It's drummed into your head by the Circuit Overseer, no extra research, even if it is JW literature, and no extra scriptures. We were told that the slave knew all of the extra research that we want to bring out, and the FS decided to leave it out and so should we! "We don't know more than the slave, do we? So leave it on the cutting room floor," was the C.O.'s words.
Wow! I left totally in 2010, but stopped attending meetings in 2007. I always remember people being praised from the platform for doing extra research for the benefit of the congregation. Now members are under strict orders to just be intellectually lazy and only listen to repeat.
