Thinking, Fast and Slow book summary

The topics that Nobel Prize winner Daniel Kahneman addresses are both complex and integral to the human mind: He asks you to think about thinking by considering how your mind habitually contradicts itself, distorts data and misleads you.

System 1 takes over your thinking when you comprehend simple statements (such as “complete the phrase ‘bread and . . .’”), instinctively turn to see where a noise is coming from or grimace when you see a gruesome image. System 1 supplies associated meanings (including stereotypes) rapidly and involuntarily.

By contrast, you use “System 2” when you’re focusing on specific details, like counting or figuring out how to complete your income tax forms. System 2 applies effort consciously, such as when you do complicated math, try new physical activities or search for a specific person in a crowd. System 2 thinking is slower, but you need it for methodical thinking processes such as formal logic.

Human beings tend to value the measured System 2 while dismissing the mechanical System 1, but reality is much more complicated. ...

    Prospect Theory is really a key topic that I think would have been good to include in a little more detail in this summary.
