*Deconfounding Sex and Sex of Partner in Mate-Preference Research
通过分别分析双性恋和异性恋样本，发现择偶偏好的性别差异主要由参与者自身性别驱动，但男女都对男性伴侣的特质要求更高，说明择偶心理受自身性别和评估对象性别共同影响。
Much of the previous research examining sex differences in human mate preferences has relied exclusively on heterosexual participants. Consequently, prior work overlooks a critical limitation: In heterosexual populations, participant sex and partner sex are perfectly confounded. Here, we tease apart this fundamental problem by separately examining ideal preferences for male and female partners across two studies—one using a large bisexual sample ( n = 442) and another using a sample of both bisexual and heterosexual participants ( n = 380). The results revealed that sex differences in mate preferences were largely driven by the participants’ own sex. However, both males and females set higher standards overall for the traits of male partners. These findings suggest that a person’s mate-preference psychology is shaped by both one’s own sex and the sex of the target being evaluated. More broadly, these results expand our understanding of the proximate psychology underlying human mate preferences.
