Coaching practices for Team Forecasting
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Team Forecasting, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- Whenever my team decides anything, the loudest or most senior person’s view just takes over the room and everyone quietly falls in line
- Each project wraps up and I move straight on without ever writing down what I’d guessed versus what actually happened
- I commit to one confident number
- 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 build my estimate from my own optimistic story first and only glance at how long these things usually take at the very end as a sanity check
Practices that may help
- 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. - Use structured team forecasting to aggregate diverse views
Combine independent estimates from multiple people before the group talks — aggregation beats any single expert.
Superforecasting - Superforecasting
Philip Tetlock’s forecasting tournament research found that a subset of ordinary people — "superforecasters" — consistently outperform domain experts and intelligence analysts at probabilistic prediction. They share measurable cognitive and behavioral habits: they think in probabilities, update frequently on evidence, and actively seek disconfirming information. These habits are learnable. - 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.
Reference Class Forecasting - Forecast a distribution, not a point estimate
Represent your forecast as a range of likely outcomes, not a single predicted number.
Reference Class Forecasting - Decompose complex questions into sub-questions
Break a hard forecasting question into smaller, estimable pieces and aggregate them.
Superforecasting - Anchor on the base rate before adding inside-view details
Start your forecast from the class median, then adjust — do not start from your narrative and adjust to the base rate.
Reference Class Forecasting - 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 - Identify the right reference class for your situation
Find a well-defined set of past situations that are structurally similar to yours and collect their outcome data.
Reference Class Forecasting - Treat forecasting accuracy as a skill that improves with practice
Take prediction errors as performance feedback, not as proof that forecasting is futile.
