Our professional Superforecasters have tackled hundreds of forecasting questions since 2015. The statistics below summarize average performance over the 277 questions that have “resolved” (in other words, questions for which the outcome is known) as of November 13, 2020. For purposes of this analysis, the “correct” outcome means the answer option that actually occurred and resolved the forecasting question.
We’ll update this information periodically as additional questions close.
