In this article published in Harper's magazine back in 1996, journalist David Foster Wallace described his experience with hypnotist Nigel Ellery (see the last section of the article, titled "THE HEADLINE ENTERTAINMENT"). Mr Ellery was providing part of the entertainment on the cruise ship that David was on.
As to hypnotism, David writes that:
First off, we learn that not everyone is susceptible to serious hypnosis: Nigel Ellery puts the Celebrity Show Lounge's whole 300-plus crowd through some simple in-your-seat tests to determine who is suggestibly "gifted" enough to "participate" in the "fun" to come.
In the footnote to that paragraph just quoted, David writes that:
I, who know from hard experience that I am hypnotizable, think about sports statistics and deliberately flunk a couple of the tests to avoid getting up there.
The question I wanted to ask is, are there any studies looking into why some people would be more susceptible to hypnotism?
What I am particularly interested in is whether this has something to do with a habitual activation or inactivation of parts of the brain, or perhaps the levels of some neuromodulators?
