Sexual orientation predicts women’s preferences for sexually dimorphic face-shape characteristics
Previous research has suggested that heterosexual women show stronger preferences for images of male faces displaying masculine shape characteristics than do homosexual women. Because many other findings regarding individual differences in women’s masculinity preferences have not replicated in subsequent studies, we carried out a direct replication of Glassenberg et al’s (2010) comparison of heterosexual and homosexual women’s preferences for sexually dimorphic face-shape characteristics. In common with Glassenberg et al., our replication study found that heterosexual women (N = 20,360) showed stronger preferences for masculine men that did homosexual women (N = 1598). This association between women’s sexual orientation and masculinity preferences is consistent with the proposal that heterosexual women’s masculinity preferences, at least partly, reflect hypothesized benefits to offspring fathered by masculine men. However, we also emphasize the importance of testing alternative explanations in future research, such as those that might stem from between-group differences in visual experience with different types of faces.
