Synopsis

Since its original publication, Expert Political Judgment by New York Times bestselling author Philip Tetlock has established itself as a contemporary classic in the literature on evaluating expert opinion. Tetlock first discusses arguments about whether the world is too complex for people to find the tools to understand political phenomena, let alone predict the future. He evaluates predictions from experts in different fields, comparing them to predictions by well-informed laity or those based on simple extrapolation from current trends. He goes on to analyze which styles of thinking are more successful in forecasting. Classifying thinking styles using Isaiah Berlin's prototypes of the fox and the hedgehog, Tetlock contends that the fox--the thinker who knows many little things, draws from an eclectic array of traditions, and is better able to improvise in response to changing events--is more successful in predicting the future than the hedgehog, who knows one big thing, toils devotedly within one tradition, and imposes formulaic solutions on ill-defined problems. He notes a perversely inverse relationship between the best scientific indicators of good judgement and the qualities that the media most prizes in pundits--the single-minded determination required to prevail in ideological combat. Clearly written and impeccably researched, the book fills a huge void in the literature on evaluating expert opinion. It will appeal across many academic disciplines as well as to corporations seeking to develop standards for judging expert decision-making. Now with a new preface in which Tetlock discusses the latest research in the field, the book explores what constitutes good judgment in predicting future events and looks at why experts are often wrong in their forecasts.

About this title

Review

"[This] book ... marshals powerful evidence to make [its] case.Expert Political Judgment... summarizes the results of a truly amazing research project.... The question that screams out from the data is why the world keeps believing that 'experts' exist at all."--Geoffrey Colvin, Fortune

"This book is just what one would expect from America's most influential political psychologist: Intelligent, important, and closely argued. Both science and policy are brilliantly illuminated by Tetlock's fascinating arguments."--Daniel Gilbert, Harvard University

"This book is a landmark in both content and style of argument. It is a major advance in our understanding of expert judgment in the vitally important and almost impossible task of political and strategic forecasting."--Daniel Kahneman, Princeton University, Nobel Laureate in Economics

"This is a marvelous book--fascinating and important. It provides a stimulating and often profound discussion, not only of what sort of people tend to be better predictors than others, but of what we mean by good judgment and the nature of objectivity. It examines the tensions between holding to beliefs that have served us well and responding rapidly to new information. Unusual in its breadth and reach, the subtlety and sophistication of its analysis, and the fair-mindedness of the alternative perspectives it provides, it is a must-read for all those interested in how political judgments are formed."--Robert Jervis, Columbia University

"Before anyone turns an ear to the panels of pundits, they might do well to obtain a copy of Phillip Tetlock's new book Expert Political Judgment: How Good Is It? How Can We Know? The Berkeley psychiatrist has apparently made a 20-year study of predictions by the sorts who appear as experts on TV and get quoted in newspapers and found that they are no better than the rest of us at prognostication."---Jim Coyle, Toronto Star

"[This] book . . . Marshals powerful evidence to make [its] case. Expert Political Judgment . . . Summarizes the results of a truly amazing research project. . . . The question that screams out from the data is why the world keeps believing that "experts" exist at all."---Geoffrey Colvin, Fortune

"Mr. Tetlock's analysis is about political judgment but equally relevant to economic and commercial assessments."---John Kay, Financial Times

"The definitive work on this question. . . . Tetlock systematically collected a vast number of individual forecasts about political and economic events, made by recognised experts over a period of more than 20 years. He showed that these forecasts were not very much better than making predictions by chance, and also that experts performed only slightly better than the average person who was casually informed about the subject in hand."---Gavyn Davies, Financial Times

"Tetlock uses science and policy to brilliantly explore what constitutes good judgment in predicting future events and to examine why experts are often wrong in their forecasts."--Choice

"Philip Tetlock has just produced a study which suggests we should view expertise in political forecasting--by academics or intelligence analysts, independent pundits, journalists or institutional specialists--with the same skepticism that the well-informed now apply to stockmarket forecasting. . . . It is the scientific spirit with which he tackled his project that is the most notable thing about his book, but the findings of his inquiry are important and, for both reasons, everyone seriously concerned with forecasting, political risk, strategic analysis and public policy debate would do well to read the book."---Paul Monk, Australian Financial Review
