I was thinking of the sheer number of times the JW's have gone through the Revelation book. I guess most of that goes right over the head of someone studying with JW's (?)
I tend to believe that the Watchtower purposefully makes those books confusing. I remember being an unbaptized publisher, reading through the revelation book. I understood none of it. I believe I actually read the book before me and my study conductor came to the information about the 'faithful slave' in the Knowledge book. When we went over that FDS stuff, I had no idea what he was talking about, even though I had actually read that revelation book! It just goes right over your head.
I can only use my own experience, but from what I remember a new convert is so fixated on the "important things" (i.e. hellfire, trinity, paradise, ect) that anything complicated or strange gets set aside. You really don't notice the strange stuff.
I agree with your analysis, but I've looked at it a little bit differently. From my perspective, it's the buy-the-whole-ranch-because-you-like-the-cow syndrome. A potential convert becomes throughly schooled in the flaws of the major Christian denominations. Long-held articles of faith such as hellfire, the trinity, heavenly hope for all the faithful are attacked from every angle while the flaws in JW doctrine are ignored. The potential convert becomes convinced that all of the other major religions have it wrong, so therefore JWs must have "the truth."
I agree with your assessment, it is basically how I felt when I converted.
I will add that the potential convert probably never believes that the JWs have "flaws" per se. New converts tend to be idealistic, something that is exploited by the JWs. They buy the argument that there are simply things that they don't understand at the moment, but that understanding will come in time. These items get "put on the shelf" for further consideration at a future point in time (which never actually happens).
