The Polythink Syndrome


Book Description

Why do presidents and their advisors often make sub-optimal decisions on military intervention, escalation, de-escalation, and termination of conflicts? The leading concept of group dynamics, groupthink, offers one explanation: policy-making groups make sub-optimal decisions due to their desire for conformity and uniformity over dissent, leading to a failure to consider other relevant possibilities. But presidential advisory groups are often fragmented and divisive. This book therefore scrutinizes polythink, a group decision-making dynamic whereby different members in a decision-making unit espouse a plurality of opinions and divergent policy prescriptions, resulting in a disjointed decision-making process or even decision paralysis. The book analyzes eleven national security decisions, including the national security policy designed prior to the terrorist attacks of 9/11, the decisions to enter into and withdraw from Afghanistan and Iraq, the 2007 "surge" decision, the crisis over the Iranian nuclear program, the UN Security Council decision on the Syrian Civil War, the faltering Kerry Peace Process in the Middle East, and the U.S. decision on military operations against ISIS. Based on the analysis of these case studies, the authors address implications of the polythink phenomenon, including prescriptions for avoiding and/or overcoming it, and develop strategies and tools for what they call Productive Polythink. The authors also show the applicability of polythink to business, industry, and everyday decisions.




Expert Political Judgment


Book Description

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.




Superforecasting


Book Description

NEW YORK TIMES BESTSELLER • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE ECONOMIST “The most important book on decision making since Daniel Kahneman's Thinking, Fast and Slow.”—Jason Zweig, The Wall Street Journal Everyone would benefit from seeing further into the future, whether buying stocks, crafting policy, launching a new product, or simply planning the week’s meals. Unfortunately, people tend to be terrible forecasters. As Wharton professor Philip Tetlock showed in a landmark 2005 study, even experts’ predictions are only slightly better than chance. However, an important and underreported conclusion of that study was that some experts do have real foresight, and Tetlock has spent the past decade trying to figure out why. What makes some people so good? And can this talent be taught? In Superforecasting, Tetlock and coauthor Dan Gardner offer a masterwork on prediction, drawing on decades of research and the results of a massive, government-funded forecasting tournament. The Good Judgment Project involves tens of thousands of ordinary people—including a Brooklyn filmmaker, a retired pipe installer, and a former ballroom dancer—who set out to forecast global events. Some of the volunteers have turned out to be astonishingly good. They’ve beaten other benchmarks, competitors, and prediction markets. They’ve even beaten the collective judgment of intelligence analysts with access to classified information. They are "superforecasters." In this groundbreaking and accessible book, Tetlock and Gardner show us how we can learn from this elite group. Weaving together stories of forecasting successes (the raid on Osama bin Laden’s compound) and failures (the Bay of Pigs) and interviews with a range of high-level decision makers, from David Petraeus to Robert Rubin, they show that good forecasting doesn’t require powerful computers or arcane methods. It involves gathering evidence from a variety of sources, thinking probabilistically, working in teams, keeping score, and being willing to admit error and change course. Superforecasting offers the first demonstrably effective way to improve our ability to predict the future—whether in business, finance, politics, international affairs, or daily life—and is destined to become a modern classic.







Economic Forecasting


Book Description

A comprehensive and integrated approach to economic forecasting problems Economic forecasting involves choosing simple yet robust models to best approximate highly complex and evolving data-generating processes. This poses unique challenges for researchers in a host of practical forecasting situations, from forecasting budget deficits and assessing financial risk to predicting inflation and stock market returns. Economic Forecasting presents a comprehensive, unified approach to assessing the costs and benefits of different methods currently available to forecasters. This text approaches forecasting problems from the perspective of decision theory and estimation, and demonstrates the profound implications of this approach for how we understand variable selection, estimation, and combination methods for forecasting models, and how we evaluate the resulting forecasts. Both Bayesian and non-Bayesian methods are covered in depth, as are a range of cutting-edge techniques for producing point, interval, and density forecasts. The book features detailed presentations and empirical examples of a range of forecasting methods and shows how to generate forecasts in the presence of large-dimensional sets of predictor variables. The authors pay special attention to how estimation error, model uncertainty, and model instability affect forecasting performance. Presents a comprehensive and integrated approach to assessing the strengths and weaknesses of different forecasting methods Approaches forecasting from a decision theoretic and estimation perspective Covers Bayesian modeling, including methods for generating density forecasts Discusses model selection methods as well as forecast combinations Covers a large range of nonlinear prediction models, including regime switching models, threshold autoregressions, and models with time-varying volatility Features numerous empirical examples Examines the latest advances in forecast evaluation Essential for practitioners and students alike




