Natural and supernatural explanations are used to interpret the same events in a number of predictable and universal ways. Yet little is known about how variation in diverse cultural ecologies influences how people integrate natural and supernatural explanations. Here, we examine explanatory coexistence in three existentially arousing domains of human thought: illness, death, and human origins using qualitative data from interviews conducted in Tanna, Vanuatu. Vanuatu, a Melanesian archipelago, provides a cultural context ideal for examining variation in explanatory coexistence due (...) to the lack of industrialization and the relatively recent introduction of Christianity and Western education. We argue for the integration of interdisciplinary methodologies from cognitive science and anthropology to inform research on explanatory coexistence. (shrink)

Religion has been intensely studied in the last years inside an evolutionary frame, trying to discern to what extent it contributes to fitness or becomes an adaptive entity in its own. A similar heuristic can be tried regarding the opposite tendency: unbelief and atheism, since these cultural phenomena could help to better adapt to some social settings or become an adaptive socio-cultural niche on its own. The present paper examines some scenarios in which that question makes sense: the tradition of (...) sociology of religion, with its different strands, including recent studies on ‘non-religious’; the cognitive; and the philosophical-theological reflection. The proposed venues show to what extent the evolutionary model might reveal neglected aspects in the study of unbelief, and at the same time its limits or the open questions that such application raise.

We develop a cultural evolutionary theory of the origins of prosocial religions and apply it to resolve two puzzles in human psychology and cultural history: (1) the rise of large-scale cooperation among strangers and, simultaneously, (2) the spread of prosocial religions in the last 10–12 millennia. We argue that these two developments were importantly linked and mutually energizing. We explain how a package of culturally evolved religious beliefs and practices characterized by increasingly potent, moralizing, supernatural agents, credible displays of faith, (...) and other psychologically active elements conducive to social solidarity promoted high fertility rates and large-scale cooperation with co-religionists, often contributing to success in intergroup competition and conflict. In turn, prosocial religious beliefs and practices spread and aggregated as these successful groups expanded, or were copied by less successful groups. This synthesis is grounded in the idea that although religious beliefs and practices originally arose as nonadaptive by-products of innate cognitive functions, particular cultural variants were then selected for their prosocial effects in a long-term, cultural evolutionary process. This framework (1) reconciles key aspects of the adaptationist and by-product approaches to the origins of religion, (2) explains a variety of empirical observations that have not received adequate attention, and (3) generates novel predictions. Converging lines of evidence drawn from diverse disciplines provide empirical support while at the same time encouraging new research directions and opening up new questions for exploration and debate.

The Cognitive Science of Religion commonly advances the view that religious beliefs emerge naturally via specific cognitive biases without cultural influence. From this perspective comes the claim that self-proclaimed atheists harbour traces of supernatural thinking. By exploring the potential influence of the cultural learning mechanism Credibility Enhancing Displays, which affirms beliefs, current disparities between studies involved in priming the implicit theism of atheists, might be reconciled. Eighty-eight university students were randomly assigned to either a religious or control prime condition. A (...) dictator game was completed to obtain an indication of pro-social behaviour. Lifetime theists reported significantly higher religiouscreds exposure levels than lifetime atheists, though not convert atheists. Conversely, lifetime atheists reported significantly lowercreds exposure scores than convert atheists. Convert atheists in the prime condition were significantly more pro-social than lifetime atheists. Additionally, higher scores on thecreds exposure measure equated to higherpsbin the religious condition than the control condition. The results are consistent with the view that supernatural belief formation is an interactive process between both context and content biases, and that in order to accurately test for implicit theism, past personal differences in exposure to religiouscreds should be considered.

We hypothesised that belief in conspiracy theories would be predicted by the general tendency to attribute agency and intentionality where it is unlikely to exist. We further hypothesised that this tendency would explain the relationship between education level and belief in conspiracy theories, where lower levels of education have been found to be associated with higher conspiracy belief. In Study 1 participants were more likely to agree with a range of conspiracy theories if they also tended to attribute intentionality and (...) agency to inanimate objects. As predicted, this relationship accounted for the link between education level and belief in conspiracy theories. We replicated this finding in Study 2, whilst taking into account beliefs in paranormal phenomena. These results suggest that education may undermine the reasoning processes and assumptions that are reflected in conspiracy belief. (shrink)

[OPEN ACCESS TARGET ARTICLE WITH COMMENTARIES AND RESPONSE] We develop a new model of how human agency-detection capacities and other socio-cognitive biases are involved in forming religious beliefs. Crucially, we distinguish general religious beliefs (such as *God exists*) from personal religious beliefs that directly refer to the agent holding the belief or to her peripersonal time and space (such as *God appeared to _me_ last night*). On our model, people acquire general religious beliefs mostly from their surrounding culture; however, people (...) use agency-intuitions and other low-level experiences to form personal religious beliefs. We call our model the Interactive Religious Experience Model (IREM). IREM inverts received versions of Hyperactive Agency-Detection Device Theory (HADD Theory): instead of saying that agency-intuitions are major causes of religious belief in general, IREM says that general belief in supernatural agents causes people to seek situations that trigger agency-intuitions and other experiences, since these enable one to form personal beliefs about those agents. In addition to developing this model, we (1) present empirical and conceptual difficulties with received versions of HADD Theory, (2) explain how IREM incorporates philosophical work on indexical belief, (3) relate IREM to existing anthropological and psychological research, and (4) propose future empirical research programs based on IREM.
