You don't actually think that JWs study the Bible do you? I know that even at my most zealous period in life I barely had time to prepare for the meetings, read the magazines, and read my bible daily. There was little time for deep research and thinking about the scriptures. The scriptures used for the meetings are selected to support whatever point they are trying to get across. Few JWs do more than look up the selected scripture and try to apply it to the paragraph.
Even those that read the Bible daily do so with blinders on. When I read the Bible as a JW, I was always thinking how the passage would fit to our understandings rather than thinking about the passage itself. When I started meditating on what the scripture meant and the context, that's when I started to see how JW understandings didn't line up.
