> Deliberately suspending one's beliefs takes very good storytelling and/or resources corresponding to a movie budget
I think the "cost" entirely depends on the frame in which the truth is held. It is my belief/hypothesis, that internally visualized truths are cheap to be "rational" in the internal frame. Out here, in reality, those "truths" become irrational, i.e. a lot of expensive work must go into manifesting those truths in the "hardness" of reality.
Irrational truths can manifest "on the cheap" here, I think, if they don't involve speaking for other's truths. Sticking to your own vision, for yourself (or a god), seems to be a common teaching across multiple religions and philosophies. Maybe groups can manifest things cheaply here if it is a common truth for a large amount of the group (and only one or two groups).
I appreciate someone else knows about dissonance. It's a powerful force, when involved in complexity.
