Gingerbread - For a century they have been telling us that we can come to a true understanding of the Bible ONLY by reading and studying their publications.
BOTR - We were never taught thinking skills. My experience is from the 1950s but I had notes/lit from deceased family members. There had to be self-selection going on in who became a Witness. I thought I knew the Bible and WT doctrine.
Those two comments sum up the situation. JWs have always been forced not to think or research, but rather learn Watchtower doctrine by rote. They forcefully felt they knew more than others, and still do. That does not make Watchtower doctrine right, it is just that most religious people do not know their own doctrine well enough to hold such a debate.
Overall, both JWs and people of other religions are becoming less interested and educated about their own doctrine. That is product of society in general. TV, computers and ipads have led people to short attention spans and information overload. This generation operate off sound bites rather than extensive research.
