Superforecasting
Replace certainty with estimates you can test.
Big Idea
The authors argue that forecasting improves through clear questions, probabilistic thinking, revision, and honest feedback.
Answerable Questions
A forecast needs a defined event and deadline so its accuracy can eventually be checked.
Probabilities
Assigning a probability expresses uncertainty more precisely than simply saying an event will happen.
Updating
Revise estimates when evidence changes instead of protecting a prediction made earlier.
Different Perspectives
Teams can improve judgment by comparing information and challenging each other’s assumptions.
Keeping Score
Recorded predictions reveal whether confidence has matched results over time.
- Success on studied questions does not make every distant or unprecedented event predictable.
Khizooo Take
Write down one forecast with a deadline and probability, then review it without rewriting what you originally believed.
Remember
A forecast becomes useful when it can be corrected.
