Proof

“Engaging and uncondescending” —Financial Times

“Adam Kucharski's new book Proof is a life raft in a sea of fake news and misinformation.”—Jacob Aron, New Scientist

“A wide-ranging study on separating facts from fiction, truth from lies, and evidence from presumptions.” —Kirkus

"Kucharski explains why getting at the truth of just about anything is incredibly hard. There's fascinating technical detail here, and a moral: the more we appreciate how hard proof is to come by, the better we can bridge the widening gulf between experts and skeptics."—Simon Ings, New Scientist

"Adam Kucharski has a knack of making complex problems sound simple - and exciting. A book that made me smile and feel clever."—Peter Frankopan, author of The Silk Roads

"A vivid, intelligent and wide-ranging book about how we know what we know. Adam Kucharski is a brilliant and entertaining guide."—Tim Harford, author of How To Make The World Add Up

“Adam Kucharski is that rarest of beasts: a true mathematical expert who can also write beautiful accessible, human prose. Proof is a profound and utterly absorbing exploration of the limits and power of proof and truth, both in mathematics, logic, and the quest for certainty that we find ourselves on, whether we’re running the country of trying to decide on what to do with a medical test result. Kucharski elegantly explores how proof is not just a mathematical concept but a vital tool in decision-making, justice, and survival—it’s brilliant.”—Chris van Tulleken, author of Ultra-Processed People

"In an increasingly complex world, where we're beset by information, misinformation, and endlessly required to make decisions about it all, Kucharski shines a brilliant and clarifying light through the muddle. Proof is a puzzle-solver's delight; the essential guide we need to make sense of what and who to trust, and the risks therein."—Gaia Vince, author of Nomad Century
