I missed the point where evidence that hypnosis works has been established. That is, I know it works from personal experience, but a lot of people have been claiming that it's hogwash for a long time, and unambiguous empirical study of the matter has proven rather difficult. Thus it's interesting that this study takes for granted that the distinction between hypnotic and non-hypnotic state is well-defined. If that really has been established, it's news.

The exact nature of a hypnotic state is widely debated. But hypnosis being hogwash and hypnosis working for some are not mutually exclusive hypotheses. The test shows that there were differences of some kind between hypnotized and non hypnotized patients. Maybe it is hogwash, and only works because they think it will, but that doesn't change the fact that they are in a measurably different state.

  If they're in a repeatably measurably different state, that's the very definition of not being hogwash. The key word is "measurably". The interesting thing is that if MRI techniques have established a repeatably measurable distinction between people who are in a trance and people who are not in a trance, that's a far bigger deal than the specific finding reported here (which appears to presuppose that).

That's why reading this blog post is inferior to actually reading the paper, although it's better than most of what passes for science journalism these days in that they at least bothered to give a proper link to the paper's abstract. In the third paragraph of the paper's introduction, the authors cite six prior fMRI studies of hypnotic vs. non-hypnotic states, the first of them dating back as far as 1997. If those six papers employed careful methodology and measured a statistically significant result, then I'd say it's pretty well established. I don't particularly care enough about it to go look up all of those other papers, but I suspect the phenomenon's neurological basis is probably well established and the detractors calling it hogwash are probably not neuroscientists.

  Thanks! You're absolutely right about reading the paper. I should have looked at it before posting; casualty of the constant battle to minimize online distractions. I appreciate your digging that information up.
