Predictably Irrational

Why do our headaches persist after taking a one-cent aspirin but disappear when we take a 50-cent aspirin?Why does recalling the Ten Commandments reduce our tendency to lie, even when we couldn't possibly be caught?Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?Why do we go back for second helpings at the unlimited buffet, even when our stomachs are already full?And how did we ever start spending $4....

Reviews Predictably Irrational

  • Petra X
    “I asked them why when they persecute men, for religion or colour it was seen by the world as oppression and when they persecute women, it was dismissed as tradition.” Emer Martin This book is generally brilliant if you ignore the misogyny. It is a book written by a man about a man's world for men. The "Our' in the title does not include half the world. The misogny, the putting down of fat women, ugly ones, old ones in this often otherwise in...

    It is important that you move this one up your list of books that you have to read. This is a particularly great book. My dear friend Graham recommended I read this book. He has recommended four books to me – and the only one I couldn’t finish was “My Cousin, My Gastroenterologist: A novel” by Mark Leyler – but he did recommend, “The Tetherballs of Bougainville” also by Leyler and that is still one of the most remarkable books I’v...

    Written in the tried-and-tested and bestselling tradition of the Malcolm Gladwell books and the Frekonomics clones, Dan Ariely's book too is an entertaining and counter-intuitive look at the world around us. While I am getting more and more inured to this way of analysis of behavioral economics and physchology, these kinds of books are still hard to resist - that is because they do, no matter if they have now become an industry doling out similia...

    This book was somewhat entertaining, but I can't really recommend it. The author does experiments with college students and beer, and extrapolates this into a world view. Most of his applications are anecdotal.Here's an example on p. 215: "Iran is another example of a nation stricken by distrust. An Iranian student at MIT told me that business there lacks a platform of trust. Because of this, no one pays in advance, no one offers credit, and no o...

    Honestly all the business books that talk about psychological research or behavioral economics talk about the same things. I haven't even read Thinking Fast and Slow by Daniel Kahneman but all these books literally rehash it again and again so I probably wouldn't even get anything out of reading it now. That said this one's much better written than most of the other books I've read and so if you haven't read anything else about behavioral economi...

    All classic economic theories are based on the assumption that consumers behave rationally, despite a considerable body of evidence to the contrary. It is only in the last 25 years that economists have begun to investigate the irrational side of consumer behavior. This field of investigation, which started with the pioneering work of Tversky and Kahneman, is usually referred to as behavioral economics. Dan Ariely's book, "Predictably Irrational"...

    Yet another book I'm recommending to Goodreads staff. I will write up a long review when it's done, but I think this is worth chewing on:According to the author of Predictably Irrational, we live simultaneous in the world of social norms and the world of market norms. Social norms are the exchanges and requests we make as part of personal connections. Market norms are the dollar-defined exchanges of dollars, wages, rents, prices. Here's where it ...

    As a social psychologist, I have been trained to scoff at all "behavioral economists" because they often claim to have recently discovered that individuals do not always behave "rationally". Furthermore, they seem to brilliantly deduce that the only way to accurately predict how humans actually behave is to test behavior/decision making empirically. Of course, social psychologists have been doing this for over half a century without much public f...
  • Caroline
    This is a wonderfully interesting and amusing book. Every time I had a few spare minutes, I would leap back into it with gusto. Some of the things I read I had already seen elsewhere - but much was new to me. The author is described as a behavioural economist.....and I think this book would interest anyone who is interested in psychology.This book is tops. There are enough reviews here singing its praises already. I shall simply end with some not...

    Ch1: Explores the ability of a decoy option to determine outcomes.(The economist subscription, travel to rome or france w/free breakfast)Ch2:Our first experience becomes our anchor point that future instances are pegged to and rebound towards like a rubber band.Anchor points are hard to change, but new anchor points can be created wholecloth by giving people a new experience (starbucks vs. dunkin donuts)Ch3:The power of FREE! to disguise the actu...

    توي يه مبحث از يه جايي به بعد محتواي كتابا تقريبا تكراري مي شن. با اين حال خوش مزه بود. ريويو هم اگه زمان اجازه بده به زودي.
  • Darin
    Ariely is a good writer whose book catches onto the _Freakonomics_ craze by taking a look at times when people make different decisions that typical "laissez faire" economic theories would expect. His book is a fairly easy read and does include some surprising results through social-science experimentation. However, the text is not without its flaws. For instance, some of the breathlessly-reported "surprising" results aren't all that surprising o...
  • Ahmad Davari
    همه ی ما به طرز پیش بینی پذیری نابخردانه عمل می کنیم. این کتاب به موضوعات جالبی پرداخته است. موضوعات روزمره و دم دستی که عموم ما آدم ها در آن دچار اشتباه می شویم. خواندنش را به شدت توصیه می کنم.
  • Kathrynn
    If I had to describe Predictably Irrational using two words they would be "thought provoking." The author is a professor who was injured in an explosion in Israel. He suffered severe burns and 5 years of therapy. He used this "down time" to ponder the why's and how come's of life. Using many experiments he (and others) tested the moral aptitude and other aspects of human behavior. Each chapter has several experiments that pertain to a topic. Chap...

