It can't be emphasized too strongly that the method of study consists in answering the questions at the bottom of the page in whatever publication they are using. The answer is found in the corresponding paragraph. So, you really end up giving their answers to their questions. If you have attended any meetings, especially the Watchtower Study, you have observed them answering questions parrot-like. This is what you would be doing in your own home if you study with them. It's the closest thing they have to actual "brainwashing," but technically I don't consider it such. I'm sure that many people, if they had read a few publications through on their own rather than allowing themselves to be led step by step in a study, would not be JWs today.
