Key ideas in Why We Do What We Do

  • The habit loop consists of a cue, routine, and reward
  • Habits shift from the prefrontal cortex to deeper, automatic brain structures
  • The cue is the specific trigger that initiates the behavior
  • Repetition creates a pre-programmed loop that bypasses conscious choice
  • The cue must precede the routine
  • The reward is what reinforces the loop for future repetition
  • The sequence of events that leads to a habit becoming 'stuck' on repeat
  • The brain is an energy-intensive organ that seeks to conserve metabolic resources
  • Deep analytical processing is slower and more 'expensive' than using intuitive shortcuts
  • Heuristics are the mental process, while biases are the resulting errors in judgment
  • Specific shortcuts lead to predictable patterns of miscalculation
  • How specific shortcuts manifest as common cognitive biases
  • Shortcuts help us make fast decisions in high-stakes or busy environments
  • Why the brain prioritizes energy efficiency over accuracy
  • The brain often filters out 'contradictory' data to maintain a consistent mental model without extra effort
  • How the brain transitions from conscious decision-making to automatic habit execution
