--- Diane Vaughan, Boston College

"A lively updating of a classic, in many ways superior to the original."
--- Richard K. Betts, Columbia University

"The revised edition updates both the theory and the history in a compelling manner. It is an impressive achievement."
--- Scott Sagan, Stanford University

"More than a revised edition, this is a new book, with the most recent empirical material and sophisticated theorizing. Important as it was, the original Essence of Decision now appears to have been a first draft; this version was worth waiting for."
--- Robert Jervis, Columbia University
