"It is important to understand that in most Bible-based cults, although the member is aggressively taught doctrine, it is not the doctrine that holds him in the group. It is the sense that the group is God's true people, a feeling cultivated by techniques of mind control. Thus, to engage the cult member in a Biblical argument or discussion is often futile." Stephen Hassan Releasing the Bonds p.145
Control is not about the teachings, it is about the concept that they are a special people. I think the GB are becoming more aware of that, and so have cut back on heavy doctrine, and now push more the idea that they are the chosen ones, and there are no one else on earth like JWs. The doctrine are basically just filler to make the religion look legitimate.
