Well, all psychologists who use hypnosis are basically 'average people'.
Hypnosis can be dangerous, but so can most things.
Hypnosis can also be a very useful tool for changing behaviour. From as simple as quitting smoking to as major as dealing with and overcoming things
like social anxiety.
Also, there are ways to hypnotize yourself for the same, behaviour altering reasons.
As to why some people can be and others not - i don't know anything about this... if anyone else does, i'm curious.
I would venture that it may have to do with expectation/skepticism, but i believe skeptics can, and have been, hypnotized... so.. i don't know.
