  1. Thinking, Fast and Slow, Made Usable
    Daniel Kahneman describes two modes of thought: System 1 is fast, automatic, and intuitive; System 2 is slow, effortful, and deliberate. Better decisions usually come from noticing when a problem deserves System 2 and deliberately slowing down — though some popular claims from the book (notably certain priming studies) failed to replicate.
  2. Notice which system is driving
    Before deciding, ask whether this is a System 1 (snap) or System 2 (effortful) problem.

  3. Slow down for high-stakes, irreversible decisions
    Match deliberation to the cost of being wrong: spend System 2 where reversal is hard.

  4. Distrust easy fluency
    Treat "this feels obviously right" as a flag to check, not a signal to proceed.

  5. Reverse and Rearrange
    Ask: what if the sequence were inverted, the roles were swapped, or the normal order were reversed?
