The provocative follow-up to the New York Times bestseller Predictably Irrational
- Why can large bonuses make CEOs less productive?
- How can confusing directions actually help us?
- Why is revenge so important to us?
- Why is there such a big difference between what we think will make us happy and what really makes us happy?
In his groundbreaking book Predictably Irrational, social scientist Dan Ariely revealed the multiple biases that lead us into making unwise decisions. Now, in The Upside of Irrationality, he exposes the surprising negative and positive effects irrationality can have on our lives. Focusing on our behaviors at work and in relationships, he offers new insights and eye-opening truths about what really motivates us on the job, how one unwise action can become a long-term habit, how we learn to love the ones we're with, and more.
Drawing on the same experimental methods that made Predictably Irrational one of the most talked-about bestsellers of the past few years, Ariely uses data from his own original and entertaining experiments to draw arresting conclusions about how—and why—we behave the way we do. From our office attitudes, to our romantic relationships, to our search for purpose in life, Ariely explains how to break through our negative patterns of thought and behavior to make better decisions. The Upside of Irrationality will change the way we see ourselves at work and at home—and cast our irrational behaviors in a more nuanced light.

About the author

Officially, I am the James B. Duke Professor of Psychology & Behavioral Economics at Duke University.
I founded the Center for Advanced Hindsight, wrote a few books, took part in a few media project and startups.
I co-created of the film documentary (Dis)Honesty: The Truth About Lies, and I wrote three-time New York Times bestsellers: Predictably Irrational, The Upside of irrationality, and The Honest Truth About Dishonesty. I also wrote a few books that did not make it to the New York Times bestsellers list: Irrationally Yours, Payoff, Amazing Decisions and Dollars and Sense.
My new book, MISBELIEF: WHAT MAKES RATIONAL PEOPLE BELIEVE IRRATIONAL THINGS began with my own experience being the target of conspiracy theories, but quickly became about a phenomenon that affects all of us. I will use the term misbelief to describe the phenomenon we’re exploring. Misbelief is a distorted lens through which people begin to view the world, reason about the world, and then describe the world to others.
I derive a lot of satisfaction from seeing my work take shape in the real life and I take part in a few companies / startups. Among them are: Lemonade, Shapa, Irrational Capital, BEWorks, Epilog, Timeful, and Irrational Labs.
I am also part of a team that is working on an NBC TV series that is loosely based on my life and will premiere on NBC in the fall of 2023. The show is called “The Irrational” and officially it is based on my first book, Predictably Irrational.

- Reviewed in the United States on July 28, 2010Format: HardcoverVerified PurchaseThe author used a very easy-going manner in discussing some important ideas that we often take for granted and on which many of us are often wrong.
One of the first concepts he discusses is the idea of the HEDONISTIC TREADMILL or the idea of keeping up with the Jones philosophy which in large part resulted in our present economic mess. As part of this concept the author discusses HEDONISTIC ADAPTATION in which people perform certain activities to either maximize their pleasure or reduce their pain. Intuitively we might think that if we were trying to study and our partner were running the vacuum, we would want that person to complete part of the cleaning,then quit for a while, do a little more and quit again, but that is not what the experimental results showed. We tend to build up an adaptation to an unpleasurable activity as it progresses and if it is stopped we lose that adaptation and must work harder to build up the adaptation a succeeding time[s] , so that in this case if would be better if the person continued with the unpleasurable activity until completed, another example of that might be completing your income tax return in one sitting rather than spreading it out over several days. The corollary to that is that it is better to break up a pleasurable activity into smaller portions to savor its effects for a longer period of time. An example of that might be sex; for that I can refer you to the Alan Jackson song in which the refrain goes "Nothing left to do after we done it!"
The author also discusses concepts as people with certain levels of attractiveness seek partners of approximately equal levels of attractiveness, although a caveat is made that women are more forgiving on physical levels of partners attractiveness than are men. There are still a lot more men rated a 4 trying to hook up with a female 10 than a woman who is 4 believing she is going to find the 10 male.
Another topic reviewed was can we really act rationally in a fit of anger and, if in such an angry state, how does it affect our ideas of fairness and unfairness [revenge] towards many other people not just the person we think caused us pain. These are just a few of the topics discussed out of many interesting areas.
As others have mentioned and as has the author, he was severely injured as a young soldier due to a bomb blast and suffered some permanent scarring and limited range of motion from it, yet he overcame that and turned his life into a worthwhile endeavor in spite of injuries both physical and psychological and I speak as someone who interned at a VA hospital during the Viet Nam war, so am familiar with such wounds. It is obvious from the ease with which he discusses his various topics that he is learned and intelligent which is also supported by the fact that he was a professor at MIT and now a professor at Duke. As a disclaimer, I have never met nor talked to the author, but simply liked the book and think you will too.
- Reviewed in the United States on February 23, 2018Format: KindleVerified Purchase-This is an extension of the previous book, Predictable Irrationality, but this book goes one step further and gives guidance with many different areas where we make faulty decisions because of the inherent biases that we have.
-The book is broken down into two sections, one that has more to do with business related issues and the other, with issues that are more of a personal nature. The basic format is to come up with an idea that is being questioned and then to either support that idea or negate it by some sort of experiment. For example, we consider it an automatic and not to be questioned idea that the more pay that you offer someone, the more they could be motivated. Motivation for pay, though, has a limit, and after reaching that limit, increased pay has a negative effect on performance. The rationale is that the person is so fixated on the prize, that the actual job being done suffers.
-Some of the chapters cover ideas that may be related strongly, but the ideas have some sort of twist to them, so that they truly are different. Personal relationships is something that’s of interest to everyone, and new light is shed on certain facets of relationships and dating. For example, he delves into the on line dating world and give criticisms of why it isn’t set up as it should be. The human mind works in a certain way, and relationships are sparked by spontaneity. The dryness of the descriptions of each person in dating sites, inhibit the release of that spark which causes two people to relate to each other. But it’s the detail that he goes into, and recommendations for improvement, that makes this all the more interesting.
-There is also a lot of personal experience that he reveals here, which adds to the interest, and he injects personal tales throughout the book.
-All in all, there are very good and thought provoking ideas presented that can’t all be digested with just one reading. Very good for its presentation as well. Though the ideas it presents are not what you would expect, it’s an easy read, and you’ll find yourself going through the book very quickly while highlighting at least a third of what’s written.

