Evolved mate preferences have taken center stage in evolutionary psychology research, yet this literature has been fairly muted on mate preferences for extrapair partners. Here, we examined the mate preferences for mistress relationships (the traits that men prioritize in a mistress and mistresses prioritize in their male partners) and compared these preferences to those of short- and long-term relationships.

情妇关系的长短：性别差异的择偶偏好反映了择偶理想的妥协

进化的择偶偏好已成为进化心理学研究的中心舞台，但该文献对异性伴侣的择偶偏好却相当冷淡。在这里，我们研究了情妇关系的择偶偏好（男人在情妇身上优先考虑的特征，而情妇在男性伴侣身上优先考虑的特征），并将这些偏好与短期和长期关系的偏好进行了比较。
