First of all, nothing about the WTBTS is intellectual. You simply have to disabuse yourself of this false notion.
I will concede that they are big on the appearance of "biblical scholarship," but the facts prove otherwise. Why do you think the WT leadership is so against higher education for their followers?
There are several reasons, but one of the main ones is that anyone with even a modicum of education as to how real scholarly research is conducted will quickly realize that no WT publications even come close. The average WT is written at what would be the 7th grade level in the United States, that is at the average level of a 12 - 13 year old child. Hardly the stuff of intellectualism.
Even the few publications such as the Creation book or the now abandoned Trinity brochure which seem to be well-researched and academically sound are shams. Both have been soundly trashed for their flagrant misuse of quotes.
What I believe you are really wanting to address it the way the WT leaders use a variety of techniques of psychological manipulation. They are, in fact, experts at it. To my mind, their prowess in manipulating people with sophisticated and subtle means is evidence of their deliberate and knowing intent. They are morally culpable. Whether or not they actually believe any of the bullshit doctrines the profess is debatable. However, I believe it is self-evident that they are fully aware of their deceptions and lies and just don't care.
You might find this older thread useful in your self-education on the topic:
Indeed, I would encourage everyone at your stage of coming out of this cult to read all three articles in this Awake! series on propaganda.
The Awake! articles on propaganda are in the June 22nd, 2000 issue. Here's the link:
http://wol.jw.org/en/wol/lv/r1/lp-e/0/19944
It's the first three articles:
* Propaganda Can Be Deadly
* The Manipulation of Information
* Do Not Be a Victim of Propaganda!
They're very educational and, at least for me, are conclusive proof that the WT writers absolutely know what they're doing and are both very skilled at it and very deliberate.
Ya' gotta' love the irony of the third title!
KateWild: Is it impossible for WT to recruit a intellectually strong individual?
Not only is it possible, it is likely.
According to Steven Hassan, intelligence is not a protection against being recruited into a cult. In fact, intelligent, creative people are in some ways easier to indoctrinate as they can intellectually fill in the fantasy with their own imagination.
The only protection is knowing the techniques of mind-control and manipulation and recognizing when someone is trying to use them on you.
(Sorry I don't have a citation for you; I've read two of Hassan's books, almost everything on his website and watched many of his videos so I don't remember exactly where he said this, but he has made this point repeatedly.)
