Présentation de l'éditeur
Behavioral economist and New York Times bestselling author Dan Ariely offers a much-needed take on the irrational decisions that led to our current economic crisis.
In his uniquely charming and engaging style, Dan Ariely again examines our poor decision-making processes now on a broader canvas than ever before. Taking into account recent economic events, Ariely tackles one of the biggest crises of our times: the financial meltdown and sub-prime mortgage crisis of 2008 2009, and the irrational decisions that led us there. As Ariely explains, relying on standard economic theory alone might, in fact, be dangerous. The mistakes that we make are not random but irrational, and they can aggregate in the market with devastating results.
In this revised and expanded edition of PREDICTABLY IRRATIONAL, Ariely brings a much-needed dose of sophisticated psychology to the realm of public policy. In addition to reflecting on material covered in previous chapters and responding to the thought-provoking comments of his readers, he also answers pertinent questions like:
What caused individuals to take on mortgages that were too large?
What caused bankers to lose sight of the economy?
Why didn t we plan better for the possibility of bad times?
What do we need to do to get over these difficult times?
Is there a psychological fallout from not understanding what s going on in the markets?
Is it possible that a central and global market can increase irrational behavior?
Should we use the assumptions of rational economics as building blocks for setting up policies and designing our institutions?
Blending everyday experience with groundbreaking analysis and new research into today s economic climate, Ariely explains how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. The mistakes we make are systematic and predictable and in light of our current crisis, their consequences have never been more clear. This revised and expanded edition of PREDITABLY IRRATIONAL will change the way we interact with the world from the small decisions we make in our own lives, to the individual and collective choices that shape our global economy.

Instructif et agréable à lire, mais un peu superficiel,

Ce commentaire fait référence à cette édition : Predictably Irrational: The Hidden Forces That Shape Our Decisions (Relié)
Ce livre décrit une série d'expériences qui remettent en question les présupposés économiques habituels : homo oeconomicus, maximisateur d'utilité, parfaitement informé, etc. Dan Ariely met en évidence des effets étonnants :- un placebo cher peut être plus efficace qu'un placebo bon marché - une première impression (lecture des 10 commandements, ou des derniers chiffres du N° de Sécu) peut influencer durablement nos préférences par la suite - nous sommes particulièrement sensibles aux options ou aux produits gratuits, ainsi qu'aux produits dont les caractéristiques sont facilement comparables Cependant, au long du livre, un même défaut revient régulièrement. L'auteur affirme explicitement "le choix rationnel aurait été ceci..."; puis il montre que le comportement des individus diffère de ce choix; et par conséquent il suggère des mesures correctrices. Par exemple, les gens ont tendance à ne pas respecter certaines "bonnes résolutions" : épargner, arrêter de fumer, manger moins gras. D'où l'intérêt de mettre en place une épargne automatique sur le bulletin de salaire, l'interdiction de fumer dans les lieux publics, l'interdiction des acides gras trans, etc. Le problème est que dire "voici ce qui serait rationnel" est un jugement de valeur très subjectif. Epargner c'est bien, mais consommer a ses avantages aussi; fumer c'est "cool"; et les frites, c'est bon! Dan Ariely émet des jugements de valeur un peu rapidement sur certains sujets. D'où une tendance à tirer des conclusions un peu hâtives alors qu'on aurait aimé une réflexion plus approfondie. Hormis cet aspect un peu gênant, le livre apporte des informations qui peuvent intéresser le marketing, où la perception de la qualité, la comparaison, le prix, etc. sont importants.

A fun introduction to behavioral economics,

Ce commentaire fait référence à cette édition : Predictably Irrational, Revised Intl (Broché)
Many decisions that we make in our daily lives seem quite irrational when analyzed dispassionately and coolly in terms of whether those decisions make any economic sense or are they beneficial to us in some other way. And yet, those irrational decisions are not completely random, but there is some reason to their madness. The part of psychology that deals with this "irrationality" in marketplace is referred to as behavioral economics, and this research field has had a great impact on our understanding of how markets work and has been the major intellectual and empirical driving force away from the idealized rational agents of classical economic theory.Behavioral economics is also the main subject of this eminently readable and entertaining book. In it the author, Dan Ariely, takes the reader on a tour of various ingenious and insightful psychological experiments that shed some light on the way we make economic decisions. The sorts of experiments described - from drinking various beers at restaurant, selling and buying tickets for a favorite sports team, to cheating in various situations when money or products are at stake - are all very relevant to everyday life. Ariely is also a very engaging writer and the book has a very strong personal feel. However, this overly personal approach can get to be a bit distracting at times. It would have been helpful if the author used examples from other researchers in the field or at least tried to show how his own research fits within some larger picture or framework. As it is, the reader almost gets the impression that Ariely has single-handedly come up with the ideas and concepts that are presented in this book. Another problem that I have with this book is that it doesn't seem to have a well defined focus, other than the "irrationality" itself. Too many concepts from psychology (priming, placebo, peer pressure, etc.) are conflated and made to seem to be just manifestations of single overarching "irrational" behavior. I would have also liked if the author tried to provide more explanation for why we do act in this seemingly irrational way. A brief description of evolutionary forces that shaped our thinking would have been useful. Many of these "irrational" behaviors certainly must have had some purpose; otherwise we would have become extinct long time ago. Overall, this is a very well written and entertaining introduction to behavioral economics. It will make you look at your everyday microeconomic decisions in a whole new light.

excellent ouvrage pour mieux comprendre pourquoi lorsqu'on souhaite economiser on ne peut resister a un achat compulsif, ou pourquoi un objet l'on possede a plus de valeur a nos yeux que le meme au regard d'autres personne, bref pourquoi sommes nous tellement irrationnel lorsqu'on pourrait se croire la plus rationnelle des personnes, le livre est bien ecrit et est une synthese de bon niveau accessible a tous avec de nombreux exemple, bien amenes, des etudes... bref maintenant je comprends mieux pourquoi je fais des choses qui n'ont parfois pas de sens, je continue, mais je sais pourquoi...
