What are the characteristics of superforecasters? How can a superforecasting team be developed? Hear from Warren Hatch, CEO of Good Judgment, a leading global forecasting business based in NYC. Accurate forecasts from Good Judgment superforecasters have included the scale of the pandemic. In early 2020, Good Judgment superforecasters estimated the United States would have over 200,000 deaths from COVID-19 with 99 percent certainty, an estimate that was considered by many as excessive at the time. Warren gives show host Gene Tunny and his colleague Tim Hughes some valuable tips on how to become a superforecaster.
