The central idea of the incerto is that when you have uncertainty in the system, it makes your decision making much, much easier. And people behave that way because they don't know what to do if there's no certainty about something. For example: If i tell you I'm not certain about the quality of this water, would you drink it? No, look, it very good. Ois, very simple. We're got to see how people's built-in instincts are vastly super over scientists' knowledge.
