The Two Systems of Thinking

  • There are two systems of thinking - System 1 and System 2. System 1 is "reaction", while System 2 is "analytical",

  • System 1 (Thinking Fast) is the intuitive, reactive way of thinking based on first impression and quick reaction. (Jumping to conclusion), while System 2 (Thinking Slow) is about reflection, analysis and problem solving.

  • We think that we are rational and analytical, but that's wrong. We use system 1 more often than system 2. In a way, feeling that we use System 2 more itself is a result of System 1 thinking. Analyze and you will know you are wrong ;)

  • System 2 only gets involved when we encounter something unexpected that System 1 can’t automatically process.

  • System 1 is accurate at times. But it can make error due to Bias Also, System 1 sometimes answers easier questions than Is this a real problem the real problem
