(p. B1) I think Philip Tetlock’s “Superforecasting: The Art and Science of Prediction,” co-written with the journalist Dan Gardner, is the most important book on decision making since Daniel Kahneman’s “Thinking, Fast and Slow.” (I helped write and edit the Kahneman book but receive no royalties from it.) Prof. Kahneman agrees. “It’s a manual to systematic thinking in the real world,” he told me. “This book shows that under the right conditions regular people are capable of improving their judgment enough to beat the professionals at their own game.”
The book is so powerful because Prof. Tetlock, a psychologist and professor of management at the University of Pennsylvania’s Wharton School, has a remarkable trove of data. He has just concluded the first stage of what he calls the Good Judgment Project, which pitted some 20,000 amateur forecasters against some of the most knowledgeable experts in the world.
The amateurs won–hands down.
. . .
(p. B7) The most careful, curious, open-minded, persistent and self-critical–as measured by a battery of psychological tests–did the best.
. . .
Most experts–like most people–“are too quick to make up their minds and too slow to change them,” he says. And experts are paid not just to be right, but to sound right: cocksure even when the evidence is sparse or ambiguous.
