Abstract

Individual-specific predispositions may precede the cultural evolution of shamanism and may be linked to it via principles of predictive coding. We have used these principles to identify commonalities between clinical and shaman-like non-clinical voice-hearers. The author may find this approach helpful in relating the experiences of shamans to those of their clients.
