I don't think we will see those symptoms within the GB. They are acting in a rational way, tightening their grip and doing damage control.
But, among believers, definitley yes. It would be disasterous if they reacted emotionally on every change in teaching. So, yes, I think we can observe a lot of isolation/compartementalization.
In the long run, this probably will result in some symptoms, maybe depressive.....feelings of emptyness etc. If the cognitive dissonance ( in a way a defence mechanism) can't protect/defend the beleivers self-images this in the end can maybe be a psychological "time-bomb". Hmmm...I hope I'm wrong.
