So, all decisions are not made after a lot of thought, after weighing all the evidence, and using our rational facility. Some are made instinctively, or based on years of expertise, or reading facial movements that we don’t know we are reading. And the rational decision making is not necessarily the best. Sometimes, you should go with your hunches. And there are a lot of examples you can give, and a lot of sources you can cite, to demonstrate this.
This is what you learn from “Blink”. It’s entertaining, yes, and interesting, yes, but not profound. By instinct, I didn’t think I needed to finish it. Should have gone with my hunch.
