The diversity of topics treated by applied statistics by the author in this book is quite broad: earthquakes, baseball, congressional and presidential politics, stock markets, and even terrorism. Its not overly complex, rather informally written, but clear. The insights gained are explained, as are the limitations of statistical decision or prediction making. Also well covered is the problems of models (overfitting of the data), and difficulties in getting enough data, and good data. It even earned a special place in my heart for its commitment to Bayesianism. (I should add that Richard Jeffrey's little book on Bayesianism "Subjective Probability: the real thing" is available as a free pdf e-book at fitelson dot org.)

A very good discussion of statistics and probability. This is a fairly technical book, which is a bit dense in part even though it is written for a general audience. Silver talks about the math behind predictions from politics to finance to weather to natural disasters, and explains why some things are really hard to predict accurately.

This is a worthwhile book for those who would like a basis for skepticism about the information we get from news programs, although it could have been more concise. The most valuable chapter deals with the Bayes approach to making and updating predictions. If you can multiply, divide, add and subtract, you can use this formula as he directs. There is an error in the graphs on page 357 in that the grey areas represent "individual investors".

Nate Silver, who clashed with TV Republican political pundits on TV prior to the 2012 presidential elections, predicted correctly all 50 states in 2012, demonstrating that their opinions were political bluster rather than intelligent dialogue. In 2008, Silver correctly predicted 49 of 50 states, giving him a 0.990 batting average, whereas political pundits such as Peggy Noonan and Joe Scarborough were sent back to the minor leagues. In this book, Silver discusses how probability and statistics can be used to study such phenomena as earthquakes, climate change, poker, chess, terrorism, and financial bubbles, among other phenomena. This would be a good book for economists, business majors (including sports management), mathematicians, engineers and scientists (including political science). In fact, maybe this should be required reading for such majors. I was hoping Nate would describe some of his political predicting methods, but maybe he is saving that for his next book.

I expected the book to be about politics and was pleasantly surprised about the variety to topics covered. An extremely interesting book which kept my attention the entired way through.

An interesting, well-written book but I found it wasn't as user-friendly as I expected. It seemed to me that a lay person couldn't grasp all the concepts Silver had stated and explained.

Having said that I have to concede that this might well be the starting point for many of us to dig deeper and try to learn the statistics and Math involved in predictions.

I liked the way Silver explained the difference between risk and uncertainty and predictions and forecasts. All in all an eminently readable book.

An excellent analysis of how we get mis-led by predictions of so called experts---like pundits and TV weathermen---and how they deceive themselves or purposely distort their forecasts to get noticed.
A must read for any academic in almost any field and anyone else who wants to see how they can get mis-led and how to question what you read/hear.
