Are participants in stage hypnosis paid stooges?
I ask this after watching a recent Derren Brown (UK stage magician and hypnotist) TV program in which he sets out to discredit faith healers, yet trains his accomplices in hypnotism, apparently without irony. I've always assumed that stage hypnotism was an obvious fake (specifically that participants pretend and lie), but am perplexed to find that the reality of the phenomenon is still controversial, at least if Google results are representative of scientific opinion.
There ought to be falsifiable predictions arising from the reality of hypnotism as a brain phenomenon. For example, can the response be elicited in people from cultures not exposed to Western TV?
