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

  • I make calls about how things will go all the time, but I never write them down or check them after
  • My guesses never seem to get any better because I make them, find out the real answer, and then just move on
  • I’m late on something, I shrug, update the calendar, and immediately forget I ever thought it’d take half as long
  • When I’d swear I know roughly where a number lands, the real answer is constantly outside the range I’d have bet on
  • There’s one area I consider myself an expert in, and that’s exactly where I’m most stubbornly sure and most often wrong

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. 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.

  3. Track your estimates and calibrate
    Compare your Fermi estimates to actual figures when you can, and use the gap to improve future estimates.

  4. Log actual vs. estimated time for every task
    Build a personal database of your own estimation errors so you can calibrate future predictions.

  5. Practice confidence interval estimation
    Estimate ranges for factual quantities and check how often the true value falls within your range.

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

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

  8. Maintain a scored prediction log
    Record predictions with explicit probabilities and score them when they resolve.
    Calibration Training
  9. Practice probabilistic calibration by tracking your predictions
    Assign explicit probability estimates to your predictions and track whether they come true at the right rate.

  10. Calibration practice
    Predict your performance before each retrieval test, then compare prediction to outcome.
