In my heyday, I read it all--except the Yearbooks, I didn't read most of those. (Did read about the Malawi history in the Yearbook, though...)
I believed my spirituality was directly linked to how much of the literature I read. Probably much of why I ended up getting ousted is BECAUSE I read the literature and noticed just how out of touch with reality the Society really was and is. And I always noticed little peculiarities. Eventually, it was like being raked over the coals or it was just boring. Once I woke up to reality, I found myself terrified of falling asleep during a convention and waking up reassimilated. I never dozed off at any of the events again.
I think if you read the literature, you would eventually find the inconsistencies. But that in itself is not always enough to wake you up. But to the extent possible, I definitely read it.
