That we cannot predict the future with any certainty is not all that shocking a revelation. Nevertheless, Ottawa Citizen columnist Dan Gardner provides an engaging tour through the recent history, science, psychology, and economics of prediction in this Malcolm Gladwellesque primer, explaining why the metaphorical reading of tea leaves remains such a popular pastime.
The core of Gardner’s account comes courtesy of the research of Philip Tetlock, a psychologist at the University of California. In a nutshell, Tetlock determined that “experts” in any given field were just slightly better at making predictions than a dart-throwing chimp. In addition, the more certain an expert was of a predicted outcome, and the bigger their media profile, the less accurate the prediction was likely to be.
Looking at the results of a variety of psychology experiments and some of the more spectacular flame-outs from recent years (population doomster Paul Ehrlich is given a particularly rough ride), Gardner examines Tetlock’s paradoxical findings and shows why being forearmed doesn’t protect us much against those seeking to forewarn us. Topics covered include why and to what extent the future must always be uncertain, why smart people make dumb predictions (and how they rationalize their mistakes), and why we are so easily conned by glib “hedgehogs” (experts who are certain of one big thing) and less impressed by thoughtful “foxes” (experts comfortable with their doubts and limitations).
The book is a fast and informative read, which helps hide the fact that Gardner’s ultimate point – that we need to cultivate skepticism and engage in cost-benefit analyses based on the probabilities of future outcomes – is rather banal. All of us know the future is uncertain, so most of what passes for prediction in the media – from market forecasts to political punditry to picking the winner of the Super Bowl – is just a form of harmless entertainment. Still, Gardner gives us a fascinating look inside this silly aspect of human nature.

Future Babble,

This review is from: Future Babble: Why Expert Predictions Fail - and Why We Believe Them Anyway (Paperback)
A thoughtful book which puts the many predictions we are faced with daily into a dubious light. Well researched and well written. This book should change one's take on media spin.

Future Babble,

This review is from: Future Babble: Why Expert Predictions Fail - and Why We Believe Them Anyway (Hardcover)
As for the author's book on risk, this book is clear, easy to read and shows why the expert predictions that we see every night on the news, should be taken with a grain of salt. Likewise the grand statements by other public figures are also likely to be based in some measure on defective information that is the result of no one taking the time to logically apply reasoning. This book should be mandatory reading for every journalist, politician and public "expert".

The disease of certainty,
This review is from: Future Babble: Why Expert Predictions Fail - and Why We Believe Them Anyway (Hardcover)
This should be required reading for everyone, experts included, who think they are qualified to predict the future. This book will act like a cold shower for those people. For the rest of us it is a fascinating examination of the disease of certainty. I now save newspaper headlines that make sweeping predictions (Climate Armageddon's-a-comin'). If I may be so bold as to make a prediction: in a few years time we will look at those headlines and shake our heads that we could have been so certain and so wrong.
