I think that "Combatting Cult Mind Control" by Steven hassan touches on a hypnotic style indoctrination that uses long hours of boring non sense to get you into the state of mind that allows you to accept certain beliefs without questioning them.
Notice how all the new info comes out toward the end of a multi day District Convention or Circuit assembly? Also were we not told ( I cannot not remember) to not tell others that have not attended their own DC and CA anout any "new light"?
If so, it goes hand in hand with getting the mind prepped prior for non critical thinking just before releasing the info to the masses.
Also releasing the new info at this point at a DC or a CA, while inthe midst of SO MANY friends all clapping in agreement makes it easier to swallow as compared to hearing about any new light while alone without all the pre mind numbing days of previous talks.
They have had quite awhile to perfect these processes.
