… But when people make non-falsifiable predictions, they feel less accountable. After all, if a prediction can never be disproved, then it poses no reputational risk. That lack of accountability, in turn, encourages overconfidence and even more extreme predictions.
Non-falsifiable predictions thus undermine the quality of our discourse. They also impede our ability to improve policy, for if we can never judge whether a prediction is good or bad, we can never discern which ways of thinking about a problem are best.
The solution is straightforward: Replace vague forecasts with testable predictions. CONT.
