Groupthink Book

This is fantastic. At first, it sounds (and is priced) like a bland textbook written by an academic. Actually, it's a set of stories about various White House successes and debacles, told from the perspective of a group psychologist. Janis pinpoints the moments where presidential advisers, on the verge of voicing their reservations about strategic decisions, were ultimately too timid to speak up. It gives a very unique perspective on executive decisionmaking and teaches the value of speaking your conscience, admitting your faults, and changing your mind when necessary.
