A surprising number of JWs don't read the Watchtower. To me this is baffling, because if you have the truth, how can you not bother to read it? If this is so life-saving and vital to share with others, why aren't you reading it yourself?
It shows, at least for me, when I was on my way out of the JWs and brought up things that were repeatedly mentioned in literature. Like in the Revelation book, the anointed being referred to as "the John class". My mom, who was an adult at the time we first studied this and was presumably in attendance for the other times the book was studied, seemed to have no idea what I was talking about. You know how many times the term "John class" was used in that book?? You would have to have not read it at all to miss it.
Even in my own experience, personally, after we studied it at the meeting, it was pretty much erased from memory. For the most part, I usually didn't want to go back and reread those articles after we studied them (though I did save a handful of them that were 'encouraging' in my fight against my sexual desires. I still lost, though...).
It makes you wonder how much they really know about this religion at all, from its teachings to its history to its leadership. If you're not reading the literature, it would have to be a very basic knowledge at best, unless you're just mostly reading the Bible by itself (tsk! tsk! sss! You're not going native on us, are you? Independent Bible reading? We better watch you. Your talk just got reassigned until we're sure your doubts are gone...).
