women-Bird association: increased sexist hiring decisions and increased dehumanization of women. For my third study, I demonstrated a causal pattern, such that activation of the Women-Bird association caused an increase in dehumanization of women, sexist hiring decisions, and perceptions that a female candidate was incompetent for those who possessed the association. Mediation analysis indicated that activation of the Women-Bird association among those who possessed the association resulted in sexist hiring decisions because these participants perceived the female candidate as less competent. These findings provide insight into a cause of bias toward women that should be accounted for when attempting to reduce discrimination toward women.
