Religious persons acquire religious ideas and practices through social exposure. The child of a Zen Buddhist will not become an evangelical Christian or a Zulu warrior without the relevant cultural experience. While mere exposure does not cause a particular religious outlook (a person may have been raised a Roman Catholic but leave the church), nevertheless some exposure seems required – this person will never invent Roman Catholicism out of thin air. Boyer says cognitive science can help us to understand the psychological mechanisms that account for these manifest correlations and in so doing enable us to better understand the nature of religious belief and practice.
