Abstract: Socio-political attitudes, such as preferring progressive or conservative social norms, markedly vary among individuals. Here we investigated whether these attitudes are influenced by the characteristics of the mating market one is engaged in. In two studies, we manipulated the attractiveness or income of same-sex competitors in an individual’s local mating market. In Study 1, a between-subjects design randomly allocated single participants (N = 151 women and 229 men) to experimental conditions where the same-sex peers in their local county were attractive, average-looking, or unattractive, or to a control group. In Study 2, a between-subjects design randomly allocated single participants (N = 173 women and 234 men) to experimental conditions where the same-sex peers in their local county had high incomes, average incomes, or low incomes, or again to a control group. Results showed that same-sex competitors’ attractiveness influenced women’s, but not men’s, attitudes concerning benevolent sexism and traditional family values. Same-sex competitors’ income affected both men’s attitudes towards wealth redistribution, and women’s attitudes towards traditional family values. We interpret these results in light of the costs and benefits of holding specific socio-political attitudes given the degree of romantic competition in the local mating market.
