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.

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.

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.

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. (http://www.ted.com/talks/dan_ariely_asks_are_we_in_control_of_our_own_decisions.html)
