Comment prenons-nous nos décisions ? Qu'est-ce qui guide nos préférences et nos jugements ? Quand faut-il faire confiance à notre intuition ? Tels sont les fils rouges de cet ouvrage, dans lequel Daniel Kahneman nous emmène à la rencontre étonnante des deux «personnages» qui se partagent notre esprit.Le «Système 1» est rapide, intuitif et émotionnel ; le «Système 2» est lent, réfléchi et logique. Via de multiples expériences auxquelles le lecteur est invité à s'essayer lui-même, Daniel Kahneman expose les ravages des partis pris et autres biais cognitifs dont nous sommes les jouets : illusion de familiarité, effet de halo, biais optimiste, effet d'ancrage...Fruit de toute une vie de recherche, Système 1 / Système 2 dessine une théorie brillante qui offre des prolongements pratiques immédiats dans la vie quotidienne et professionnelle.
From the multi-million copy bestselling author of Thinking Fast and Slow Daniel Kahneman, the co-author of the million-copy bestseller Nudge Cass Sunstein, and the eminent professor and writer on strategic thinking Oliver Sibony, a new book about how to make better decisions.
We make thousands of decisions every day, from minute choices we don''t even know we''re making up to great, agonising deliberations. But when every decision we make is life-changing, the way we reach them matters. And for every decision, there is noise.
This book teaches us how to understand all the extraneous factors that impact and bias our decision-making - and how to combat them and improve our thinking. Filled with new science, fascinating case studies and revealing practical examples, the skills this book teaches can be readily used by private or public institutions, by schools, hospitals, businesses, judges and in our everyday lives.
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.
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.
