There is considerable evidence that beliefs in supernatural punishment decrease self-interested behavior and increase cooperation amongst group members. To date, research has largely focused on beliefs concerning omniscient moralistic gods in large-scale societies. While there is an abundance of ethnographic accounts documenting fear of supernatural punishment, there is a dearth of systematic cross-cultural comparative quantitative evidence as to whether belief in supernatural agents with limited powers in small-scale societies also exert these effects. Here, we examine information extracted from the Human (...) Relations Area Files on cultural discourse about the recently deceased, local ancestor spirits, and mortuary practices across 57 representative cultures. We find evidence that in traditional small-scale societies ancestor spirits are commonly believed to be capable of inflicting harm, with many attendant practices aimed at mitigating this danger. However, such beliefs do not appear to promote cooperation, as ancestor spirits seem to be concerned with interactions between themselves and the living, and to prioritize their own welfare. Many attendant practices are inconsistent even with bipartite cooperation with ancestors that could be viewed as a model for other relationships. The broader implications of this research for the cultural evolution of religion are discussed. (shrink)

Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is (...) affected by feelings of randomness. In a between-subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem-solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed. (shrink)

Although I certainly have differences with some of my commentators, I am grateful for the time, effort, and attention that each has devoted to my book, Why Religion Is Natural and Science Is Not. They have helpfully pointed out features of my positions that need clarification and elaboration. I am also grateful to the editor of Zygon, Willem Drees, for this opportunity to undertake that task here.

Comparing mortuary rituals across 57 representative cultures extracted from the Human Relations Area Files, this paper demonstrates that kin of the deceased engage in behaviours to prepare the deceased for disposal that entail close and often prolonged contact with the contaminating corpse. At first glance, such practices are costly and lack obvious payoffs. Building on prior functionalist approaches, we present an explanation of corpse treatment that takes account of the unique adaptive challenges entailed by the death of a loved one. (...) We propose that intimate contact with the corpse provides the bereaved with extensive veridical cues of death, thereby facilitating acceleration of a grieving process that serves to recategorize the deceased as no longer a relationship partner, opening the door to relationship replacement and a return to social functioning. The benefits of exposure to such cues are tempered by the costs of exposure to cues of disease risk, a balance that in part explains the relative rarity of highly invasive mortuary practices that exacerbate the latter factor. We conclude by discussing implications of our model for contemporary mortuary practices in the developed world. (shrink)

The present studies were motivated by the hypothesis that attenuated access to internal states in obsessive-compulsive (OC) individuals, which leads to extensive reliance on external proxies, may manifest in a maximizing decision making style, i.e., to seeking the best option through an exhaustive search of all existing alternatives. Following previous research, we aimed to explore the possible relationships between OC tendencies, seeking proxies for internal states, indecisiveness and maximization. In Study 1, we measured levels of OC tendencies, seeking proxies for (...) internal states, indecisiveness, maximization, depression and anxiety in an online Hebrew speaking sample (N = 201). In Study 2, we administrated the same questionnaires to an online English speaking sample (N = 240) and in addition, examined participants’ decision making strategies in a hypothetical situation. The participants in both studies were unscreened adults. Correlational and linear regressions analyses indicated that OC tendencies are related to maximization, even when levels of indecisiveness, depression and anxiety are controlled for. Moreover, the findings suggested that reliance on external proxies may partially account for the aforementioned association. Possible implications and future directions are discussed. (shrink)
