In the last meeting I attended the CO kept on emphasizing the need to be humble and follow the FDS. All the pieces came together at that point and I walked out never to step into a kingdom hall again. There is definitely a theme.
I never thought about the Q and A format of watchtower studies and bible studies until this post. It's similar to doctor-patient or teacher-student interactions. It's really a script that you aren't allowed to deviate from. You're assuming the JWs are an authority and you mindlessly follow this process. Not long ago I actually attended a religious workshop of sorts and there was an actual dialogue and back and forth of ideas with the people attending asking challenging questions. In most circles, the burden of proof lies on those presenting the information, but with JWs your character is attacked if you ask too many questions (see Wake Me Up's earlier post) or your redirected in a way so that the conductor continues to have control and hold the floor.
I also think that JWs are similar to other "truth seekers" and conspiracy theorists that somehow believe that they are special because they understand something or know something that no one else gets. So it feeds your ego - there's a payoff. jah "chooses" the humble ones to share this special information and secrets with.
I'm interested to see how your research develops.
