Disgust sensitivity differs among men and women, and this phenomenon has been observed across numerous cultures. It remains unknown why such sex differences occur, but one of the reasons may relate to differences in self-presentation. We tested that hypothesis in an experiment comprising 299 participants (49% women) randomly allocated into three groups. Each group completed the Three Domains Disgust Scale (TDDS) and rated how disgusting they found olfactory, visual, gustatory, and tactile disgust elicitors either when a male experimenter was present, a female experimenter was present, or no experimenter was present. We hypothesised that male participants in the female experimenter group would declare decreased levels of disgust sensitivity, and female participants in the male experimenter group would declare increased levels of disgust sensitivity. Results showed that despite sex differences in pathogen and sexual disgust, attractive experimenters did not evoke any differences in declared disgust across groups with one exception–both men and women self-presented as more sensitive to sexual disgust in the presence of the female experimenter. We discuss our findings in the light of evolutionary and social theories.

“我可以向你介绍：我的厌恶！” – 在有吸引力的模特面前宣布厌恶敏感

男性和女性的厌恶敏感度不同，这种现象在许多文化中都有观察到。目前尚不清楚为什么会出现这种性别差异，但原因之一可能与自我表现的差异有关。我们在一项包含 299 名参与者（49% 女性）的实验中检验了该假设，该参与者随机分为三组。每组都完成了三域厌恶量表 (TDDS)，并评估了当男性实验者在场、女性实验者在场或没有实验者在场时，他们发现嗅觉、视觉、味觉和触觉厌恶诱发剂的厌恶程度。我们假设女性实验组的男性参与者会宣布厌恶敏感度降低，而男性实验组的女性参与者会宣布厌恶敏感度增加。结果表明，尽管在病原体和性厌恶方面存在性别差异，但有吸引力的实验者并没有在不同组之间引起任何明显的厌恶差异，只有一个例外——在女性实验者在场的情况下，男性和女性都自我表现出对性厌恶更敏感。我们根据进化和社会理论讨论我们的发现。