The Next 100 Years


Book Description

“Conventional analysis suffers from a profound failure of imagination. It imagines passing clouds to be permanent and is blind to powerful, long-term shifts taking place in full view of the world.” —George Friedman In his long-awaited and provocative new book, George Friedman turns his eye on the future—offering a lucid, highly readable forecast of the changes we can expect around the world during the twenty-first century. He explains where and why future wars will erupt (and how they will be fought), which nations will gain and lose economic and political power, and how new technologies and cultural trends will alter the way we live in the new century. The Next 100 Years draws on a fascinating exploration of history and geopolitical patterns dating back hundreds of years. Friedman shows that we are now, for the first time in half a millennium, at the dawn of a new era—with changes in store, including: • The U.S.-Jihadist war will conclude—replaced by a second full-blown cold war with Russia. • China will undergo a major extended internal crisis, and Mexico will emerge as an important world power. • A new global war will unfold toward the middle of the century between the United States and an unexpected coalition from Eastern Europe, Eurasia, and the Far East; but armies will be much smaller and wars will be less deadly. • Technology will focus on space—both for major military uses and for a dramatic new energy resource that will have radical environmental implications. • The United States will experience a Golden Age in the second half of the century. Written with the keen insight and thoughtful analysis that has made George Friedman a renowned expert in geopolitics and forecasting, The Next 100 Years presents a fascinating picture of what lies ahead.

The Hedgehog and the Fox


Book Description

"The fox knows many things, but the hedgehog knows one big thing." This ancient Greek aphorism, preserved in a fragment from the poet Archilochus, describes the central thesis of Isaiah Berlin's masterly essay on Leo Tolstoy and the philosophy of history, the subject of the epilogue to War and Peace. Although there have been many interpretations of the adage, Berlin uses it to mark a fundamental distinction between human beings who are fascinated by the infinite variety of things and those who relate everything to a central, all-embracing system. Applied to Tolstoy, the saying illuminates a paradox that helps explain his philosophy of history: Tolstoy was a fox, but believed in being a hedgehog. One of Berlin's most celebrated works, this extraordinary essay offers profound insights about Tolstoy, historical understanding, and human psychology. This new edition features a revised text that supplants all previous versions, English translations of the many passages in foreign languages, a new foreword in which Berlin biographer Michael Ignatieff explains the enduring appeal of Berlin's essay, and a new appendix that provides rich context, including excerpts from reviews and Berlin's letters, as well as a startling new interpretation of Archilochus's epigram.




Blindside


Book Description

A host of catastrophes, natural and otherwise, as well as some pleasant surprises—like the sudden end of the cold war without a shot being fired—have caught governments and societies unprepared many times in recent decades. September 11 is only the most obvious recent example among many unforeseen events that have changed, even redefined our lives. We have every reason to expect more such events in future. Several kinds of unanticipated scenarios—particularly those of low probability and high impact—have the potential to escalate into systemic crises. Even positive surprises can be major policy challenges. Anticipating and managing low-probability events is a critically important challenge to contemporary policymakers, who increasingly recognize that they lack the analytical tools to do so. Developing such tools is the focus of this insightful and perceptive volume, edited by renowned author Francis Fukuyama and sponsored by The American Interest magazine. Bl indside is organized into four main sections. "Thinking about Strategic Surprise" addresses the psychological and institutional obstacles that prevent leaders from planning for low-probability tragedies and allocating the necessary resources to deal with them. The following two sections pinpoint the failures—institutional as well as personal—that allowed key historical events to take leaders by surprise, and examine the philosophies and methodologies of forecasting. In "Pollyana vs. Cassandra," for example, James Kurth and Gregg Easterbrook debate the future state of the world going forward. Mitchell Waldrop explores why technology forecasting is so poor and why that is likely to remain the case. In the book's final section, "What Could Be," internationally renowned authorities discuss low probability, high-impact contingencies in their area of expertise. For example, Scott Barrett looks at emerging infectious diseases, while Gal Luft and Anne Korin discuss energy security. How can we avoid




The Timeline of Presidential Elections


Book Description

In presidential elections, do voters cast their ballots for the candidates whose platform and positions best match their own? Or is the race for president of the United States come down largely to who runs the most effective campaign? It’s a question those who study elections have been considering for years with no clear resolution. In The Timeline of Presidential Elections, Robert S. Erikson and Christopher Wlezien reveal for the first time how both factors come into play. Erikson and Wlezien have amassed data from close to two thousand national polls covering every presidential election from 1952 to 2008, allowing them to see how outcomes take shape over the course of an election year. Polls from the beginning of the year, they show, have virtually no predictive power. By mid-April, when the candidates have been identified and matched in pollsters’ trial heats, preferences have come into focus—and predicted the winner in eleven of the fifteen elections. But a similar process of forming favorites takes place in the last six months, during which voters’ intentions change only gradually, with particular events—including presidential debates—rarely resulting in dramatic change. Ultimately, Erikson and Wlezien show that it is through campaigns that voters are made aware of—or not made aware of—fundamental factors like candidates’ policy positions that determine which ticket will get their votes. In other words, fundamentals matter, but only because of campaigns. Timely and compelling, this book will force us to rethink our assumptions about presidential elections.
