Thinking, Fast and Slow

Description

Notes

• we spend most of our time in Thinking, Fast and Slow / System 1
• as result of WYSIATI people make wrong judgements and decisions due to biases and heuristics

Notes

System 1

• intuitive
• based on gut reaction
• forms first impressions
  • that’s the reason why we jump directly to conclusions
• runs automatically
• generates suggestions for System 2
  • impressions
  • intuitions
  • intentions
  • feelings
  • when runs into difficulty, it calls System 2 to support more detailed and specific processing that may solve the problem of the moment
• sometimes answers easier questions than it was asked
  • it quickly creates a coherent, plausible story (explanation for what it is happening) by relying on
    • associations
    • memories
    • pattern-matching
    • assumptions
  • it will think the story is plausible and convenient
    • even though it is based on false information
• has little knowledge of logic and especially statistics

System 2

• analytical, critical thinking
• does reflection, problem-solving and analysis
• is normally in comfortable low-effort mode
• endorses impressions and intuitions
  • turn into beliefs
  • impulses turn into voluntary actions
• activated when an event is detected that violates the model of the world that System 1 maintains
