Life is shot through with uncertainty, but in this fascinating, witty and perspective-shifting book, Tom Chivers shows why this needn't condemn us to powerlessness and panic. I finished Everything Is Predictable not only better informed about a captivating branch of mathematics, but with an invigorating sense of greater purchase on the world -- OLIVER BURKEMAN One thing that is perfectly predictable is that Tom Chivers writes terrific books. This one is no exception: it's witty, lively and best of all, extremely nerdy. I learned a lot and so will you -- TIM HARFORD A remarkable book by a remarkable writer about a remarkable theorem. The statistical chance of it not changing how you see the world forever is zero -- WILL STORR From assessing the effectiveness of treatments, to the way consciousness works and the way we make decisions, Tom Chivers makes a compelling case that Bayes' Theorem is the one formula that everyone should understand -- ANANYO BHATTACHARYA From an eighteenth-century cleric to the workings of the brain, Chivers explores the impact of Bayes' theorem; the mathematical basis for learning under uncertainty. After neatly summarising the history of probability and statistics, he handles challenging and controversial Bayesian approach to scientific evidence, induction, decision-making, statistical modelling, prediction, and human perception and reasoning. All with his customary light touch, and full of quotes and vivid stories. A filling but very tasty book -- DAVID SPIEGELHALTER
