The Art of Uncertainty How to Navigate Chance Ignorance Risk and Luck

The Art of Uncertainty: How to Navigate Chance, Ignorance, Risk and Luck is statistician David Spiegelhalter’s guide to thinking clearly about what we don’t know. Drawing on decades of work in risk and probability, he shows how uncertainty is a “conscious awareness of ignorance” and how we can put numbers on it, update our beliefs, and make better choices in the face of incomplete information. The book introduces core ideas in probability and Bayesian thinking using vivid real‑world examples—from medical advice, pandemic and climate forecasts, and football outcomes to everyday luck and coincidences—while stressing the limits of models and the need for humility about our own ignorance.
