The multi-year geopolitical forecasting tournament sponsored by the research arm of the US Intelligence Community (IARPA) that led to the groundbreaking discovery of “Superforecasters” ended in 2015. Since then, public and private forecasting platforms and wisdom-of-the-crowd techniques have only proliferated. Six years on, are Good Judgment’s Superforecasters still more accurate than a group of regular forecasters? What, if anything, sets their forecasts apart from the forecasts of a large crowd?
A new white paper by Dr. Chris Karvetski, senior data and decision scientist with Good Judgment Inc (GJ Inc), compares six years’ worth of forecasts on the GJ Inc Superforecaster platform and the GJ Open public forecasting platform to answer these questions.
Key takeaway: Superforecasters, while a comparatively small group, are significantly more accurate than their GJ Open forecasting peers. The analysis shows they can forecast outcomes 300 days prior to resolution better than their peers do at 30 days from resolution.
Who are “Superforecasters”?
During the IARPA tournament, Superforecasters routinely placed in the top 2% of accuracy among their peers and were a winning component of the experimental research program of the Good Judgment Project, one of five teams that competed in the initial tournaments. Notably, these elite forecasters were over 30% more accurate than US intelligence analysts forecasting the same events with access to classified information.
Dr. Karvetski’s analysis presented in “Superforecasters: A Decade of Stochastic Dominance” uses forecasting data over a six-year period (2015-2021) on 108 geopolitical forecasting questions that were posted simultaneously on Good Judgment Inc’s Superforecaster platform (available to FutureFirst™ clients) as well as the Good Judgment Open (GJ Open) forecasting platform, an online forecasting platform that allows anyone to sign up, make forecasts, and track their accuracy over time and against their peers.
The data showed:
