During the MK Ultra years, the CIA interviewed a hypnotist who told them they could use hypnotism on the masses if they could find a way to keep people entertained.

“Q: Do you have any ideas that hypnotism could be used as a weapon?

A: Yes, I have thought about this often. It could certainly be used in obtaining information from recalcitrant people, particularly with drugs: Furthermore, it can be used as a morale factor and in addition, it could be used as a recruiting source for special types of work. I will explain the last two.

You have large D.P. camps in Europe and Asia. You have to entertain these people. A good professional hypnotist is a good entertainer. Using mass hypnotic methods, he could drive home thoughts that would be of great benefit to our aide.

Individuals that he gained control of through hypnotic influence could be converted to strong supporters of our viewpoint through suggestion. The opposite of this, of course, would hold true.

Furthermore, along these lines, a good hypnotist running hypnotic shows for entertainment would pick up a great many subjects; some of whom might be exceptionally good subjects for us. These subjects could easily be tabbed and put to our use.”
