We are fallible, regardless of what the traditional economists say. That's the book in a nutshell, but Ariely's experiments on the different facets of our fallibility are fascinating. Having read "Thinking, Fast and Slow" by Kahneman, I knew a great deal already about some of our issues with being completely rational. Still, Ariely's style is incredibly readable and compelling. Get this book.

Interesting discussion of various cognitive biases we're prone to, how we can react to them in a useful manner and their impact on policies (healthcare, corporate regulation, etc.). I want to read more on behavioral economics now.

This is a splendid little book by a MIT behavioral economist. The author did have a lot of fun doing his experiments in showing us how predictably irrational people are.

This book you can think of like Blink, Tipping Point, and Freakonmoics.
Some of the topics that stuck out were people's irrational infatuation with FREE, the differences in decision making for men in "aroused" and "cold" states (I want to see the grant request for that experiment!), people citing the Ten Commandments before a decision makes for a more honest decision, and finally the boundaries between social and market requests.

The way he described the experiments were a little convoluted. And I also wonder how people knowing they are part of an experiment behave differently.

Any person who doesn't understand why people can be so irrational should read this.

Listened and thoroughly enjoyed this. Kudos to the narrator for bringing the author’s content to life.

Behavioral economics is new to me, but I’d recommend the book to anyone seeking a deeper understanding of the forces that drive decision-making… particularly when those decisions don’t “make sense.”

I am an Economist graduate and Behavioral Economics is one of my favorite topics to learn and think about so no wonder I enjoyed reading this book. But I would have enjoyed it more and gave the book a higher rating if I didn't notice subtle misogyny. Anyways, the author writes in a simple and engaging way so that even the general readers can appreciate the book thoroughly.

Good... but if you're into this one, read Thinking Fast and Slow ("TF&S") instead (https://www.goodreads.com/book/show/11468377-thinking-fast-and-slow).

Predictably Irrational ("PI") covers some good stuff, but he's VERY repetitive --- reiterating and rephrasing everything 3-4x in an effort to be clear, when probably 1-2 reiterations/rephrases would be sufficient....

TF&S is more comprehensive, more concise, and better written in general. Both the author (winner of Nobel Prize in Economics) and the book itself (National Academy of Science Best Book, etc) are mega award-winners. AND, if it matters to you, the other book has double the ratings, and a better overall rating, than PI on Amazon. ;)

So, go check it out! It's one of my ultimate nonfiction faves:

Similar to Freakonomics and Malcolm Gladwell books but nothing that interesting to me.

Ariely makes some great points. Repeatedly. If you need to read about something three times in sightly different ways one after another in painful detail then this book was written for you.

Honestly there's some great information in here but it was aggravating to read. Also much of the valuable information could be found in Thinking, Fast and Slow, by Daniel Kahneman.
