So fascinating. Behavioral economics is a fascinating field, and you're bound to read something in this book that will make you stop and reflect on your own behavior, and something that will help you understand the irrational things other people do.

I enjoyed this read. There were some generalizations that I did not agree with.

Dan Ariely describes different experiments in this book to show how we are very irrational and can be influenced easily by the immediate environment. Each chapter describes a certain influence/force that can affect our behavior in different situations. I wish this book was shorter. Some interesting ideas but long and repetitive sometimes. (yet I’m giving it 4 stars because I haven’t read something similar to it)

One of the interesting ideas mentioned in chapter one is about how irrational we are when decide between three choices where two of them are easily comparable. Between Paris (P), Rome (R) and another Room trip with a free breakfast (R+), you would favor Rome with the free breakfast because you would unconsciously compare it to the other Rome trip.

In another experiment from chapter two, students were asked to write the last two digits of their social security numbers on a sheet and then write whether they were willing to pay that number for some items listed in the sheet. After that students were asked to bid on those items. Students with a higher social security number bid higher.

More ideas in the book revolved around how how free cost more, the high price of ownership (over valuing objects only when we own them), how dealing with cash can make us more honest, and more. I would read more books by the same author. Definitely entertaining.

An incredible book bursting with interesting gems. Completely demolishes the economic myth of rational consumers (I'm an economics student so this is especially relevant to me). An easy and enjoyable read

As the title suggests, a true eye-opener to the absurdity of our rationale in daily decision-making.

I read the book after watching Prof. Ariely and Prof. Kariv's debate in my college. Very interesting and makes you think about the daily decisions you take.

It makes sense that this was published during the time a lot of pop science/economic books were coming out. the author performs minor experiments with college students and make broad generalizations about what they mean. None of these ideas are revolutionary.

Fascinating stuff, and has me thinking about how to bribe/trick myself for my own good.
My only complaint is that this occasionally felt like the Cliff's Notes, and I wanted the grown up version.