    Here are just a few tidbit's I've learned:-If you're ever going to a bar, trying to score a little bit of lovin', bring a friend who looks very similar to you - only a little uglier. That way you'll look like the ideal candidate, not just compared to your friend but to everyone else there.-People are more likely to steal things once removed from cash than cash - ie. the Enron crew who stole millions of dollars from the retirement pensions of litt...
    Predictably Irrational is an entertaining and enlightening read. The most important lesson I learned from Ariely is the high cost of free. The biggest example is "free shipping." Companies only offer you free shipping to convince you to spend at least the minimum amount to get it. Something to think about the next time I shop online.Many of Ariely's lessons on psychology were already explained to me in previous books, but that isn't a strike agai...

    What an interesting book. It complemented my last reading ~ Thinking Fast and Slow by Kahneman ~ in some ways. The examples in the book suggests that `The Neo Cortex` is such a funny dude that tricks us into thinking that we are making logical decision, that we are rational beings. In the meanwhile the other machinery that actually makes and executes the decision is pulling our strings. As stated in the book, we are a true Jeckll and Hyde dilemma...

    It's only about the middle of the year, but I think Dan Ariely's Predictably Irrational is a shoe-in for my favorite non-fiction book of 2008. When I was studying psychology one of my favorite topics was judgment and decision-making, which dealt in large part with the kinks in the human mind that could lead us to irrational behavior and decisions. Why are you likely to pay more for something if you are shown a large number completely unrelated to...

    reads like an extended, slightly dumbed down USA today article.

    Un libro de sicología/sociología que destaca sobre la gran mayoría, porque el autor HACE EXPERIMENTOS para comprobar sus teorías. Son experimentos fáciles, cotidianos y bastante divertidos, sobre todo cuando uno ve lo irracional que podemos ser las personas y cómo nos da por pisar el palito, jajaja.No leía este tipo de estudios desde la universidad. Me trajo buenos recuerdos.Una cita divertida:"Suponga que está usted en un bar, disfrutand...

    Whether you are into behavioral economics or not, whether there are better books than "Predictably Irrational" out there or not, it is still a must read I feel. For one, it is less economics and more behavioral psychology (this would be considered good or bad depending on your expectations though). Two, about 50% of the experiments that the Author carries out and talks about at length in the book are fascinating and eye-opening. The rest of them,...

    There’s a generalization that people make that really gets me. It’s the idea that people naturally prefer or practice competition over collaboration or cooperation. Usually this is said as a way to dismiss addressing inequalities in America and to explain why capitalism is the only choice. Socialism or any hybrid economic system is doomed. Doomed! There are several reasons the acceptance of individual competition over striving for the group...

    علم اقتصاد انسان رو موجودی آگاه می دونه که عقلانی رفتار می کنه و به دنبال حداکثر بهره در موقعیت های مختلف می گرده. اما این کتاب نشون می ده که آدمیزاد در خیلی از موارد بی منطق رفتار می کنه. اما این بی منطق بودن تا حد زیادی قابل پیش بینیه و می شه برای جلوگ...

    Another book that looks at human behavior, and how we don't behave logically even when we are sure we do. This follows the same well-worn path of Sway, Freakonomics, and Blink, and after having read those, there wasn't a lot new here.Yes, humans see credit differently than cash. Ariely uses that premise to show how easy it is for companies such as Enron to steal vast sums without feeling the same as a mugger taking money from an old lady's purse,...
  • huzeyfe
    Yine müthiş bir kitap. Aslında daha önceki kitaplar kadar tam bana hitap etmiyor. Daha çok tüketici ve satıcı iliskileri üzerinde dönen bölümler var ama kitabı da sırf buna indirgemek haksızlık olabilir. En çok etkilendiğim bölüm karar verme mekanizmamızda izafiyet kavramının önemi ve çıpa kavramını açıkladığı yer diyebilirim. Mesela:"Ne kadar çok şeyimiz olursa, o kadar çok şey isteriz. Ve tek çare izafiyet ...

    If the brain is predictably irrational, then the books which warn us we aren’t the rational creatures we hope are also predictable. I don’t think there was a single circumstance in Ariely’s book I wasn’t already aware of from one experiment or another, one summary or another. That said, Predictably Irrational is well written and easy to digest; there’s no technobabble, and everything is presented in a very readable and readily understan...

    Yazarın kitabın girişindeki kısacık önsözde anlattığı biyografisi de en az kitapta ileri sürülen fikirler kadar ilginç. İnsan davranışlarındaki irrasyonaliteyi senelerdir finans piyasalarını izleyen biri olarak biliyor ve daha ileri giderek bu irrasyonalitenin oluşturduğu düzenli yapıları inceliyorum. Bu kitapta ileri sürülen ve deneylerle desteklenen görüşlerin bir kısmı yeni değil; sosyal psikoloji ile uğraşanl...

    כל מיני סיפורים ומחקרים על כלכלה התנהגותית ואיך החשיבה שלנו לא רציונלית.הספר פחות ממוקד מספר ההמשך לא רציונלי אבל לא נורא וגם קצת מייאש אבל עדיין מעניין מאוד ואולי יכול לעזור בהחלטות בחיים.
