Predictably Irrational: The Hidden Forces That Shape Our Decisions
Predictably Irrational The Hidden Forces That Shape Our Decisions
Author: Dan Ariely
  • 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?...  more »
  • 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 $4.15 on a cup of coffee when, just a few years ago, we used to pay less than a dollar?
When it comes to making decisions in our lives, we think we're in control. We think we're making smart, rational choices. But are we? In a series of illuminating, often surprising experiments, MIT behavioral economist Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. Blending everyday experience with groundbreaking research, Ariely explains how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. Not only do we make astonishingly simple mistakes every day, but we make the same types of mistakes, Ariely discovers. We consistently overpay, underestimate, and procrastinate. We fail to understand the profound effects of our emotions on what we want, and we overvalue what we already own. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable?making us predictably irrational. From drinking coffee to losing weight, from buying a car to choosing a romantic partner, Ariely explains how to break through these systematic patterns of thought to make better decisions. Predictably Irrational will change the way we interact with the world?one small decision at a time.

This book is very similar to The Tipping Point and Freakanomics - psychology and behavioral finance presented through fascinating examples in everyday life. An easy read - anecdotes, short stories as opposed to heavy science, textbook, or theory. I liked it better and found it more practical than the two books above.

Packed with "aha!" moments, this book should be required reading if you are a business owner, manager of volunteers, marketer, psychologist, or economist.

The exposition is full of entertaining social experiments the author (and company) have performed on the student body at MIT and others, substantiating the suprising premise of the book: that standard economic theory (which presupposes that we will consider the costs vs. benefits and make choices in our best interest) does not apply to almost any actual person. Instead, the first exposure we have to an item that links it to a value--however specious--will remain imprinted upon us and all future decisions will be based on comparisons with that initial value imprint. We overvalue what we already have, overreact to the idea of "free," and allow our expectations to cloud our experiences. We react much differently when arroused. We have issues with procrastination and self-control. And we make poor choices in order to keep our future options open.

Easy to understand style. In fact, there's no heavy intellectual lifting here; the text is written at about a second grade level (presumably because the author teaches at MIT).

Great book. Lots of thought provoking examples of how we think and act about social or market situations.
