Forecasting Failures Share One Hidden Mistake

The article argues that nearly every major forecasting failure of the last 20 years shared the same hidden mistake, citing economists missing the financial crisis and energy planners as other examples. It presents a recurring error across fields that the author connects to those high-profile forecasting breakdowns.
