SUPERFORECASTING

THE ART AND SCIENCE OF PREDICTION

A must-read field guide for the intellectually curious.

Superforecasting—predicting events that will occur in the future—is not only possible; it accounts for an entire industry. World-renowned behavioral scientist Tetlock (Expert Political Judgment: How Good Is It? How Can We Know, 2005, etc.) explains why some people are so good at it and how others can cultivate the skill.

Global forecasting is hardly limited to predicting the weather. In fact, much of it has significantly higher stakes: everything from the potential of conflict in the North China Sea to the 2016 presidential election is at play. Legions of intelligent, well-educated, and well-paid analysts digest data and attempt to make hundreds of nuanced predictions each year. Remarkably, in his seminal 20-year study, the author established that, on average, these “experts” are “roughly as accurate as a dart-throwing chimpanzee.” On the other hand, the superforecasters Tetlock has recruited are far more accurate: his team handily beat their competitors in a forecasting tournament sponsored by a U.S. government agency, providing more accurate answers than even those with access to classified files. And here’s the rub: his all-volunteer team is composed entirely of so-called ordinary people with ordinary jobs. In this captivating book, Tetlock argues that success is all about the approach: foresight is not a gift but rather a product of a particular way of thinking. Superforecasters are open-minded, careful, curious, and self-critical. They make an initial prediction and then meticulously adjust this prediction based on each new piece of related information. In each chapter, the author augments his research with compelling interviews, anecdotes, and historical context, using accessible real-world examples to frame what could otherwise be dense subject matter. His writing is so engaging and his argument so tantalizing, readers will quickly be drawn into the challenge—in the appendix, the author provides a concise training manual to do just that.

A must-read field guide for the intellectually curious.

AN INDIGENOUS PEOPLES' HISTORY OF THE UNITED STATES

A Churchill-ian view of native history—Ward, that is, not Winston—its facts filtered through a dense screen of ideology.

Custer died for your sins. And so, this book would seem to suggest, did every other native victim of colonialism.

Inducing guilt in non-native readers would seem to be the guiding idea behind Dunbar-Ortiz’s (Emerita, Ethnic Studies/California State Univ., Hayward; Blood on the Border: A Memoir of the Contra War, 2005, etc.) survey, which is hardly a new strategy. Indeed, the author says little that hasn’t been said before, but she packs a trove of ideological assumptions into nearly every page. For one thing, while “Indian” isn’t bad, since “[i]ndigenous individuals and peoples in North America on the whole do not consider ‘Indian’ a slur,” “American” is due to the fact that it’s “blatantly imperialistic.” Just so, indigenous peoples were overwhelmed by a “colonialist settler-state” (the very language broadly applied to Israelis vis-à-vis the Palestinians today) and then “displaced to fragmented reservations and economically decimated”—after, that is, having been forced to live in “concentration camps.” Were he around today, Vine Deloria Jr., the always-indignant champion of bias-puncturing in defense of native history, would disavow such tidily packaged, ready-made, reflexive language. As it is, the readers who are likely to come to this book—undergraduates, mostly, in survey courses—probably won’t question Dunbar-Ortiz’s inaccurate assertion that the military phrase “in country” derives from the military phrase “Indian country” or her insistence that all Spanish people in the New World were “gold-obsessed.” Furthermore, most readers won’t likely know that some Ancestral Pueblo (for whom Dunbar-Ortiz uses the long-abandoned term “Anasazi”) sites show evidence of cannibalism and torture, which in turn points to the inconvenient fact that North America wasn’t entirely an Eden before the arrival of Europe.

A Churchill-ian view of native history—Ward, that is, not Winston—its facts filtered through a dense screen of ideology.

GOOD ECONOMICS FOR HARD TIMES

Occasionally wonky but overall a good case for how the dismal science can make the world less—well, dismal.

“Quality of life means more than just consumption”: Two MIT economists urge that a smarter, more politically aware economics be brought to bear on social issues.

It’s no secret, write Banerjee and Duflo (co-authors: Poor Economics: A Radical Rethinking of the Way To Fight Global Poverty, 2011), that “we seem to have fallen on hard times.” Immigration, trade, inequality, and taxation problems present themselves daily, and they seem to be intractable. Economics can be put to use in figuring out these big-issue questions. Data can be adduced, for example, to answer the question of whether immigration tends to suppress wages. The answer: “There is no evidence low-skilled migration to rich countries drives wage and employment down for the natives.” In fact, it opens up opportunities for those natives by freeing them to look for better work. The problem becomes thornier when it comes to the matter of free trade; as the authors observe, “left-behind people live in left-behind places,” which explains why regional poverty descended on Appalachia when so many manufacturing jobs left for China in the age of globalism, leaving behind not just left-behind people but also people ripe for exploitation by nationalist politicians. The authors add, interestingly, that the same thing occurred in parts of Germany, Spain, and Norway that fell victim to the “China shock.” In what they call a “slightly technical aside,” they build a case for addressing trade issues not with trade wars but with consumption taxes: “It makes no sense to ask agricultural workers to lose their jobs just so steelworkers can keep theirs, which is what tariffs accomplish.” Policymakers might want to consider such counsel, especially when it is coupled with the observation that free trade benefits workers in poor countries but punishes workers in rich ones.

Occasionally wonky but overall a good case for how the dismal science can make the world less—well, dismal.
