The point I am making is not whether humans can be logical , but whether this alone can motivate people to change strongly held belief systems.
I can agree with that, Sleepy, but only up to a point.
I'd also like to amend something I said earlier. I said, "As it applies to JWs, when it comes to them remaining loyal to the organization, neither logic nor emotion is ever the deciding factor." I was probably wrong saying that.
Many, many people remain JWs exactly because of emotion. Some, like my mother, are very emotional in her support of the WTS and often their defense of it is totally absent of a single shred of logic/reason. On the other hand, those who HAVE employed logic to come to an understanding of all the lies/misinformation behind the Wt Corp. still are victims (willingly or otherwise) of emotion. They realize that to leave would mean a severing of ties with loved ones, so emotion is part of the equation with them.
I think this amended statement agrees with yours above. I will say this: over time, logic will affect one's emotions. Logic will eventually lead one to be less and less emotional about a matter, particularly if one's emotional attachment to a thing is seen to be not in one's best interests.
Tell me... what is the "magic bullet" to which you refer? I should have asked for clarification at the outset.
Peace,
