The term cognitive dissonance is thrown around often on this forum, and rightly so, IMO. It has been discussed before and will be discussed going forward, but another thread made me realize that perhaps now is a good time to re-open the discussion.
In brief, cognitive dissonance is how our minds work to close the gap between our ATTITUDES and what we BELIEVE to be true, and what we DO and EXPERIENCE to be true. Our minds want to close that gap, or reduce the dissonance.
So if what we BELIEVE doesn't match with what we're DOING, we shift our minds to close the gap. Hence we BELIEVE that what we're DOING is correct.
It's the perfect breeding ground for a hectic activity-based cult.
We all experience some dissonance in everyday life, but seldom as much as a lifelong JW who has given up everything and gone out in field service and raised their families with the BELIEF that the world is about to end, and cannot reconcile that belief with the FACT of the awesomeness of the planet and its people and the unlikelihood of the imminent "end of the world".
