The book is a good fun read -- so good that I missed the bus because I was so absorbed reading the first chapter and failed to proceed to cashier timely.
I enjoyed the way Dan set his creative experiment and most of the time got his points describing human predictably irrational behavior. My favorite chapter is on placebo effect --not to mention his practical joke about MIT's T-shirt that reads "Harvard: Because not everyone can get into MIT".
But somewhat I am bit wary with some of his suggested policy recommendation that gives a glimpse of paternalism. This is one example:
If you accept the premise that market forces and free market will not always regulate the market for the best, then you may find yourself among those who believe that the government (we hope a reasonable and thoughtful government) must play a larger role in regulating some market activities, even if this limits free enterprise. Yes, a free market based on supply, demand, and no friction would be the ideal if we were truly rational. Yet when we are not rational but irrational, policies should take this important factor into account.The problem: how can we find a rational government? More often than not, government is less rational than people under free market.
