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

• 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
• The question is so big and tangled that I just go with my gut and blurt out a number, and it feels like a guess because it is one
• I make calls about how things will go all the time, but I never write them down or check them after
• New information keeps arriving that should obviously move my estimate, but I just cling to the date I first committed to
• When a prediction of mine blows up, I either spiral into thinking the whole thing is pointless or I just shrug and forget it

Practices that may help

1. Maintain a scored prediction log
   Record predictions with explicit probabilities and score them when they resolve.
   Calibration Training
2. Decompose complex questions into sub-questions
   Break a hard forecasting question into smaller, estimable pieces and aggregate them.
   Superforecasting
3. 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.
   The Outside View
4. Update your forecast incrementally as new evidence arrives
   Treat your forecast as a probability that should shift with each new piece of evidence, not a commitment that survives contradiction.
   Reference Class Forecasting
5. Treat forecasting accuracy as a skill that improves with practice
   Take prediction errors as performance feedback, not as proof that forecasting is futile.
   Superforecasting
6. Reference Class Forecasting
   Reference class forecasting, developed by Daniel Kahneman and Amos Tversky and formalized by Bent Flyvbjerg, improves forecast accuracy by anchoring on the statistical distribution of outcomes for similar past projects rather than on the details of the current one. The method reliably corrects the optimism bias that inflates cost, time, and benefit estimates in planning — the evidence base here is real and specific.
7. Forecast a distribution, not a point estimate
   Represent your forecast as a range of likely outcomes, not a single predicted number.
   Reference Class Forecasting
8. Track the accuracy of your domain predictions
   Keep a record of what you predicted in your area of claimed expertise and score it.
   The Dunning-Kruger Effect, Understood Clearly
9. Track your calibration across many predictions
   Score your confidence levels against outcomes over dozens of predictions to find your systematic biases.

10. Conduct post-project debriefs to contribute to the class data
    Record actual vs. forecast outcomes honestly — this builds the reference class that future forecasts depend on.
