NEW EXPANDED EDITION includes new chapter on how others have used the book in their organizations. For too long, the issue of self-deception has been the realm of deep-thinking philosophers, academics, and scholars working on the central questions of the human sciences. The public remains generally unaware of the issue. That would be fine except that self-deception is so pervasive it touches every aspect of life. Touches is perhaps too gentle a word to describe its influence. Self-deception actually determines one's experience in every aspect of life. The extent to which it does that, and in particular the extent to which it is the central issue in leadership, is the subject of this book.
