Religion is present in virtually all known human societies. In spite of obvious cultural variation, many traits of religious thought and behavior are remarkably consistent across time and space. People around the world interact with superhuman agents—that is, gods, spirits, and ancestors—that are similar to humans in many respects but also display some superhuman abilities, such as invisibility or knowledge of people's thoughts and feelings. In small and large societies around the globe, rituals are performed that are connected to shared themes and occasions, such as communication with the gods, sacrifices, initiation of young people into the community, or deposing dead bodies. Why is religion so widespread (indeed, virtually omnipresent) in human societies and why does it assume fairly consistent forms? Cognitive studies of religion (often referred to as the cognitive science of religion) examine cross-culturally consistent patterns of religious thought and behavior. Although cognitive scientists study the human mind in general, scholars pursuing cognitive studies of religion ask how the structure of the mind shapes religion. Like cognitive science itself, the cognitive approach to religion is interdisciplinary in the sense that it uses methods and theories from a range of academic fields. Neuroimaging technology is used to observe changes in the functioning of the brain while people engage in religious meditation or bible reading. Experimental psychology is used to test hypotheses about religious concepts and the influence of religion on ethical behavior, among others. The emerging field of experimental ethnography studies people engaged in religious practices both in the field and in the laboratory. Evolutionary theory is used to make sense of the roots of religion in the distant past of humankind. Computer models help to test ideas and analyze data about religious beliefs and communities. The philosophy of mind inquires about the nature of religious experience, as well as the relationship of the mind to the brain, the body, and the environment. This chapter reviews the intersection between the study of religion, human cognition, and culture, tying together these many approaches to understanding religious cognition and culture.
