Being the Society is anti-hypnosis, I know very little about it. But from what I've observed it often involves willing participants focusing their concentration, usually involving repetition, until the subject is in a state where suggestions can be implanted in their mind.
BITE can involve hypnosis, but in many instances it may not. However the BITE system even apart from hypnosis, seems to accomplish the very same goal. A participant is willing, to one degree or another, in a focused indoctrination process, and by force of repetition and loaded language, suggestions are implanted that are deep as if not deeper than what hypnosis could produce. Perhaps it has to do with the shaping of neural pathways over a long period of time.
Under the Society's direction, a study may last six months to a year. Meanwhile they may start attending meetings and assemblies. And the neverending reading treadmill begins as well. Slowly suggestions are cemented into place and are hard to shake. Thus, the important to attend as many meetings as possible.
Years back, I was sitting in my seat in a relaxed manner before the meeting, and the CO was chatting with me. Suddenly, the chairman got up onto the stage to start the meeting, and my body, of its own accord, straightened in the chair, shifting into meeting mode. I think it was due to decades of meeting attendance from infancy. The brother got up on stage and my body automatically started to prepare without conscious thought.
If these suggestions are cemented into place, then no wonder they are hard to shake. No wonder friends and relatives still in will get this strange look in their eyes and get defensive when doubts about the "Faithful Slave" are raised. No wonder there are strange leaps of desperate 'logic'. We might be dealing with something stronger than hypnosis.
