No evidence that facial attractiveness, femininity, averageness, or coloration are valid health cues in young adult women

No evidence that facial attractiveness, femininity, averageness, or coloration are valid health cues in young adult women. Ziyi Cai et al. https://osf.io/f9tu2/

Description: Previous reports that women with attractive faces are healthier have been widely cited as evidence that sexual selection has shaped human mate preferences. However, evidence for correlations between women’s physical health and facial attractiveness is equivocal. Moreover, positive results on this issue have generally come from studies of self-reported health in small samples. The current study took standardized face photographs of women who completed three different health questionnaires (Ns=582, 583, 572). Of these women, 221 also provided a saliva sample that was assayed for immunoglobulin A (a marker of immune function). Analyses showed no significant correlations between rated facial attractiveness and either scores on any of the health questionnaires or salivary immunoglobulin A. Furthermore there was no compelling evidence that objective measures of sexual dimorphism of face shape, averageness of face shape, or facial coloration were correlated with health. These null results do not support the prominent and influential assumption that women’s facial attractiveness is a health cue, at least in young adult women.
