StarryNight: A whole family is really weird... even if they somehow got into a religious frenzy.
Actually, I think that a family is more prone to this kind of behavior just because of how family dynamics work. A family, after all, is a micro cult - a JW family is a cult within a cult.
Shared delusions become amplified in isolation (this family spent three days in isolation - watching movies which were likely JW videos - not eating...) and...boom. the "campfire ghost stories" aka "borg bunker stories" became their reality. They acted on their reality - their true belief in what their religion has taught as the "truth".
I am with Cofty on this - I find it fascinating.
And I also suspect that this event makes lots of people a little uncomfortable and left asking themselves if they may have acted similarly at one time during their true belief stage.
What would it take to tip over into irrational behaviour based on irrational beliefs?
