The Peculiar Blindness of Experts

The Atlantic

...In 2005, [Philip] Tetlock published his results, and they caught the attention of the Intelligence Advanced Research Projects Activity, or IARPA, a government organization that supports research on the U.S. intelligence community’s most difficult challenges. In 2011, IARPA launched a four-year prediction tournament in which five researcher-led teams competed. Each team could recruit, train, and experiment however it saw fit. Predictions were due at 9 a.m. every day. The questions were hard: Will a European Union member withdraw by a target date? Will the Nikkei close above 9,500? Tetlock, along with his wife and collaborator, the psychologist Barbara Mellers, ran a team named the Good Judgment Project.
