Of Boyer's books,
Religion Explained: The Evolutionary Origins of Religious Thought is the best known. Boyer used
cognitive anthropology, to provide a new understanding of religion. Religion for Boyer consists of cultural representations, that is, ideas that appear in roughly similar forms in the minds of different individuals in a group. To explain how religion emerges and is transmitted, we must explain how these ideas are acquired, stored and transmitted better than other possible ideas. Findings from cognitive and developmental psychology suggest that some combinations of ideas are particularly easy to acquire and remember. Among these, we find many standard themes of supernatural and religious imagination, such as the notion of an agent with counter-intuitive physics and standard psychology, e.g. ghosts and gods that are not material but have the same mental capacities as humans. According to Boyer, there are only a few such combinations of intuitive and counter-intuitive material that are optimal for acquisition and memory - and these happen to be the most frequent ones in the world's religions. In this cognitive paradigm belief in
supernatural agents is natural and part of human cognition. However, religion is not "special". That is, there are no specific mental systems that create religious ideas. Rather, these ideas are an expected by-product of mental systems that evolved for other reasons, not for religion. For instance, we easily entertain the notion of a "god" or "ghost" because of our intuitive psychology, what psychologists sometimes call "
Theory of Mind".
Justin L. Barrett has argued that Boyer’s book,
The Naturalness of Religious Ideas: A Cognitive Theory of Religion is an attempt to reform traditional models and allow understanding religion in terms of cognitive science. Boyer dismantles many traditional assumptions of cultural studies. However, Barrett claims, Boyer lacks clarity – mostly due to the shift in anthropological to psychological jargon. ==
