NEW YORK TIMES BESTSELLER
Nate Silver built an innovative system for predicting baseball performance, predicted the 2008 election within a hair's breadth, and became a national sensation as a bloggerall by the time he was thirty. The New York Times now publishes FiveThirtyEight.com, where Silver is one of the nation's most influential political forecasters.
Drawing on his own groundbreaking work, Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the "prediction paradox": The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.
In keeping with his own aim to seek truth from data, Silver visits the most successful forecasters in a range of areas, from hurricanes to baseball, from the poker table to the stock market, from Capitol Hill to the NBA. He explains and evaluates how these forecasters think and what bonds they share. What lies behind their success? Are they goodor just lucky? What patterns have they unraveled? And are their forecasts really right? He explores unanticipated commonalities and exposes unexpected juxtapositions. And sometimes, it is not so much how good a prediction is in an absolute sense that matters but how good it is relative to the competition. In other cases, prediction is still a very rudimentaryand dangerousscience.
Silver observes that the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.
With everything from the health of the global economy to our ability to fight terrorism dependent on the quality of our predictions, Nate Silver's insights are an essential read.
"Yogi Berra was right: 'forecasting is hard, especially about the future.' In this important book, Nate Silver explains why the performance of experts varies from prescient to useless and why we must plan for the unexpected. Must reading for anyone who cares about what might happen next."
Richard Thaler, co-author of Nudge
"Making predictions in the era of 'big data' is not what you might imagine. Nate Silver's refreshing and original book provides unpredictably illuminating insights differentiating objective and subjective realities in forecasting our future. He reminds us that the human element is still essential in predicting advances in science, technology and even politics… if we were only wise enough to learn from our mistakes."
Governor Jon Huntsman
"Here's a prediction: after you read The Signal and the Noise, you'll have much more insight into why some models work welland also why many don't. You'll learn to pay more attention to weather forecasts for the coming weekand none at all for weather forecasts beyond that. Nate Silver takes a complex, difficult subject and makes it fun, interesting, and relevant."
Peter Orszag, former director of the Office of Management and Budget
"Projection, prediction, assumption, trepidation, anticipation, expectation, estimation… we wouldn't have 80 words like this in the English language if it wasn't central to our lives. We tend not to take prediction seriously because, on some level, we know that we don't know. Silver shows us how this inevitable part of life goes awry when projected on a grand scale into the murky worlds of politics, science and economics. Dancing through chess, sports, snowstorms, global warming and the McLaughlin Group, he makes a serious and systematic effort to show us how to clean the noise off the signal."
