I think this exists in many religions. Many of the WT derision of Catholic practices were never sanctioned by the Roman Catholic Church but were local folk practices from the indigenous cultures blended with Catholic teachings.
Quantity of hours rather than quality of understanding is stressed. I love reading something and then meeting with others to share our interpretations. If I dsagrew with someone, I clarify why not believing their side is so important to me. Patterns emerge. I've been part of a culture where hard questions are worshipped so I ask or comment. So many times people will break in and say they wondered about the same thing but were afraid to ask. As I've said before, I don't believe college is about fact accumulation. Analyzing the data is the important part. Acknowleding the weaknesses in your position is also crucial.
In order for rank and file members to understand WT theology, much more time would have to be spent in individual study. Not answering questions such as the WT prints, but real discussion. Mainline churches no longer do this unless someone is very interested. It is time intensive. All the rank and file must do is memorize scripts.
I am Anglican and no church official believes your soul floats around in heaven when you die. Rather, they believe that God can reform you with a new body that is still you. This part is a bit messy. Most Americans believe your soul goes to heaven or hell. They say so to priests at funerals. The priest does not correct them. Something consoling is said. The priest does not agree with the person, but the person doesn't realize there is a difference. It may be discussed later but not during a funeral.
The number of Witnesses who purchase concordances, encyclopedias, advanced study materials, etc. amazes me.
In the pragmatic life of a KH congregation, knowing too much about Witness theology is only going to cause you trouble. An elder might be threatened. You may be correct but your life will not be pleasant.
