According to the author of Predictably Irrational, we live simultaneous in the world of social norms and the world of market norms. Social norms are the exchanges and requests we make as part of personal connections. Market norms are the dollar-defined exchanges of dollars, wages, rents, prices. Here's where it gets interesting:

Yes, humans see credit differently than cash. Ariely uses that premise to show how easy it is for companies such as Enron to steal vast sums without feeling the same as a mugger taking money from an old lady's purse, despite the end result being the same.

Reading this book may not make us more rational in our behavior. The least it does is to help us identify our abilities and inabilities. In short our limitations in a given context. Gradually with the awareness of our limitations, we can be relatively more rational. Be a better judge for others, since it is relatively easy to judge others and eventually a better person ourselves.

The most important lesson I learned from Ariely is the high cost of free. The biggest example is "free shipping." Companies only offer you free shipping to convince you to spend at least the minimum amount to get it. Something to think about the next time I shop online.

"Blink" vs "Predictably Irrational"
I was in awe of Blink: The Power of Thinking without Thinking. Well, take the sensationalism out of it, add more scientific rigor, and you get "Predictably Irrational". This isn't to say that the topics handled are the same.
Dan Ariely covers a pretty wide range of topics varying from the appeal of all things free to how 'good' and 'honest' people cheat when the cheating is just 'a little ...more
While it is comforting to know that so many decisions are made on from irrational bases, it is discomforting to be made quite so aware of it. No, I take that back: it is quite reassuring to know that while the principles of logic have their place, people are influenced by other factors.
Professor Ariely explains some of the factors that influence our decisionmaking: from the influence of emotions to the sometimes agonising choice between ...more
