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 soexceedingly 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. Lire la suite Fermer

Dès qu'il y a jugement, il y a bruit. Quand deux médecins posent des diagnostics différents pour le même patient, quand deux juges attribuent des peines plus ou moins lourdes pour le même crime, quand deux responsables de ressources humaines prennent des décisions opposées à propos d'un candidat à un poste, nous sommes face au bruit.
Daniel Kahneman, Olivier Sibony et Cass R. Sunstein montrent dans ce livre que le bruit exerce des effets nocifs dans de nombreux domaines : médecine, justice, protection de l'enfance, prévision économique, recrutement, police scientifique, stratégie d'entreprise... Pourtant, le bruit reste méconnu. Il est la face cachée de l'erreur de jugement. Noise nous propose des solutions simples et immédiatement opérationnelles pour réduire le bruit dans nos jugements et prendre de meilleures décisions. Lire la suite Fermer

La nouvelle édition du livre fondateur sur le nudge : le livre de référence sur l'économie comportementale.


Richard Thaler, spécialiste de l'économie comportementale, prix Nobel d'économie, et Cass Sunstein, l'un des plus grands juristes américains, nous invitent à expérimenter le nudge. Le nudge, c'est le monde des incitations douces, à l'image des parents éléphants qui donnent un léger coup de trompe à leurs petits pour leur permettre d'aller dans la bonne direction.
Ce livre, à l'origine du phénomène Nudge, s'appuie sur les recherches comportementales les plus poussées pour prendre de meilleures décisions. Il engage le lecteur à changer fondamentalement sa façon de penser, tout en préservant sa liberté de choix.
Mise à jour, enrichie et augmentée, cette édition analyse les effets du nudge et expose notamment les critiques formulées à son encontre. Elle intègre également de nouveaux thèmes majeurs : la Covid-19, la transparence de l'information, le sludge... Enfin, elle traite avec un regard neuf des questions telles que le changement climatique, le don d'organe, les finances personnelles...

Cette approche originale de l'économie comportementale nous donne un gentil coup de pouce (« Nudge » en anglais) pour aborder facilement des questions sérieuses. Lire la suite Fermer

A much-needed defense of liberalism--what it is, why it is under threat, and why we need it more than ever--from one of our most important political thinkers today.

More than at any time since World War II, liberalism is under pressure, even siege. On the right, some have given up on liberalism. They hold it responsible for the collapse of the family and traditional values, rampant criminality, disrespect for authority, and widespread immorality. On the left, some are turning their backs on liberalism. They think that it lacks the resources to handle the problems posed by entrenched inequalities, racism, sexism, corporate power, and environmental degradation. But those opposed to liberalism do not depict it accurately; they offer a caricature, and they neglect its history.

How information can make us happy or miserable, and why we sometimes avoid it and sometimes seek it out. How much information is too much? Do we need to know how many calories are in the giant vat of popcorn that we bought on our way into the movie theater? Do we want to know if we are genetically predisposed to a certain disease? Can we do anything useful with next week''s weather forecast for Paris if we are not in Paris? In Too Much Information , Cass Sunstein examines the effects of information on our lives. Policymakers emphasize "the right to know," but Sunstein takes a different perspective, arguing that the focus should be on human well-being and what information contributes to it. Government should require companies, employers, hospitals, and others to disclose information not because of a general "right to know" but when the information in question would significantly improve people''s lives. Sunstein argues that the information on warnings and mandatory labels is often confusing or irrelevant, yielding no benefit. He finds that people avoid information if they think it will make them sad (and seek information they think will make them happy). Our information avoidance and information seeking is notably heterogeneous--some of us do want to know the popcorn calorie count, others do not. Of course, says Sunstein, we are better off with stop signs, warnings on prescriptions drugs, and reminders about payment due dates. But sometimes less is more. What we need is more clarity about what information is actually doing or achieving. Lire la suite Fermer

The different ways that social change happens, from unleashing to nudging to social cascades."Sunstein''s book is illuminating because it puts norms at the center of how we think about change."--David Brooks, The New York TimesHow does social change happen? When do social movements take off? Sexual harassment was once something that women had to endure; now a movement has risen up against it. White nationalist sentiments, on the other hand, were largely kept out of mainstream discourse; now there is no shortage of media outlets for them. In this book, with the help of behavioral economics, psychology, and other fields, Cass Sunstein casts a bright new light on how change happens.Sunstein focuses on the crucial role of social norms--and on their frequent collapse. When norms lead people to silence themselves, even an unpopular status quo can persist. Then one day, someone challenges the norm--a child who exclaims that the emperor has no clothes; a woman who says "me too." Sometimes suppressed outrage is unleashed, and long-standing practices fall. Sometimes change is more gradual, as "nudges" help produce new and different decisions--apps that count calories; texted reminders of deadlines; automatic enrollment in green energy or pension plans. Sunstein explores what kinds of nudges are effective and shows why nudges sometimes give way to bans and mandates. Finally, he considers social divisions, social cascades, and "partyism," when identification with a political party creates a strong bias against all members of an opposing party--which can both fuel and block social change.
