Decision Making can come from 2 parts of the brain, Conscious and Unconscious.
When it comes from the conscious part, theory, story, and explanation are logical, based on step by step analysis.
But many times, the snap judgment that comes from the adaptive unconscious part, "the secret locked door part of the brain", thin slicing experiences, explaination usually comes from assumption with no real facts and figures, an assumption made from previous life experience. (Survival Instinct?)
Why people don't really know what they want? Why thinking about it, they want one thing. And when doing it, they accept to want other thing. (Adaptation?)
Why is it just plain better to learn from seeing and hand on experiences? Ask any Pro to give verbal instruction, and it just doesn't feel right.
Sometimes, it is better to say "I don't know" than make up a plausible cases?
Based on my trying to understand of The Locked Door, 2. The Storytelling Problem (Blink, page 62)
