Noise: The New Book from the Authors of ‘Thinking, Fast and Slow’ and ‘Nudge’

THE INTERNATIONAL BESTSELLER ‘A monumental, gripping book … Outstanding’ SUNDAY TIMES ‘Noise may be the most important book I've read in more than a decade. A genuinely new idea so exceedingly important you will immediately put it into practice. A masterpiece’ Angela Duckworth, author of Grit ‘An absolutely brilliant investigation of a massive societal problem that has been hiding in plain sight’ Steven Levitt, co-author of Freakonomics From the world-leaders in strategic thinking and the multi-million copy bestselling authors of Thinking Fast and Slow and Nudge, the next big book to change the way you think. We like to think we make decisions based on good reasoning – and that our doctors, judges, politicians, economic forecasters and employers do too. In this groundbreaking book, three world-leading behavioural scientists come together to assess the last great fault in our collective decision-making: noise. We all make bad judgements more than we think. Noise shows us what we can do to make better ones. Noise: A Flaw in Human Judgment by Daniel Kahneman explores the concept of inconsistency in human decision-making, building on research from his earlier works. The book examines how variability in judgments—termed 'noise'—affects outcomes across fields like medicine, law, and business. Kahneman and co-authors Olivier Sibony and Cass R. Sunstein analyze sources of this inconsistency, including cognitive biases and systemic flaws, and propose methods to reduce noise in professional and personal decisions. The work centers on empirical evidence and practical frameworks to improve judgment accuracy, emphasizing the high stakes of unchecked variability in high-stakes environments.
