What would move my needle is reproducible results, i.e. science.
For example, have a shaman go into a room and describe the spirit he sees. Then have another shaman go into the room, and see if his description matches.
Or, write about how many schizophrenic people this shaman has actually cured. Interview the patients, do a profile of their lives before and after, and explain the process that was used.
While this article is interesting from a cultural perspective, I still don't see how it is OT for HN.
a psychiatrist goes into a room with a patient, has a brief conversation with him and then comes out and says "I see schizophrenia." a second psychiatrist goes in and has a conversation with the same patient and says "yes I concur, I see schizophrenia."
