Aristotle counseled us to seek precision insofar as the nature of the subject permits. But how much is too much? This article provides the first systematic test of long-standing debates about how precisely foreign policy analysts can estimate probabilities. Using a data set of 888,328 forecasts drawn from a series of geopolitical forecasting tournaments, we demonstrate that qualitative probability assessments, including seven-step scales employed by U.S. intelligence analysts, systematically… Expand

Superforecasting reality check: Evidence from a small pool of experts and expedited identification
Supportive empirical evidence from an experiment with an initial (small) pool of 314 experts and an identification phase of (just) 9 months is provided, and preliminary evidence that even an additional training of just 20 minutes, can influence positively the number of superforecasters identified is found.
