Every day, we turn to experts to help us navigate an uncertain world. We listen to political pundits on television, read economic forecasts in newspapers, and seek guidance from foreign policy specialists. We assume that people with decades of experience, advanced degrees, and access to privileged information must have some special insight into what will happen next. Philip Tetlock spent twenty years testing this assumption. What he found is deeply unsettling. Beginning in the mid-1980s, Tetlock and his research team collected more than 28,000 predictions from 284 experts in politics, economics, and international affairs. These were not amateurs or casual commentators. They were professors, government officials, journalists, and think tank analysts, many with distinguished careers and impressive credentials. The researchers asked them to make specific predictions about real-world events: Would the Soviet Union collapse? Would there be a recession? Would a particular election produce a peaceful transfer of power? Then Tetlock waited. And scored. And waited some more. The results were sobering. When asked to predict outcomes within their areas of expertise, these professionals performed only slightly better than random guessing. They were routinely outperformed by simple extrapolation algorithms that assumed current trends would continue. And they were decisively beaten by even basic statistical models. Perhaps most troubling was the finding that expertise itself seemed to offer little protection against error. A distinguished professor with thirty years of experience was no more accurate than a well-informed graduate student. Access to classified information did not improve forecasting. A PhD in political science did not help. Even fame and reputation were useless as predictors of accuracy. If anything, the most famous experts tended to be the least reliable forecasters, in part because their confidence made them attractive to media outlets seeking definitive answers. But Tetlock's research did not end with this discouraging conclusion. Buried within the data was a more hopeful finding: some experts did perform better than others. The difference was not in what they believed but in how they thought. Drawing on Isaiah Berlin's famous distinction between the hedgehog…
