I dont hold any doctorate degree in human psychology but if you look at the JWS from a layman's perspective of whats going on inside the head of your typical JWS it isn't that are hard to understand.
If you haven't noticed the JWS have the propensity to reiterate word for word what the WTS teaches and fills the heads of people who are strongly attached to the JWS religion.
In short the WTS tells people what to think and what to say about various topics, theology based or otherwise. How that comes about is the wholehearted acceptance that what comes to the readers off the pages of the WTS's literature, has come from god's chosen earthly mediators the GB men.
This information is essentially deemed life saving information or beneficial to the lives who would accept these teachings and social guidance.
Unfortunately the reality is these teachings have been drawn out from men who were not well educated from today's knowledge base.
Most have actually come from reading the bible and intentionally set about to emulating the social activity and expressions of the ancient Hebrew civilization, a civilization that existed 3000 years ago.
It seems once it has been accepted that certain self proclaiming men (GB leaders) have important designated spiritual information, that it will be accepted without question or critical evaluation, it will be embraced with the upmost respect.
The WTS has strategically mentally indoctrinating people with its own self supporting information to lure people into the organization where they can be exploited and manipulated in the WTS's literature proliferation agenda.
Spiritual information or "Food at the Proper Time" was actually lies and corruption propagated with fear and ignorance. The realization of the fact has caused many people to leave the JWS all together.
