Not so different anymore? Women's and men's disgust sensitivity becomes similar with increasing age

Previous research provides ample evidence that women experience more disgust than men. The most prominent explanation for these effects is that women are more careful and sensitive about their health due to the possibility of harming potential offspring. Given that the probability for women to give birth is decreasing after a certain age (i.e., menopause), we assume that differences between men and women might be smaller or even faded away over time. To test this hypothesis, we revisited several data sets (in total N = 28′059) containing information about sex, age, and variables related to disgust. The predicted pattern was found for food disgust sensitivity, food neophobia, health-wise worries about food, and contamination fear. In all presented studies, the scores of younger women were higher compared to those of younger males, but after a certain age, sex differences were less pronounced or even non-existent. We discuss how considering the factor age together with individuals sex helps us to gain more insight in the dynamics of disgust and vulnerability.
