Outside observers (who did not know the purpose of the study) coded the video recordings and assigned each woman a “bitchy” score (i.e., level of indirect aggression displayed). The women who were exposed to the woman in sexy attire were rated as bitchier than that those who saw the conservatively dressed woman.
Another group of heterosexual women rated photos of the same woman wearing either her sexy or conservative attire. Women who saw photographs of the woman in a provocative outfit (versus the conservative outfit) said they would be less likely to be friends with her, introduce her to their boyfriends, or allow her to spend time alone with their boyfriends.
Why would women have a more negative reaction to the sexy vs. conservative woman? Evolutionary theory suggests that disparaging sexy and attractive women and not allowing your partner to spend time with such women is a form of intrasexual competition (e.g., mate guarding or keeping your partner’s attention on you).
Perhaps the women on The Bachelor this season are just following their instincts.
