In this paper we o¤er a new theory of religion. Our theory relies on the assumption that individuals in society have di¤erent beliefs about the statistical relation between their actions in a strategic social interaction (speci…cally, a Prisoner’s Dilemma) and uncertain events that a¤ect their utility. This heterogeneity of beliefs allows for the endogenous emergence of religious institutions; ...

Within disciplines of religious studies, discussions of religious experience tend to revolve around the most rare and extraordinary cases, while neglecting much more common varieties of “ordinary religious experience”—that is, experiences of regular practitioners in the midst of normal religious activities such as worship or prayer. This comment will, first, call attention to this essential asp...

Functional neuroimaging techniques such as single-positron emission computed tomography (SPECT) and positron emission tomography (PET) offer considerable scope for investigating disturbances of brain activity in psychiatric disorders. However, the heterogeneous nature of disorders such as schizophrenia limits the value of studies that group patients under this global label. Some have addressed ...

When groups compete for members, the resulting dynamics of human social activity may be understandable with simple mathematical models. Here, we apply techniques from dynamical systems and perturbation theory to analyze a theoretical framework for the growth and decline of competing social groups. We present a new treatment of the competition for adherents between religious and irreligious segm...

Trust is a critical aspect of social interaction. One might predict that individuals trust religious out-groups less than religious in-groups, and that costly signals performed by members of religious in-groups increase trust while costly signals performed by members of religious out-groups decrease trust. We examined how Christian participants perceived the trustworthiness of Muslim and Christ...

The paper analyzes the relation between religious beliefs, religious participation and social cooperation. In particular, we focus on religions that instill beliefs about the connection between rewards and punishments and social behaviour. We show how religious organizations arise endogenously, analyze their e¤ect on social interactions in society and identify a "spiritual" as well as a "materi...

In the last decade, a number of studies have shown the success of spiritual medicine. These studies come from a wide number of fields and deal with many aspects of religious and spiritual practice. A recent study by Koenig et al (1999), looking at a population of nearly four thousand 65 year-old people over a six-year period, was able to show that those who go to church at least once a week are...

Applying evolutionary analyses to the study of religion is fraught with complications and potential misunderstandings. Most notably, the evolutionary sciences do not offer one clear procedure to study religion or any human activity. Here we describe the behavioral ecological approach to religion. We explain the theoretical motivations behind behavioral ecological research and discuss the method...

Context. Solar activity poses substantial risk for astronauts of the International Space Station (ISS) both on board and during extravehicular activity. An accurate assessment of the charged radiation flux in space habitats is necessary to determine the risk and the specific type of radiation exposure of ISS crew members, and to develop ways to protect future crews for planetary missions, even ...

Past research argues that religious commitments shape individuals’ prosocial sentiments, including their generosity and solidarity. But what drives the prosociality of less religious people? Three studies tested the hypothesis that, with fewer religious expectations of prosociality, less religious individuals’ levels of compassion will play a larger role in their prosocial tendencies. In Study ...
