JW's have a lot of literature to read & study, meeting to attend that require participation. They practice 'WT-style teaching' at the TMS and in weekly FS.
In the literature, certain words/phrases are repeated again and again. The materials for talks come from pre-scripted outlines. Check out the Reasoning Book. At the end of each topic, supposed FAQ's from the ministry are included. The WT teaches how 'not' to ask answer these questions by either focusing on another related topic or questioning the reason/motive of the person asking.
Don't underestimate the cumulative effect of these teachings and being around people who think/speak/act the same way.
