Misery you bring up a hard point.
It's not just the Witnesses that are trying to keep their members in perpetual youth, I mean look at the BORNagains. If you can get someone to choose perpetual immaturity then you now have a specifically subservient person, almost like you get to the point where you can just "nudge" them in a direction of your choosing.

And that's exactly what both Jesus and early Christians were getting away from! The Jews were harnessed by the law and the traditions of their religious leaders. As a result, they were incapable of reaching their full potential as a nation set aside from all other nations before God. Later, that same immaturity was present when Paul wrote to the Hebrews and he likened them to babies incapable of eating solid food. It was if they regressed back to the role of a Gentile, just developing a faith for the first time.
Its the same thing with JWs today. The organization doesn't want individuals thinking, reasoning, discussing, ect.. They want indoctrination, and then repetition. Its the reason the WT study and other Q & A parts are the way they are. You read the paragraph, the question paraphrases the answer in the paragraph, you underline the answer. You attend the meeting, the reader reads the paragraph, the conductor reads the question which paraphrases the answer, then someone comments by rephrasing what was written in the paragraph and substituting a word or two. Its all about repetition.
When you think about it, there's more debate and research done on this forum, then the Writing Department does at Bethel. Half the WT articles rehash previous articles, and even pictures from old literature is republished into new literature. Its a perpetual state of repetition, without any advancement.
