内容简介 · · · · · ·

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 blogger—all 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, Silve...

(展开全部)

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 good—or 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 rudimentary—and dangerous—science.

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.

原文摘录 · · · · · · ( 全部 )

预测时，我们需要在好奇和怀疑之间寻求平衡。这两者是可以相互协调和融合的。我们越是渴望检验自己的假设，就越愿意承认我们关于世界的知识存在很多不确定，越愿意承认不可能做出完美的预测，越不会陷入失败的恐慌中，也会有更多的自由让思维驰骋。对自己不了解的事物作进一步的了解，我们也许就能做出更多准确的预测。 (查看原文)

预测的艺术

在我们日常的生活中，我们时时都是进行预测。然而大多数个人的预测都是带有个人的偏见和立场的，这种预测的精度甚至不如一群乌合之众预测的平均值。人类最大的预测市场，就是股市和体育，所有的人都希望在这样的市场一试身手，体现自己少有的天赋。不过大多数都会铩羽而归，... (展开)

流于肤浅

读了几页就感觉到了作者的思维方式和角度非同凡响，越读越觉得有兴趣。但是越读，越觉得食之无味。涉及到的方面特别多，但是没有一块是深入讲如何鉴别信号与噪声的。都是一些流于肤浅的方面。个人建议作者可以抓住其中的一方面和一个领域，进行深入剖析和讲解即可成为一本特好... (展开)

Nate Silver的霸气大作

在奥巴马成功连任总统之前，美国几乎所有重要的刊物和评论员都认为，奥巴马和罗姆尼在伯仲之间，各有五成的胜算。此时，《纽约时报》FiveThirtyEight博客的作家Nate Silver却给出了不同的答案：Silver一直坚持奥巴马的胜算在七成左右。 Silver的这一论点让其他评论员对其群起... (展开)
