“…First, insofar as morality is a potentially powerful constraint on sex buying, the theoretical models described in prior sex buying research may be incomplete. Second, research documents that moral beliefs differ across social and demographic groups (Graham et al, 2009(Graham et al, , 2011Miles, 2014), and are associated with attitudes regarding sexual permissiveness (Haidt & Hersh, 2001), rape myth acceptance (Barnett & Hilz, 2018;Gable et al, 2017), sexism (Vecina & Piñuela, 2017), and adherence to traditional gender roles (Graham et al, 2011). Thus, empirically, prior research focusing solely on demographic or genderbased explanations for sex buying may suffer from omitted variable bias and either overstate or understate the relationships between sex buying and other theoretically relevant variables.…”
