Does this sound like the set of challenges you might be facing?

  • I keep playing out this decision in my head as if there’s just one way it goes
  • This is a one-way door
  • I make these probability guesses in my head
  • I’m weighing a dozen factors on the same choice I face over and over, and they all blur together
  • I made a call that turned out badly and now I feel like an idiot for it

Practices that may help

  1. Enumerate scenarios and their probabilities before deciding
    Write down each meaningful outcome, assign a probability, and compute the weighted total.

  2. Expected Value Thinking: Deciding Under Uncertainty
    Expected value thinking multiplies each possible outcome by its probability and sums the results, giving a single number that represents the average payoff of a decision. It is the mathematical foundation of rational decision-making under uncertainty — well grounded in decision theory — but it has real limits: probabilities are often uncertain, outcomes are not always quantifiable, and raw expected value ignores risk aversion that can be legitimate.
  3. Use maximin reasoning for high-stakes, irreversible decisions under ambiguity
    Choose the option whose worst plausible outcome is most survivable — when you can’t compute expected value, optimize the floor.

  4. Keep a decision journal to score your EV estimates
    Log your probability estimates and payoff predictions, then compare them to what happened.

  5. Use "take the best": choose on your single most informative cue
    When choosing between options, identify the most diagnostic cue and use it — stop searching for more.

  6. Thinking in Bets
    Annie Duke's thinking in bets framework treats decisions as bets with uncertain outcomes, separating the quality of the decision from the quality of the outcome. Most real decisions involve incomplete information, so good decision-making is about process and probability, not about being right every time. The core skill is evaluating decisions on the information available at the time, not on how they turned out.
  7. Bayesian Thinking: How to Update Beliefs Rationally
    Bayesian thinking is the practice of holding beliefs as probabilities and updating them systematically when new evidence arrives — rather than treating beliefs as simply true or false. The mathematical framework is well established; the challenge is building the habits of explicit probability estimation and honest belief updating that make it practical.
  8. Judge decisions by the process, not the result
    A good decision that produces a bad outcome is still a good decision.

  9. Move fast on two-way doors
    On reversible decisions, decide with 70% of the information you wish you had — then adjust.

  10. Track your calibration across many predictions
    Score your confidence levels against outcomes over dozens of predictions to find your systematic biases.
