20 Inspiring Quotes from “Thinking Fast And Slow” by Daniel Kahneman


Thinking, Fast and Slow outlines the two most prevalent techniques our brains use. Our brain, like a computer, is made up of systems.

System 1 is quick, intuitive, and emotionally charged. Daniel Kahneman wants us to wean ourselves off of this system. The most prevalent source of errors and stagnation is System 1.

System 2 is a more careful, slower, and logical reasoning process. Kahneman advises using this system more regularly. In addition to this counsel, Kahneman explains how and why we make decisions.
