It has nothing to do with IQ. It has to do with breaking down your ability to maintain your sanity in order to survive. They break your sense of reality in every conceivable way: confuse your sense of time, force you to abandon logical thinking, make you question and doubt your own feelings, make you expect and accept the opposite of what you normally would in a given situation, etc. Just take away your connection to the rest of the world for a few days and you will soon start to attach yourself to those who keep you. You will learn quickly that they control everything in your environment. When they start suddenly playing games with you, you become confused and scared. You begin to forget about everything but your current situation and how to get through it. You begin to cooperate. By cooperating, you are forced to confound your natural instincts and begin reinterpreting reality through their constructed substitute reality. You are ready to become a different person, one that they mould. The method described by Polly is preliminary to the actual programming. @Trish2020
