Kahneman continues by explaining that we can think of our brains having two controlling systems, an intuitive system and a rational system. The intuitive system is fast, quick to make judgement and desperate to make a complete story to tell the slower, heavier processing rational system. It seems we have a general tendency to favour the intuitive system and only when this fails to make sense of what we see we use the rational system. In order to keep us processing quickly we use little stories, well-known to us that are similar to the experience at hand. Even when we do not have a complete picture this system will create a story so convincing that we feel that it is real so that our rational system is convinced it doesn’t need to engage. This is why we feel so many situations are familiar. This is why we need stories.
