I've come to several conclusions.
Being a JW is a lifestyle first and foremost. The esoteric doctrine and theology which gets thrown around and which is so hard to fathom for people "outside" is not that big of a concern for JWs in some ways, which may seem somewhat counterintuitive to us given its emphasis in their literature. Many are quite happy to go with the flow and be considered a JW according to the core practices as defined by the WTBS (field service, meeting attendence, no part of the world etc). Some of these essential practices are corporate in nature and not necessarily religious. There is this strange tension between the WTS as a corporation and the JWs as a religion, given that the two are so tightly intertwined.
They are not interested in launching an in depth investigation of their own religion. And even those who know their stuff relatively well and a bit of the history (quite rare indeed) are not interested in any kind of profound analysis of the JWs which might lead to any reflections which are not religiously approving of the org. They have very little frame of reference.
They will not get into any sorts of analysis of the politics behind doctrines or power struggles either in the present or the past. I think most are not even aware of looking through that kind of lens at the org. It would be totally foreign to them.
I also found that witness perceptions of themselves and their organisation are often conditioned by their daily reality, their routines at the kingdom hall etc. Many have no clue of the how the higher levels of the org function, or any sort of complete understanding of how the whole power structure functions in reality.
In a sense, it almost pays to be ignorant to be in good standing. Otherwise, if you really knew how things went down both in the present and in the past, ie. the power struggles, the connection of doctrine development to specific individuals, the duplicitousness and carelessness, the wackiness of it all, how could you be a true believer? You would need a critical sense to begin with to be able to analyse the org in the this way, which is not what they want.
How can an organisation which abhors higher education and is suspicious of scholarship produce a disinterested account of themselves? It's ironic but they do not know even know who they are, and it's by design. I've always thought it would take intelligent ex JWs to write a decent history of the JWs.
