This may be the biggest obstacle that prevents the average JW from addressing their congnitive dissonance. Witnesses are systematically indoctrinated to believe that any unflattering observations they may have about the organization, it's doctrines, or policies originate from a "fault-finding" attitude.
They are indoctrinated to believe that the "seeds of doubt", the "fault-finding attitude", and the "independent spirit" are in a sense, viruses that have been unleashed into the "system's air" by Satan. If one catches these traits developing within themselves, they believe that they must eradicate this "virus" by diving deeper into Watchtower publications and praying for their "bad thoughts" to cease.
Many JWs must also take extra measures to suppress their dissonance with coping mechanisms such as alcohol, over-eating, anti-depressants, and watching a lot of television. Anything to make the thougts go away.
You will find that this kind of overt manipulation used by the Watchtower is also used by toxic parents who repeatedly induce guilt in their children to control them. Children of toxic parents are conditioned to ignore their own deepest needs and desires, and are taught that their own feelings don't matter. They are taught to give their power away.
This systematic process of guilt-inducement by the Watchtower is incredibly toxic and stunts people's intellectual and emotional growth. I have often argued that the Watchtower organization is one of the most toxic parents of them all.
