Link to video: Daniel Kahneman: Thinking Fast and Slow
Before a packed house, Kahneman began with the distinction between what he calls mental “System 1”---fast thinking, intuition---and “System 2”---slow thinking, careful consideration and calculation. System 1 operates on the illusory principle: What you see is all there is. System 2 studies the larger context. System 1 works fast (hence its value) but it is unaware of its own process. Conclusions come to you without any awareness of how they were arrived at. System 2 processes are self-aware, but they are lazy and would prefer to defer to the quick convenience of System 1.
“Fast thinking,” he said, “is something that happens to you. Slow thinking is something you do.“
