The commentators endorse the conceptual and ethnographic synthesis presented in the target article, suggest extensions and elaborations of the theory, and generalize its logic to explain apparently similar specializations. They also demand clarity about psychological mechanisms, argue against conclusions drawn about empirical phenomena, and propose alternative accounts for why shamanism develops. Here, I respond.

Shamans, including medicine men, mediums, and the prophets of religious movements, recur across human societies. Shamanism also existed among nearly all documented hunter-gatherers, likely characterized the religious lives of many ancestral humans, and is often proposed by anthropologists to be the “first profession,” representing the first institutionalized division of labor beyond age and sex. In this article, I propose a cultural evolutionary theory to explain why shamanism consistently develops and, in particular, (1) why shamanic traditions exhibit recurrent features around the (...) world; (2) why shamanism professionalizes early, often in the absence of other specialization; and (3) how shifting social conditions affect the form or existence of shamanism. According to this theory, shamanism is a set of traditions developed through cultural evolution that adapts to people's intuitions to convince observers that a practitioner can influence otherwise unpredictable, significant events. The shaman does this by ostensibly transforming during initiation and trance, violating folk intuitions of humanness to assure group members that he or she can interact with the invisible forces that control uncertain outcomes. Entry requirements for becoming a shaman persist because the practitioner's credibility depends on his or her “transforming.” This contrasts with dealing with problems that have identifiable solutions (such as building a canoe), in which credibility hinges on showing results and outsiders can invade the jurisdiction by producing the outcome. Shamanism is an ancient human institution that recurs because of the capacity of cultural evolution to produce practices adapted to innate psychological tendencies. (shrink)

The history of psychology in Japan from the late 19th century until the first half of the 20th century did not follow a smooth course. After the first psychological laboratory was established at Tokyo Imperial University in 1903, psychology in Japan developed as individual specialties until the Japanese Psychological Association was established in 1927. During that time, Tomokichi Fukurai, an associate professor at Tokyo Imperial University, became involved with psychical research until he was forced out in 1913. The Fukurai affair, (...) as it is sometimes called, was not documented in textbooks on the history of Japanese psychology prior to the late 1990s. Among earlier generations of Japanese psychologists, it has even been taboo for discussion. Today, the affair and its after-effects are considered to have been a major deterrent in the advancement of clinical psychology in Japan during the first half of the 20th century. (shrink)

This article reviews the origins of the concept of the shaman and the principal sources of controversy regarding the existence and nature of shamanism. Confusion regarding the nature of shamanism is clarified with a review of research providing empirical support for a cross-cultural concept of shamans that distinguishes them from related shamanistic healers. The common shamanistic universals involving altered states of consciousness are examined from psychobiological perspectives to illustrate shamanism’s relationships to human nature. Common biological aspects of altered states of (...) consciousness help explain the origins of shamanism while social influences on this aspect of human nature help to explain the diverse manifestations of shamanistic phenomena involving an elicitation of endogenous healing responses.
