The signaling theory of religion has many claimed virtues, but these are not necessarily all realizable at the same time. Modeling choices involve trade-offs, and the available options here have not traditionally been well understood. This paper offers an overview of signaling theory relevant to the signaling theory of religion, arguing for a narrow, “core” reading of it. I outline a broad taxonomy of the choices on offer for signaling models, and examples of how previous and potential approaches to modeling (...) religious signaling meet or fail to meet the initial promise of the theory. A pluralist approach to religious signaling seems possible, but this would require a high level of detail and specificity with respect to both formal models and target systems. (shrink)

Sacred value attitudes involve a distinctive profile of norm psychology: an absolutist prohibition on transgressing the value, combined with outrage at even hypothetical transgressions. This article considers three mechanisms by which such attitudes may be adaptive, and relates them to central theories regarding the evolution of religion. The first, “deterrence” mechanism functions to dissuade coercive expropriation of valuable resources. This mechanism explains the existence of sacred value attitudes prior to the development of religion and also explains analogues of sacred value (...) in non-human species. The two remaining mechanisms, “assurance” and “coalitional,” are more likely to have been involved in the cultural evolution of specifically religious behavior. In the assurance mechanism, sacred value attitudes increase the cost of ideological commitments, making them more reliable as signals of a cooperative disposition. In the coalitional mechanism, sacred value attitudes make it dangerous for third parties to dissent from a social norm, and thus discourage competitor ideologies. While both these mechanisms are compatible with major accounts of the evolution of religion, different theories suggest a greater or lesser emphasis on one mechanism or the other. (shrink)
