Maybe I can seem certain of my opinions because my opinions are informed. I never said anyone was "faking."
I would settle for the old double blind study.
No need to apologize. I knew it would be something or another.
Why can't they do double blind testing against non-hypnotized volunteers and see how it turns out?
There is no shame on you the gizmo may not work this way.
Well, you do insist that hypnosis does not entail any sort of "altered state" of consciousness for some reason. For someone who has been helped by hypnosis and who has experienced that state, it would sound just a bit like an inept accusation that they must be "faking" the trance state. But, fair enough, if you don't believe they are faking it, just what do you think is going on? Voluntary compliance with instructions?
I don't understand how my post came through to you as any sort of "apology" or how it calls for you to absolve me of "shame". That my coherent explanation of a vagal tone monitor came across to you as a "gizmo" is telling. That's quite a bizarre interpretation of a post that merely states the facts. I'm attempting to deal in good faith with your objections, and I assure you that I have no ax to grind either with the so-called "non-believers" nor with practitioners in the hypnosis profession. I did hypnosis as a college student and later designed and built various devices (VTM, EEG, GSR) that had relevance for hypnosis professionals.
You are welcome to your "informed opinions". I just ask again that you support them with some sort of argument or evidence in the form of publications from sources other than people who are guessing about the nature of hypnosis. I have no idea what informs this opinion. Are you a medical professional? It sounds like you have simply dug in your heels in order to reinforce a pre-existing idea about the subject with no real basis for your belief.
As for the experimental data, there is no lack of evidence for the positive benefits of hypnosis. The nature of the state has been documented in many ways, including the use of some of the same instruments in polygraphy. I would imagine that by now even FMRI researchers have found evidence for the hypnotic state. One
meta analysis I found looked at success rates of hypnotherapy. I'd be inclined to say "who cares whether hypnosis is an altered state or not?" when confronted with data like these.
The authors considered a total of 444 studies on hypnotherapy published prior to 2002. By selecting the best quality and most suitable research designs for meta-analysis they narrowed their focus down to 57 controlled trials. These showed that on average hypnotherapy achieved at least 64% success compared to 37% improvement among untreated control groups. (Based on the figures produced by binomial effect size display or BESD.)
According to the authors this was an intentional underestimation. Their professed aim was to discover whether, even under the most skeptical weighing of the evidence, hypnotherapy was still proven effective. They showed conclusively that it was.
Opinion of the British Medical Association:
For the past hundred years there has been an abundance of evidence that psychological and physiological changes could be produced by hypnotism which were worth study on their own account, and also that such changes might be of great service in the treatment of patients.
American Medical Association report:
"That the use of hypnosis has a recognized place in the medical armamentarium and is a useful technique in the treatment of certain illnesses when employed by qualified medical and dental personnel."
Again, the AMA council approved this report rendering hypnotherapy an orthodox treatment.
The Reference Committee on Hygiene, Public Health, and Industrial Health approved the report and commended the Council on Mental Health for its work. The House of Delegates adopted the Reference Committee report...
I am satisfied that hypnosis amounts to significantly more than someone sitting around offering "suggestions" for a patient suffering excruciating pain that he just forget about it.
Here is a rather good article from the University of Maryland Medical Center that outlines the use of hypnotherapy with an extensive bibliography for those interested in more information.

Hypnotherapy regained popularity in the mid-1900s due to Milton H. Erickson (1901 - 1980), a successful psychiatrist who used hypnosis in his practice. In 1958, both the American Medical Association and the American Psychological Association recognized hypnotherapy as a valid medical procedure. Since 1995, the National Institutes of Health (NIH) has recommended hypnotherapy as a treatment for chronic pain.
Other conditions for which hypnotherapy is frequently used include anxiety and addiction.
