Hi Joe,
This is something that I have given much thought to. I have researched the work that has been published by leading cult experts such as Robert J. Lifton, Margaret Singer, and Steven Hassan. I have found many striking similarities between the Watchtower indoctrination process and what cult experts call "mind control". However, this does not mean that Jehovah's Witnesses are necessarily a cult.
Steven Hassan, in his book: Combatting Cult Mind Control explains that many organizations (even secular) can exhibit a few characteristics of cults without really being one. Hassan points out that the Communist Party under Mao exhibited several cult-like characteristics, although few people considered the Communist Party a cult. The truth is, the word cult is a very ambiguous label that can be slapped on just about any unorthodox organization that has strange practices. I have heard many fundamentalist Christians label the Mormon Church, the Salvation Army, Alcholics Anonymous, and the Church of Scientology all as "cults". But sticking a label on something doesn't always make it so.
I strongly believe that the Governing Body truly believes that they are doing what's in the best interest of the "flock". They truly believe that they are the "Faithful Slave" entrusted with the heavy responsibility of protecting the "flock" from all outside, "worldly" influences. I believe that because of this heavy responsibiltiy and pressure; they have been lead to to micro-manage the congregations as well as Witnesses lives. I think a good analogy is a parent who is trying to protect their child from outside dangers. We all know that there are parents out there who have very irrational fear and attempt to shield or cocoon their children from every little danger; not because the parent is sadistic, but because their love coupled with irrational fear makes them do some irrational things. This may sound as if I am trying to be an apologist; but I am not. I am simply being rational and objective. As Raymond Franz points out in his book: Crisis of Conscience, what has often plagued mankind in religion the most; is not the carefully contrived lie, but is often the deeply cherished and inherited myths. He pointed out that the current Governing Body did not invent the doctrines of 1914, the "Faithful and Discreet Slave", and "Salvation by Works"; they inherited them from Rutheford.
There is however, some very strong threads of "mind control" that run through the Watchtower publications and indoctrination process. As Steven Hassan points out; mind control contains elements of "loaded language', "thought-stopping cliches", and psychologically coercive images (i.e. Watchtower illustrations of people being destroyed at Armageddon)
As I recommended in a previous posting, you should do a Google search under Robert J. Lifton, Margaret Singer, and Steven Hassan. These three experts have published some excellent research into cults and the science of mind control. Their research is very enlightening.
I also recommend reading the work of Randy Watters (a former Witness and Bethel Elder) on his website:
He has written extensively on Watchtower mind control and other JW psychological issues.
