I do a comedy juggling show, and I have volunteers from the audience do all sorts of very strange, silly, and sometimes apparently dangerous things on stage. All I do is ask for volunteers and tell them what to do. Sorry "induction" is just a bit of play acting.
In over 20 years (thousands of shows), I'll be there've been a total of maybe a dozen people who refused to do what I ask them. There have been thousands of volunteers who did the things I asked them to because there is an expectation based on the situation 1) that I won't hurt them and 2) that it's all in fun.
Granted, the compliance I get in my act doesn't prove that you're not doing what you say you are, but if you're actually "inducing" people into some sort of state that they need to "come out of," you're doing it the hard way. I think you're just screening for people who are willing to play along with their roles in this sort of situation, very much the way improv troupes do.
Sorry, I was trying to answer Zas' questions. Please realize that I'm using the words "inducing" and "trance" simply because there's no real scientific word for it.
Of course what I'm doing is the same as a comedy imporv troup (which I've been a part of also), or what you do (I can't juggle...

), but that's my point: all of it is a mixture of trust, desire, suggestablity, concentration and relaxation. Nothing magical, nothing woo. Just something we all naturally do.
Each different kind of performer uses different "inductions", or maybe a better word in this case would be "pratter", to achieve, for lack of a better word, that "state" they want their participants in.
And of course I'm weeding out the people. I do that right on stage in front of everyone. I don't hide it at all. I'm looking for people who are more suggestable than the others. (Please note: suggestable does not mean gullible. It can, but not always).
I've said it before in this thread and I'll reinterate it here:
Go to a good movie. Sit in your seat. Watch the film. If the movie, if the visuals, the dialogue, the charactors, the actors, etc, "touch" you in any way, you will be drawn into the movie. You'll forget that you are merely in a seat. You won't notice the people coming back from the consession stand.
Your heart beats faster during the exciting scenes, you might cry with the sad scenes, you might cheer at the victorious scenes.
Then at the end of the film, you walk out still feeling the experience of what you saw. Did you actually go through it? Physically, no. However, let me ask you this: How did you feel when the Death Star blew up?
That's what I do. Only I don't use visuals, I use words. I'm basically a poet. Whether performing onstage or individually, I use someone's desire, focus and suggestablity, to plant a feeling in the mind. Some people really get into it and "experience" it. Some people do to a lesser extent. But it's a real thing we all do to ourselves and each other every day.
I claim no supernatural powers. I claim no psychic ablity. In fact, the first thing I do in every show is use the movie example to explain hypnosis. I am very upfront with the audience. And yet, it still works.
And it works because a) it's something we do everyday to ourselves and b)there are many ways to get people into that "state": Confusion, distraction, the right words, a reward system, negative reinforcement and many many other psychological exercises I use to get someone in that "state". Nothing fancy, nothing supernatural.
Now I don't know how it can be measured, I don't know if it can. This is a subjective thing. Different people are going to react differently in different situtations: some people reach that "state" by adding numbers, some by reading, some listening to a person drone on and on (like me right now.

)
And in the case of therapy, I've said it before, too: quitting smoking, losing weight, etc, via hypnosis only works because the subject really is ready to do so. There's a reward system built up, if the "hypnosis award" is greater than the "habit reward" and the person is really ready to change, it will work.
Let me give you an example: I lost 130 pounds between Nov 2003 to May 2005. I used Weight Watchers and exercise. However, whenever I was tempted to break the diet I would hold out my hands palm up and say to myself "Do I want to eat this?" and move my right hand up and down slightly, "or do I want to meet women?" and move my left hand slightly. I'd then look at the hands for a bit and toss my right hand over my shoulder and say "meet women". I still do it to this day.
Is that hypnosis? In a way, yes. It is a ritutal that enforces my desire to eat smartly, makes me focus, allows me to exploit my own suggestablity and reinforces my eventual reward. Now if the eating was more of a reward, the ritual would be useless. But it works on me partly because I was ready to lose weight. I had made that final choice. If I wasn't really ready, if I was half-*ssed about it, it wouldn't have made all that much of a difference.
The point is: I'm doing nothing different than what a movie maker does, or a book writer, an intimidating boss, or even what you do to yourself to get motivated. I just use different psychological techinques and dress it differently.
.....and sorry for the long post, I hope that helps explain my position.
