It's called Predictably Irrational: The Hidden Forces That Shape Our Decisions, by Dan Ariely at MIT.
Advance praise from George Akerlof, Nobel Laureate in Economics:
“Predictably Irrational is wildly original. It shows why–much more often than we usually care to admit–humans make foolish, and sometimes disastrous, mistakes. Ariely not only gives us a great read; he also makes us much wiser.”
