Introduction

Philip E. Tetlock, a psychologist at the University of Pennsylvania, and journalist Dan Gardner published Superforecasting in 2015. It's based on the Good Judgment Project, a large forecasting tournament funded by a US intelligence research agency.

Tetlock found that a small group of 'superforecasters' consistently made more accurate predictions than others.
