The Signal and the Noise Introduction Summary
"The Signal and the Noise" is a non-fiction book written by Nate Silver that talks about predictions based on probability; particularly focusing on the outcomes of real-world predictions and why they did or did not fail. Published in 2012, this book is a commentary on the world of probability made by an ex-statistician. Silver begins this work by effectively emphasizing the relevance of his points by supporting his argument with data applicable to a wide audience. In the introduction, Silver begins by talking about the printing press and its role as the first invention to mass produce information, and the inherent consequences of such. “We face danger whenever information growth outpaces our own understanding of it” (7). To support this claim, Silver uses a graph which illustrates how the value of books in Europe dropped quite dramatically as the number of books grew due to the printing press. The theme here is that there is a discernible difference between information and useful information. The more information we have, the better we can make predictions about our futures. However, if that information is getting taken in at a higher rate than we can process, it gets harder and harder to separate what's necessary from what isn't. This is essentially the idea behind the title "The Signal and the Noise". At the end of the introduction, Silver explains how the signal is the truth and that the noise is often what distracts us from the truth (17). Silver also outlines the difference between predictions and forecasts. Predictions are inferences about the future based on existing data, while forecasts are inferences about the future based on uncertainty. With this definition of predictions in mind, one can see the correlation between his two main topics; the importance of useful information and methods for making accurate predictions.
