The chapter holds a view introduced by Kahneman as the narrative fallacy. It occurs when people attempt to make sense of the world. The brain focuses on a few things that happened rather than most of those that failed too. Success is a sense built up by System 1 which enables us to see the world as a simpler place and predictable than it is. Hindsight creates a feeling that the mistakes we commit in reasoning are apparent and that you were not in a situation to have known them in advance. System 1 has a way of jumping into conclusion with little sources.
