Hypnotism

[needimprovement]

If so, how? If not, why not?

 

I quote from the Wikipedia article on Hypnosis:

 

Hypnosis is a mental state (according to "state theory") or imaginative role-enactment (according to "non-state theory").[1][2][3][4] It is usually induced by a procedure known as a hypnotic induction, which is commonly composed of a long series of preliminary instructions and suggestions.[5] Hypnotic suggestions may be delivered by a hypnotist in the presence of the subject, or may be self-administered ("self-suggestion" or "autosuggestion"). The use of hypnotism for therapeutic purposes is referred to as "hypnotherapy".

Well, it does seem to do something. However it won't allow you to mind-control people like it does in the movies.

Depend on what you mean by "work".
