Cognitive dissonance keeps members in the spiritual netting.
When the JW's manage to get somewhere with someone, they have all these
answers to questions you didn't even think to ask. They seem to have a logical
answer for everything- from Bible skeptics to Scientists to those of other beliefs.
They hold out such a wonderful promise of paradise.
So a person who never thought much about the Bible or God or the future, suddenly
realizes that somebody has done all the thinking about them for him.
As the student progresses, he doesn't agree with all of it, but that creates dissonance
in his mind. The things he does that don't harmonize with the teachings of these
obviously intelligent deep thinkers on the Bible, the things he thinks that don't harmonize,
the things they tell him that he can't understand- all that creates cognitive dissonance.
Cognitive dissonance is defined as the uncomfortable tension that may result from having
two conflicting thoughts at the same time, or from engaging in behavior that conflicts with one's beliefs.
The cognition is the belief or knowledge. Contradicting cognitions serve as a driving force that compels
the mind to acquire or invent new thoughts or beliefs, or to modify existing beliefs, so as to reduce the
amount of dissonance (conflict) between cognitions. (See http://en.wikipedia.org/wiki/Cognitive_dissonance)
The two people who come to his home obviously know more about the subject than he does,
so they are probably right. He even starts thinking that the questions they brought to him are
ones that he has been pondering. And when they get him to the Kingdom Hall, well, there are
about 50 to 100 people who all agree with the doctrine. It makes sense to accept what these
people believe.
Many people who stay as JW's are those that seek information that will reduce dissonance and avoid information
that will increase dissonance. But the WT literature study has them doing it backwards. They are told
where to look for answers, and that's only in the NWT and the WT literature, so eventually the doctrines are
the things they need to harmonize with, while ignoring the doubts against it.
By the time we are that far gone, the outside information that disagrees with WT is totally ignored and
minimized.
