Query: Thought provoking book, challenging conventional wisdom and conclusions

The books seems to have become a must-read, and for good reason. I didn't agree with every conclusion that the authors come to by applying economic and social science to varying social topics; but I did agree with the process and analysis. This kind of analysis, purveyed by thinkers such as these authors and writers such as Malcolm Gladwell, challenges "conventional wisdom," and often the status quo by looking deeper at issues and at underlying social influences. The book is written in plain language and is very readable (one plane flight or less). You will come away having learned something important.
