Abstract: Why do some people moralize overindulgence in inherently victimless bodily pleasures, such as gluttony, masturbation, drinking, or laziness, when these behaviors appear devoid of any harmful consequences to other people? We test the hypothesis that these moral judgements stem from perceptions that overindulgence alters people’s self-control, thus making them more likely to cheat in cooperative interactions. In an online experiment on 400 American adults, participants judged that a target who was caused to increase his indulgence in bodily pleasures would reduce his self-control and disposition to cooperate. Participants judged, by contrast, that sustained restraint from bodily pleasures over several months would improve a target’s self-control and disposition to cooperate. The effect of indulgence (vs. restraint) on perceived change in cooperativeness was fully mediated by perceived change in self-control. This supports the idea that bodily pleasures are perceived as increasing people’s propensity to cheat because they are perceived as reducing their self-control, which is perceived necessary for cooperative behavior. Finally, the more people perceived indulgence as reducing self-control and cooperativeness, the more they regarded indulgence in victimless bodily pleasures as morally wrong (e.g., masturbation, gluttony, harmless drinking and laziness). These results provide preliminary support for the Moral disciplining theory of puritanism, according to which, although inherently harmless, bodily pleasures are condemned as indirectly facilitating antisocial behaviors through their perceived effect on self-control.
