Abstract

ABSTRACT Tetlock's Expert Political Judgment is a creative, careful, and mostly convincing study of the predictive accuracy of political experts. My only major complaints are that Tetlock (1) understates the predictive accuracy of experts, and (2) does too little to discourage demagogues from misinterpreting his work as a vindication of the wisdom of the average citizen. Experts have much to learn from Tetlock's epistemological audit, but there is still ample evidence that, compared to laymen, experts are very good.
