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

  • When I’d swear I know roughly where a number lands, the real answer is constantly outside the range I’d have bet on
  • When I say I’m eighty percent sure I genuinely don’t know if that means anything
  • There’s one area I consider myself an expert in, and that’s exactly where I’m most stubbornly sure and most often wrong
  • I make calls all the time but I never write them down or check them later, so my confidence is just a feeling that floats free
  • I’m sure about things constantly and I have no idea if that confidence is earned

Practices that may help

  1. Calibration Training
    Calibration training teaches you to match your stated confidence levels to your actual accuracy: if you say "70% confident," roughly 70% of those claims should turn out to be correct. Tetlock’s forecasting research and probability training studies show calibration is trainable with practice and feedback — the evidence here is specific and replicable.
  2. Practice confidence interval estimation
    Estimate ranges for factual quantities and check how often the true value falls within your range.

  3. Practice calibration by tracking your confidence predictions
    Your "80% confident" beliefs should come true about 80% of the time — check that they do.

  4. Identify the specific domains where you are most overconfident
    Calibration is domain-specific — find where your confidence most exceeds your accuracy.

  5. Maintain a scored prediction log
    Record predictions with explicit probabilities and score them when they resolve.

  6. Practice probabilistic calibration by tracking your predictions
    Assign explicit probability estimates to your predictions and track whether they come true at the right rate.

  7. Estimate in ranges, not point estimates
    Instead of "my estimate is 500," say "I think it is between 200 and 2000."

  8. Score your own past predictions to calibrate your outside-view use
    Keep a forecast log and score it — you cannot improve calibration without feedback on where you were over- or under-confident.

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

  10. Build calibration reps with low-stakes trivia and almanac questions
    Use factual trivia questions as a practice ground for calibration — outcomes resolve immediately and the stakes are zero.
