The obvious one is how to spot the susceptible in a crowd, and how you know this . How does resistance appear? Is there any validity to the brute force approach depicted in media? What are the hard limits? How do existing psychological conditions come into it? How do people react before and after? How many have punched you?
Ok let me see
How to spot the susceptible in a crowd
-The hypnotist isn't doing nothing when he is up there talking about hypnosis or himself. He is actually doing an induction and is trying to spot people in the crowd who are falling for it. Since the level of sensitivity is 5-10% it means that in a crowd of 100 he has 5 to 10 volunteers. Plus he can plant more himself (In fact it is common for a hypnotist to specifically get sensitive subjects to sit in the crowd... OR to fake it). The second trick is that quite a few people will fake being hypnotized when in a crowd of hypnotized (or seemingly so) people.
How does resistance appear?
-Well resistance to hypnosis itself is usually just the inability to handle the type of induction being performed or just inexperience or fear with the hypnosis structure itself. In terms of the subject being afraid that is one of the easier resistances to handle because hypnosis doesn't have to be dictated to people.
-It is actually quite complicated.
Is there any validity to the brute force approach depicted in media?
-Frankly? No. While I will say that hypnosis is a lot more dangerous then stage hypnotists will have you believe (for example in terms of "What can hypnosis make me do?" the answer is, anything alcohol could make you do), the idea of someone just forcing you down doing an induction and hypnotizing you is completely fiction, even if you were sensitive.
What are the hard limits?
-The Alcohol test: If you would do it while really drunk, you would do it under hypnosis. That is "The" hard limit.
How do existing psychological conditions come into it?
-For some conditions hypnosis is completely unsuggested. Scizos for example should not be hypnotized period because it can aggravate their condition. For others it just means that the phrasing needs to be different and that certain subjects should be avoided.
How do people react before and after?
-Before: Often fearful to approach and sometimes eager. For those most afraid I do subject lead hypnosis (basically I dictate nothing, I consistently ask the subject)
-After: They usually had a great time, some though have a condition I like to call "Hypnosis Amnesia" which is fairly common where they find it difficult to impossible to remember the session.
How many have punched you?
-Stage hypnotists job is to wow the crowd and thus they are the most invasive and abusive hypnotists you will see consistently. My job is to make sure the subject (the person being hypnotized) is having a great time and thus being invasive and abusive is the best way not to have that happen. In fact I tend to ask people what they want.
-That and I do the vast majority of it online so being punched is kind of hard through a computer screen or text... Though even then none of them would have punched me.
