In the current study, the author investigated whether sociosexual orientation interacted with an experimental manipulation of sex ratios previously used by Li et al. (2010) which showed that men and women report greater religiosity after viewing profiles of attractive members of their own sex. The author predicted that only people of restricted sociosexual orientation would be reporting greater religiosity after viewing profiles of attractive members of their own sex. A sample of 171 undergraduate students (85 men, Mage = 19.5) from a large Southwestern university participated in the study for course credit. Participants were first administered the Sociosexual Orientation Index (Simpson & Gangestad, 1991). Then, under the pretense of assisting psychology faculty in designing a dating website for incoming students, participants viewed a set of profiles (photo and description) of either attractive men or attractive women, after which they answered a series of questions on a religiosity scale developed for the current study. Results showed that sociosexual orientation did not interact significantly with the experimental manipulation. Additionally, the results of the current study failed to replicate those of Li et al. (2010). The author discusses possibilities for why the results of the current study failed to replicate the results of Li et al., and for alternative explanations of the potential role of sociosexual orientation in responding to shifting sex ratios.
