信号与噪声 | The Signal and the Noise by Nate Silver

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, 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.文章源自：力哥爱英语（ienglish521.com）力哥爱英语-https://ienglish521.com/344.html

在信息爆炸的大数据时代，随着我们的生活节奏变得越来越快，我们所要做出的预测的速度和数量都在不断增加。一个不容忽视的事实是，现实世界中的很多预测都失败了，由此付出了巨大的社会代价。“9.11”恐怖袭击事件、2008年金融危机、卡特里娜飓风、2011年日本大地震、禽流感肆虐，这些“黑天鹅”事件的发生在很大程度上应归咎于糟糕的预测，也就是说预测者们被众多信息中的噪声干扰，而忽视了其中真正的信号。文章源自：力哥爱英语（ienglish521.com）力哥爱英语-https://ienglish521.com/344.html
