Quick decisions and slow ones run on different kinds of thinking. Naming which one you're using helps you know whether to slow down.

  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. The Three-Circle Model: Mapping Your Emotional Systems
    Understand your threat, drive, and soothing systems — and learn which is overactive in your life.
    Compassion-Focused Therapy: Calming the Inner Critic
  4. Anchor Major System words in a memory palace
    Place each Major System word-image at a locus to make long numbers retrievable in sequence.
    The Major System: Encode Numbers as Words
  5. Slow down for high-stakes, irreversible decisions
    Match deliberation to the cost of being wrong: spend System 2 where reversal is hard.

  6. The Major System: Encode Numbers as Words
    The Major System is a phonetic mnemonic that assigns consonant sounds to digits 0–9, letting you convert any number into a pronounceable word or phrase. Those words are far easier to remember than raw digits because the brain handles language and imagery dramatically better than abstract numerals. The system is well established among memory practitioners, though formal RCT evidence is limited.
  7. Build basic nervous-system regulation capacity before SSP
    SSP works better — and is safer — when the nervous system already has some self-regulation capacity.

  8. Map your state (ventral, sympathetic, dorsal)
    Learn to notice which of three nervous-system states you are in before you try to change anything.

  9. Draw or sketch the inner system visually
    Put parts and their relationships on paper — who is close to whom, who holds whom at arm’s length.

  10. Take the outside view (base rates)
    Estimate using the track record of similar cases, not the vivid details of your own.
