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.

The Sunday Times bestseller ‘A monumental, gripping book … Outstanding’ Sunday Times Wherever there is human judgement, there is noise. ‘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. Imagine that two doctors in the same city give different diagnoses to identical patients – or that two judges in the same court give different sentences to people who have committed matching crimes. Now imagine that the same doctor and the same judge make different decisions depending on whether it is morning or afternoon, or Monday rather than Wednesday, or they haven’t yet had lunch. These are examples of noise: variability in judgements that should be identical. In Noise, Daniel Kahneman, Olivier Sibony and Cass R. Sunstein show how noise produces errors in many fields, including in medicine, law, public health, economic forecasting, forensic science, child protection, creative strategy, performance review and hiring. And although noise can be found wherever people are making judgements and decisions, individuals and organizations alike commonly ignore its impact, at great cost. Packed with new ideas, and drawing on the same kind of sharp analysis and breadth of case study that made Thinking, Fast and Slow and Nudge international bestsellers, Noise explains how and why humans are so susceptible to noise and bias in decision-making. We all make bad judgements more than we think. With a few simple remedies, this groundbreaking book explores what we can do to make better ones.

Surprisingly, it is also a pleasure to read' - Daniel Kahneman, author of Thinking, Fast and Slow A lively, research-based tour of nine common decision-making traps - and practical tools for avoiding them - from a professor of strategic thinking We make decisions all the time. It's so natural that we hardly stop to think about it. Yet even the smartest and most experienced among us make frequent and predictable errors. So, what makes a good decision? Should we trust our intuitions, and if so, when? How can we avoid being tripped up by cognitive biases when we are not even aware of them? You're About to Make a Terrible Mistake! offers clear and practical advice that distils the latest developments in behavioural economics and cognitive psychology into actionable tools for making clever, effective decisions in business and beyond.

Solving complex problems and selling their solutions is critical for personal and organizational success. For most of us, however, it doesn't come naturally and we haven't been taught how to do it well. Research shows a host of pitfalls trips us up when we try: We're quick to believe we understand a situation and jump to a flawed solution. We seek to confirm our hypotheses and ignore conflicting evidence. We view challenges incompletely through the frameworks we know instead of with a fresh pair of eyes. And when we communicate our recommendations, we forget our reasoning isn't obvious to our audience. How can we do it better? In Cracked It!, seasoned strategy professors and consultants Bernard Garrette, Corey Phelps and Olivier Sibony present a rigorous and practical four-step approach to overcome these pitfalls. Building on tried-and-tested (but rarely revealed) methods of top strategy consultants, research in cognitive psychology, and the latest advances in design thinking, they provide a step-by-step process and toolkit that will help readers tackle any challenging business problem. Using compelling stories and detailed case examples, the authors guide readers through each step in the process: from how to state, structure and then solve problems to how to sell the solutions. Written in an engaging style by a trio of experts with decades of experience researching, teaching and consulting on complex business problems, this book will be an indispensable manual for anyone interested in creating value by helping their organizations crack the problems that matter most.
