About the Author
Nate Silver is a statistician and political forecaster at The New York Times. In 2012, he correctly predicted the outcome of 50 out of 50 states during the US presidential election, trumping the professional pollsters and pundits. He was named one of TIME's 100 Most Influential People in the world, and one of Rolling Stones' top Agents of Change. He lives in Brooklyn, New York.

The Nobel prize-winning physicist Niels Bohr famously said 'Prediction is very difficult, especially if it's about the future'. This pretty much sums up the first half of the book. Yes, the detail about the financial crisis, weather forecasting, earthquakes etc is mildly interesting, but in relation to prediction, you will be wading through a lot of noise to extract the signal ('human nature makes us over-confident predictors', 'without either good theory or good empirical data, you may as well just guess','the most confident pundits are usually the worst' etc).
The substance of the book comes in twenty pages in the middle, where Silver introduces Bayesian logic (I learnt in maths classes at school when I was fourteen so it wasn't new to me, and it doesn't need 200 pages of build up). The best section is where Silver contrasts Bayesian logic to Fisherian logic. Fisher created the maths that is used almost universally in medical and social science research to prove the efficacy of a treatment or theory. Silver explains how flawed this maths is - which is presumably why two thirds of the positive findings claimed in medical journals cannot be replicated. This is pretty heady stuff.
Silver claims that the second half of the book is about how to make predictions better. It is mostly more examples of failure, this time in chess, investment, climate and terrorism, with a few asides that might be considered signals ('testing is good', 'groups/markets tend to make better predictions than individuals').Read more ›
My two main criticisms for non Americna readers is that it is quite US centric (I don't care about baseball, and the general moneyball story is impossible to avoid) and the main philosophical stuff (which was most useful and ineresting to me) makes up a small portion of the book, the majority with various examples where he makes the same arguments with interview of different people that are somewhat non-questioning.
He gives some useful examples throughout the book, covering meteorology, earthquakes, transmision of viruses, but it still feels as if it could have been cut. The stuff on Bayes is interetsing but really skates over the issue of how you come up with a Bayesian prior when you can't iteratively improve them because you do not have many data points. Given the time he spends looking at the financial crisis, this is a flaw as it reduces the "wow, Bayes is really useful" impact when it cannot offer that much resolution to the problem of predicting economic and financial crises, the key predictive failure he cites.
Even so, as a way of getting people to think a bit more deeply about what it is to make a prediction and how to know if it was well constructed, and how to integrate concepts of epistemology, it is a useful introductory book.

I think Silver brings up some very interesting material - however it's because he's introducing stuff like Bayesian theory (on a very superficial level). Read morePublished 1 month ago by Modern Primate
Loved this book. Reducing the topics to simple maths and analysis told the story in a way that a high school student could follow. Read morePublished 2 months ago by A. Sykes
