Why not "hard wired into women" rather than men when there is research indicating that women are "hard wired" to be more disgusted by potential sources of food contamination than men are, possibly for self and species preservation because it is women who get pregnant?
Not so different anymore? Women's and men's disgust sensitivity becomes similar with increasing age
15 May 2025
Highlights
• Young women report higher levels of disgust (& related variables) than young men.
• Differences regarding disgust are smaller/nonexistent among older men and women.
• Disgust sensitivity of men increases over time.
Abstract
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.
3.3. Conclusion
The present research provides evidence that women of childbearing age experience higher levels of disgust sensitivity and of other related variables than men. Moreover, the data shows that the differences between men and women diminish or even vanish in older age groups. In previous research, the increased female sensitivity was often explained by pointing to the likelihood of a potential pregnancy 14]. Our research contributes new indirect support for this reasoning by providing evidence that sex differences fade away with age (as the likelihood of pregnancy declines).

IMHO an over-reliance on social constructionism in feminism, and concomitant horror of any interpretation that might be construed as "biological essentialism", can lead us to underplay the significance of biological differences between the sexes.
In this instance, if all women of child-bearing age were provided with sufficient money to pay high wages to male cleaners then maybe a different pattern would emerge. However, if "disgust sensitivity" sex difference is real then could monetary reward ever result in males as a group becoming "hard wired that x chores must be done daily and weekly"?
I rather wish that I was MORE "hard wired that x chores must be done daily and weekly" as it would be far less disruptive than relying on periodic house-cleaning blitzes. That said, I am definitely conscious that it is my "disgust sensitivity" that hard-wires me to keep everything to do with food storage, food preparation and eating hygienic and bathroom and toilets clean 100% of the time with no lapses.
Other people, men and women, might be more or less "hard wired" and there will be individual differences in ability to express any "hard wiring" in action. However, if there appear to be sex-based differences then ideological acceptance that these must be due solely to societal pressures or influences can blind us to other possibilities.
Maybe there are differences between societies or periods of history that suggest "disgust sensitivity" differences and how these manifest are culturally bound rather than "hard wired"? However, the paper linked provides a plausible explanation that they are instincts linked to the possibility of pregnancy and child rearing.
It makes me wonder if the "disgust sensitivity" of women of child-bearing age but with little or no chance of becoming pregnant is more similar to other women the same age or to post-menopausal women? Either possibility would be open to interpretation, it just struck me that they are a distinct cohort buried in the "child bearing age" data.
