From the best-selling author of Thinking, Fast and Slow, the co-author of Nudge, and the author of You Are About to Make a Terrible Mistake! comes Noise, a revolutionary exploration of why people make bad judgments, and how to control both noise and cognitive bias.
Imagine that two doctors in the same city give different diagnoses to identical patients - or that two judges in the same courthouse give markedly different sentences to people who have committed the same crime. Suppose that different interviewers at the same firm make different decisions about indistinguishable job applicants - or that when a company is handling customer complaints, the resolution depends on who happens to answer the phone. Now imagine that the same doctor, the same judge, the same interviewer, or the same customer service agent makes different decisions depending on whether it is morning or afternoon, or Monday rather than Wednesday. These are examples of noise: variability in judgments that should be identical.
In Noise, Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein show the detrimental effects of noise in many fields, including medicine, law, economic forecasting, forensic science, bail, child protection, strategy, performance reviews, and personnel selection. Wherever there is judgment, there is noise. Yet, most of the time, individuals and organizations alike are unaware of it. They neglect noise. With a few simple remedies, people can reduce both noise and bias, and so make far better decisions.
Packed with original ideas, and offering the same kinds of research-based insights that made Thinking, Fast and Slow and Nudge groundbreaking New York Times best sellers, Noise explains how and why humans are so susceptible to noise in judgment - and what we can do about it.

Title: A five-star book that may not be for you
Review: Noise: A Flaw in Human Judgment is an excellent book. But if youâre a reader of business books, Noise may not be the book for you. Most business books get right to practical applications of the author/s key ideas. This book does not. Itâs an academic book with business applications. The big question is whether this book is worth your time as a business reader.The first two thirds of the book set up the later chapters. The later chapters cover many specific techniques you can use to reduce noise and improve judgement and prediction. Don't jump right to them, though. Â The early part of the book lays the necessary groundwork for you to understand why the techniques work. Later Iâll identify chapters with particular value for business readers.Noise is about two things that affect our judgment. Bias is systematic deviation. Noise is random scatter. We need to understand both to improve judgment. Alas, most of the time noise hardly gets any consideration while bias is the star of the show. The authors wrote this book to âredress the balance.âThey say that the key theme of the book is: âwherever there is judgment there is noise --and more of it than you think.âThe book is divided into six parts. Part one is about the difference between noise and bias. Part two is about human judgment. Part three is about predictive judgment. Part four describes the psychological causes of noise. Part five explores several practical issues. This is the part that would be of greatest interest to most business readers. Part six wraps up the book with techniques for measuring and overcoming noise.Thereâs a lot of actionable value for businesspeople, but as I said earlier, you need to read the first two thirds of the book to get to it. Here are some things that may make the book worth your time.This is an excellent overview of structured decision processes and why they often improve judgment. There are also specific chapters you may find interesting and helpful.Chapter 23 is âDefining the Scale in Performance Ratings.â Some research indicates that performance only has a 20 percent impact on the final performance evaluation. This chapter includes techniques you can use to reduce both bias and noise and make your evaluations fairer and more consistent.Chapter 24 is âStructure in Hiring.â Hiring almost always involves at least one interview. And interviewers make subjective judgments about the person they interview. We know that humans arenât very good at sussing out whether a particular person will succeed or fail on the job. We know that different interviewers often have wildly varying assessments of the same candidate. This chapter will give you some tools for improving the results of your interviews.Chapter 25 is âThe Mediating Assessments Protocol.â This has special value for you if you are a maker of deals and subject to what has been called âdeal heat.â The mediating assessment protocol is a tool for overcoming deal heat and making better decisions.Chapter 28 is âRules or Standards?â I never thought about the difference between these two until I read this chapter. You learn how rules and standards affect the amount of judgment in particular situations.In a NutshellNoise is an excellent book about improving our judgment by reducing scattered results (noise) and reducing inconsistencies in the decision process. The first two thirds of the book establish the definitions and principles for dealing with noise. The final third of the book has several chapters with practical applications of the principles.

Title: An Important Book, Just Not Thinking Fast and Slow
Review: Daniel Kahneman always stresses the importance of priming: loosely, that we naturally allow the most recent experience to affect our judgment.With that in mind, many readers come to Noise hoping for something of like importance to Thinking Fast and Slow. That work summarized decades of Nobel Prize winning research that showed how human beings use heuristics to reach decisions that run counter to what a statistical, or at least well thought out approach, would make.Noise is not such a book. Most of the research are summaries of the work of other scientists, there is a lot of explanatory material that many readers will find redundant with their education and both wordiness and repeated material that should have been avoided.Nevertheless, it is an important book. Noise shows in the real world the importance of the statisticianâs distinction between bias and variance. A model can be inaccurate not only by being biased and consistent but also by providing widely varying answers around a true value.While most people in research or the business world emphasize reducing bias, Kahneman and his co-authors emphasize the importance of reducing noise. Prison sentences that vary widely from different judges, contradictory diagnoses from different physicians and different evaluations of workplace performance are just some of the areas that could benefit from noise reduction.After showing its importance, the authors then analyze noise into its different components: level bias where different scales are used; pattern noise resulting from hidden factors such as personality or experience; and occasion noise which is the influence that moods and other idiosyncratic factors have that cause judgment to fluctuate (technically a subtype of pattern noise).The authors then give a serious treatment of ways to reduce noise in different settings: personal methods, such as training people to continually update their views with contrary perspectives; and collective approaches such as how to best leverage the expertise of a team charged with an important business decision.Again, much of the material can be found in other books and Noise is not the equivalent of Kahneman and Tverskyâs years of original research into a previously unexplored topic. But if you expect to read a useful and important book that enables better decision making you will not be disappointed. Highly recommended.

Review: Everything is really so noisy yet we hardly notice (hear) it, we have become so attuned to it like it doesnât matter but it does.This book clearly describes it all and will help the reader recognize that silent noise that we so easily miss. You will be more attentive to whats being done to you and what you equally do to others unknowingly.

Title:
Review: The book focuses on errors in human decision processes that impact our judgment. The book can be considered an extension of the famous Thinking Fast and Slow moving beyond individual and exploring impacts of those errors on organisations and societies.The authors distinguish between bias - systematic deviations between people, and noise, which is a random scatter. To understand errors in judgment, we must understand both bias and noise. Often, noise is a more important problem for the organisations and is therefore the main focus of the book aiming at improving our understanding of noise and proposing some ways to mitigate it.

Review: Gran secuela de Thinking, Fast and Slow. Añade una capa de complejidad a los sesgos psicológicos que entran en juego al momento de la toma de decisiones: el contexto y los factores externos que también influyen en el individuo.

Review: La edición esta muy sencilla. Muy al estilo de libros modernos de no muy alta calidad.Apenas llevo la mitad del libro y no esperen que sea tan relevante como pensar rápido y despacio.Los puntos presentados son muy interesantes pero tampoco son de tal impacto como el libro anterior. No es una desepcion, tiene buenos puntos pero no es la gran maravilla.En general buena compra. Pero no tan increÃble como el libro anterior del Kanheman.
