Attractive Female Romantic Partners Provide a Proxy for Unobservable Male Qualities

Abstract

Previous research indicates that women find men more desirable when they appear to be desired by other women than in the absence of such cues—an effect referred to as female mate choice copying. Female mate choice copying is believed to emerge from a process whereby women use the presence of a man’s mate as a cue to his own quality. Here, we test this hypothesis explicitly by examining whether the desirability enhancement effect conferred on men by the presumed interest of an attractive female (a) emerges only when the female is described as being a man’s current romantic partner (Experiment 1) and (b) is mediated by women’s belief that men partnered to attractive women possess unobservable qualities that women value in their romantic partners (Experiment 2). The results of our two experiments found support for these hypotheses, shedding new light on the processes influencing human female mate choice copying.
