Adherence to religious belief may serve to promote group cohesion and cooperation by decreasing the costs associated with social exchange. Consistent with this, organized religious ideologies, unlike secular or spiritual based ideologies, have been argued to facilitate cooperation among individuals living in large-scale societies. In the current study, we examined whether hypothetical adults’ explanations of natural events focused on religious ideologies were more effective at eliciting positive-affect compared to spiritual or natural explanations. Results revealed that religious cues were more effective (...) than spiritual cues in eliciting perceptions of positive-affect, but only when participant religiosity was taken into account. Participants high in religiosity favored the religious cues over the spiritual and natural cues, whereas participants high in spirituality showed no preferences. Conversely, participants low in religious belief demonstrated not only a positive bias towards the natural explanations, but also rated the adults expressing the supernatural explanations, in particular the religious explanations, as having greater negative-affect. From an evolutionary perspective, we interpreted the results as providing support that some forms of supernatural thinking, typical of organized religion, are more effective at eliciting feelings of positive and negative affect compared to supernatural beliefs not rooted in organized religion.
