Evolution is not relevant to sex differences in humans because I want it that way! Evidence for the politicization of human evolutionary psychology.
Glenn Geher & Daniel Gambacorta
This research explored political motivations underlying resistance to evolutionary psychology. Data were collected from 268 adults who varied in terms of academic employment and parental status. Dependent variables represented whether participants believed that several attributes are primarily the result of biological evolution versus socialization. Variables addressed attitudes about: (a) sex differences in adults, (b) sex differences in children, (c) sex differences in chickens, (d) human universals, and (e) differences between dogs and cats. Using a Likert-scale, participants were asked to rate the degree to which they believed items were due to “nature” versus “nurture.” For instance, one of the items from the cat/dog subscale was “Dogs are more pack-oriented than cats.” Independent variables included political orientation, parental status, and academic employment status. Political liberalism corresponded to endorsing “nurture” as influential – but primarily for the two human sex-difference variables. Academic employment status was independently predictive of the belief that sex differences are the result of “nurture.” This effect was exacerbated for academics who came from sociology or women’s studies backgrounds. The effect of academic employment status also corresponded to seeing behavioral differences between roosters and hens as caused by “nurture.” Further, parents were more likely than non-parents to endorse “nature” for the sex-difference variables. Beliefs about differences between cats and dogs and beliefs about causes of human universals (that are not tied to sex differences) were not related to these independent variables, suggesting that the political resistance to evolutionary psychology is specifically targeted at work on sex differences.
