here are some techniques I have seen JWs use to manipulate people:
1. invent an ideal fantasy being.... the JW mentioned in the watchtower and awake.... he is everything a JW "should be" and totally inhuman...
he goes to every meeting, he spends every waking moment either studying watchtower materials or in field service. he does not allow selfish thoughts like pursuing hobbies or a better paying job interfer with his eye on the prize of pleasing Jehovah in everything he does and thinks. He does not party with weaker brothers but encourages them to join him in field service. he is a regular pioneer who lives with the modesty of a monk and works just enough to support his basic needs. He is willing to do anything the elders ask of him with a smile. he is a happy worker drone in the anthill of God.... he questions nothing the society says, ever, but diligently make sure of all things by reading their pronouncements into the bible texts given him.
this ideal is deeply planted into the pysche by repetitions in all literature and meetings so that everything one does and thinks of doing is automatically compared to this ideal JW and guilt is generated... guilt which makes one feel inadequate and inferior and unworthy, so that no thought of questioning can enter the mind, as this would only come from satanic whispers to avoid what one must do.
2. just about everything is spoken of in the negative.... do not do this, avoid that, shun this and sprun that.... this technique is very crafty and hard to see as such as so many parents use it and it is found just about everywhere... but here is how it works.... but phrasing things in the negative the only imagery triggered in the mind, the experiences, are those you are being told NOT to think about.... not to act on, not to entertain... like do not think of pink elephants.... it forces you to do the very thing you are being told not to do...its a very subtle trick, as it causes a tremendous amount of guilt as you cannot help but think on these things...and even though you are telling yourself not to do them, the simple act of thinking of them is making them so much more desirable and tempting...as your body tries to follow what you are minding. Just about every parent knows the best way to get their child to do something is to:........ you can all fiinsh that can't you?
3. the disfellowshipping or shunning combined with the tests to become a JW in the first place make the group look like a very exclusive club which only the "right" people can belong.... over and over the JW is told that they are there because they and they alone have the "right" stuff and that there may be others in the world who are like them and need to be gathered out before it is too late... but that the road to destruction is filled with the rest who do not have the "right" stuff...the weeds, the goats, the resistant [satans]...these are easy to identify and avoid... they are cynical and rebellious and always talking mean and nasty when it comes to God, Jesus, and JWs.... no great amount of thought is required to identify "them" and of course anyone who leaves is anti-christ according to John, they were not of our sort, they were only pretendning, working with some date in mind out of fear, not the love of Jehovah, etc.
