New York Times Book Review

Why do our headaches persist after we take a one-cent aspirin but disappear when we take a fifty-cent aspirin? Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?

When it comes to making decisions in our lives, we think we're making smart, rational choices. But are we?

In this newly revised and expanded edition of the groundbreaking New York Times bestseller, Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. From drinking coffee to losing weight, from buying a car to choosing a romantic partner, we consistently overpay, underestimate, and procrastinate. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable—making us predictably irrational.

Dan Ariely is the James B. Duke Professor of Psychology and Behavioral Economics at Duke University, and is the founder of the Center for Advanced Hindsight. His work has been featured in theNew York Times,Wall Street Journal,Washington Post,Boston Globe, and elsewhere. He lives in North Carolina with his family.

Rated 5 out of 5 by from Fascinating reading, incredible insights into how we think I found this book to be fascinating. Even though this is a scholarly work, it is very readable and easily understood. The finding of Mr. Ariely and his associates are well illustrated by an assortment of simple experiments that were conducted at several well respected Universities. Before I started reading, I felt that I made quite rational decisions and that I was not unduly swayed by advertising and other outside influences. I now suspect that this might not be true. I was surprised to find how much we are all influenced by our surrounding and those around us. Whether it affects our decision of how long a magazine subscription to select, whether I need a medication or will a placebo suffice, is a free item really free, or even if we have ordered what we truly desire in a restaurant or did we make our choice so it will be different that everyone else at the table. I was further surprised to find that even our level of honesty can be influenced by a variety of circumstances. Mr. Ariely does not leave us without hope. He does assure the reader that he can make rational decisions. I would highly recommend this book to any who are a student of understanding human nature. Now I am wondering how I can use my new found knowledge to get my children to do what I want them to do without them realizing how much I have influenced their decision.

Rated 4 out of 5 by from An interesting look at how our brains work This is definitely a book that will make you question all of your gut reactions. The examples he brings up are easy to translate into your own life and see how the pratfalls of your own brain affect your decision making. It is definitely a book I recommend.

Rated 5 out of 5 by from Excellently written and thoroughly enjoyable Contrary to what you might think, humans are not rational actors. Dan Ariely investigates many facets of our lives in which people behave in predictable ways, but not in the ways they *should* rationally behave. Once you are aware of ways in which we behave irrationally, you can start to make better decisions.

Rated 5 out of 5 by from Good & Interesting Read Very well-written book with a great collection of experiments performed by Ariely himself. A good read regardless of whether you're looking to use its information for marketing applications or just for some insight into how humans work and perceive their surroundings.

Rated 4 out of 5 by from An entertaining & informative read Thoroughly enjoyed "Predictably Irrational". Marketing professionals might know a lot of the tricks researched in this easy read. Some of the subjects were eye-openers to me. It just shows that nothing happens in a vacuum and somebody, somewhere has figured out a long, long time ago how you'll respond.

Rated 4 out of 5 by from Essential for Marketers I found this book very thought provoking. Ariely provides simple insight into how decisions are made an influenced. His findings are based on research and his writing is entertaining. It is an essential read for any marketing or product manager.

Rated 5 out of 5 by from It makes you think... Ariely has many smart ideas, definitely it's a good read and quite entertaining too. I particularly liked Chapter 4, The Cost of Social Norms (why we are happy to do things, but not when we are paid to do them) about the fine balance between social and market norms that many companies seem to have forgotten when dealing with their employees. I hope executives at various companies who constantly cut benefits and increase work hours, monetizing everything, read it and learn something from it. If you want a preview, search at TED talks, he gives some presentations there with ideas that appear in the book. (

Editorial Reviews

“Freakonomics held that people respond to incentives, perhaps in undesirable ways, but always rationally. Dan Ariely shows you how people are deeply irrational, and predictably so.”
