Evolutionary and sociocultural theories of mate selection preferences contend that men place greater value on physical attractiveness than do women. Thus, meta-analyses were conducted of findings from 5 research paradigms that have examined the hypothesis: (a) questionnaire studies, (b) analyses of lonely hearts advertisments, (c) studies that correlate attractiveness with opposite-sex popularity, (d) studies that correlate attractiveness with liking by a dyadic interaction partner, and (e) experiments that manipulate the attractiveness and similarity of an opposite-sex stranger. The anticipated sex difference emerged in all five meta-analyses, although it was larger in research that examined self-reports than in research that examined social behavior.
