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

  • My confidence comes straight from how good a story I can tell myself about this particular case, and the more vivid the story the surer I get
  • When I’d swear I know roughly where a number lands, the real answer is constantly outside the range I’d have bet on
  • Everyone tells me to "just believe in myself more," but I’m not sure pumping up my confidence is even the right fix
  • 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 tend to blurt out one confident-sounding number and act like it’s solid, when honestly I have no business being that sure

Practices that may help

  1. Anchor your confidence level on base rates, not gut feel
    Start your confidence estimate from the historical hit rate for this type of prediction, not from how confident you feel.
    Calibration Training
  2. Practice confidence interval estimation
    Estimate ranges for factual quantities and check how often the true value falls within your range.
    Calibration Training
  3. Pair confidence work with honest, accurate appraisal of your actual standing
    Confidence without accurate self-assessment is overconfidence — the goal is calibrated self-belief, not boosted belief.
    Power Posing Revisited
  4. Maintain a scored prediction log
    Record predictions with explicit probabilities and score them when they resolve.
    Calibration Training
  5. Estimate in ranges, not point estimates
    Instead of "my estimate is 500," say "I think it is between 200 and 2000."
    Fermi Estimation
  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. 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.
  8. Track your estimates and calibrate
    Compare your Fermi estimates to actual figures when you can, and use the gap to improve future estimates.

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

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