Sociopolitical attitudes are often the root cause of conflicts between individuals, groups, and even nations, but little is known about the origin of individual differences in sociopolitical orientation. We test a combination of economic and evolutionary ideas about the degree to which the mating market, sex, age, and income affect sociopolitical orientation. We collected data online through Amazon’s Mechanical Turk from 1108 US participants who were between 18 and 60, fluent in English, and single. While ostensibly testing a new online dating website, participants created an online dating profile and described people they would like to date. We manipulated the participants’ popularity in the mating market and the size of the market (i.e., the number of ideal partners in the market) and then measured participants’ sociopolitical attitudes. The sociopolitical attitudes were reduced to five dimensions via Principal Components Analysis (Sociosexuality, Benevolent Sexism, Wealth Redistribution, Nonconforming Behaviors, and Traditional Family Values). Both manipulations affected attitudes toward wealth redistribution but were largely not significant predictors of the other dimensions. Men reported more unrestricted sociosexual attitudes, and more support for benevolent sexism and traditional family values, than women did, and women supported wealth redistribution more than men did. There was no sex difference in accepting nonconforming behaviors. Younger people and people with lower incomes were more liberal than older people and people with higher incomes, respectively, regardless of sex. Overall, effects were largely not interactive, suggesting that individual differences in sociopolitical orientation may reflect strategic self-interest and be more straightforward than previously predicted.

交配市场，性别，年龄和收入对社会政治取向的影响：来自进化论和性经济学理论的见解。

社会政治态度通常是个人，群体乃至国家之间发生冲突的根本原因，但人们对社会政治取向上个体差异的成因知之甚少。我们测试了关于交配市场，性别，年龄和收入在多大程度上影响社会政治取向的经济和进化观念的组合。我们通过Amazon's Mechanical Turk在线收集了来自1108名18至60岁，英语流利且单身的美国参与者的数据。在表面上测试一个新的在线约会网站时，参与者创建了一个在线约会个人资料并描述了他们想要约会的人。我们操纵了参与者在交配市场中的知名度和市场规模（即市场中理想合作伙伴的数量），然后测量了参与者的社会政治态度。通过主成分分析（社会性别，仁慈的性别歧视，财富再分配，不合规行为和传统家庭价值观）将社会政治态度减少到五个维度。两种操纵都影响了人们对财富再分配的态度，但在很大程度上并不是其他维度的重要预测因素。与女性相比，男性报告了更多不受限制的社会性态度，以及对仁慈的性别歧视和传统家庭价值观的更多支持，而女性对财富再分配的支持比男性更多。接受不合格行为没有性别差异。不论性别，年轻人和收入较低的人分别比老年人和收入较高的人更为自由。总体而言，效果在很大程度上不是互动的，