5.0 out of 5 stars Unentbehrlich!
Format: Mass Market PaperbackVerified PurchaseFür alle, die ein wenig mehr von der Welt (und ganz besonders den Leuten um sich) verstehen wollen. Mit harter Wissenschaft stellt Ariely klar, dass unsere Intuition gegenüber den Motiven Anderer nicht wirklich hilfreich ist. Rationales Verhalten ist offensichtlich die Ausnahme - solange man das weiß ist alles gut - jetzt könnte man es verstehen, wissen und anwenden.
- Mle Ingrid FalkowskiReviewed in the United Kingdom on May 3, 2013
5.0 out of 5 stars Interesting while easy to read
This type of book is sometimes written in a very convoluted style that make them hard to read (especially if englidh is not your mother tongue). This one while being based on research and describing very interesting topics is written in a very enjoyable way: it alternates anecdotes and research description and teaches so much about why people act one way or another and how this can be influenced.
Definitely one of the best read I had in a long time.

5.0 out of 5 stars Passionnant pour comprendre le fonctionnement irrationnel du cerveau, et savoir en tirer parti
Format: Mass Market PaperbackVerified PurchaseAviez-vous remarqué que l'être humain ne se comporte pas toujours de façon rationnelle, que ce soit dans sa vie privée ou professionnelle ? Dan Ariely démonte les mécanismes qui expliquent cette apparente absence de logique, au travers de sujets pas toujours originaux, mais finalement toujours d'actualité, comme le syndrome du « pas inventé ici », l'impact sur la performance de la rémunération au bonus ou le besoin de sens que chacun éprouve vis-à-vis de son travail.
L'un des apports les plus originaux de l'ouvrage réside dans l'étude des phénomènes d'adaptation et de résistance à des épisodes douloureux. L'expérience personnelle de l'auteur dans ce domaine est en effet remarquable... et donne lieu parfois à des descriptions difficiles à soutenir : brûlé au troisième degré sur 70 % du corps suite à un accident dans sa jeunesse, atteint par ailleurs d'hépatite C, il a eu tout le loisir de vérifier comment l'esprit humain réagit dans ce type de circonstances. Les conclusions qu'il en tire s'appliquent, bien entendu, à des situations moins extrêmes, et constituent une aide utile pour que notre inévitable absence de rationalité soit pour nous, non un handicap, mais une aide dans la poursuite du bonheur.

Format: Mass Market PaperbackVerified PurchaseA little biased review by a fan - he shares another valuable insight here. I found a better way to manage my die-hard irrationality and no more negative thought about it.
