Janja Lalich, PhD, is a promising candidate. She is the author of the book, "Bounded Choice..." in 2004. An extract from one of her case studies,
"...charismatic authority, the transcendent belief system, the
system of control, and the system of influence. The result of this interactive
dynamic is a “self-sealing system,” that is, a social system that is closed to
disconfirming evidence and structured in such a way that everything reinforces
Charismatic Authority - The WTS would claim they don't have a "charismatic leader" like other cults, but I would argue that the Governing Body is revered and respected without question in the same way.
Transcendent Belief System - it offers a total explanation of past, present, and future, including a path to salvation. Well, yes, the WTS offers that. Exiting believers are often lost afterwards, lamenting "where else" will they get the Truth (TM)?
Systems of Control - includes the overt rules, regulations, and procedures that guide and control members’ behavior. God, there's enough of those!
Systems of Influence - the network of interactions and social influence residing in the group’s social relations. I've watched a study graduate from t-shirt, to dress shirt, to shirt and tie within a few months. He is treated kindly throughout, but there is no question from the congregation's point of view that he will eventually conform.
All very good to understanding the inner workings of high control groups. But how does an outsider provide any sort of alternative? How can they help their loved-ones wake up from the dream/nightmare, consider a simpler mode of living outside the influence of the group?
