I was raised as a JW and left when I was twenty. I do not ever recall anyone who had a doctorate level degree in any of the professions. The more knowledge you have the more you tend to scrutinize and ask questions. For the JW's that is usually the beggining of the end. You either get removed for asking very pointed questions or see the hyprocrisy and just leave.
IMHO that is the real reason they discouraged a college education for so long. I am surprised to have learned that they once again reversed that. It does not seem to be in thier best interests.
The WTS can not stand up to even a very simple cross examination which could explain so very few attorneys being JW's.
