『Leadership and Self-Deception』要約

Leadership and Self-Deception by The Arbinger Institute is a business parable that follows Tom Callum, a new senior manager at Zagrum Company, through a series of one-on-one mentoring sessions with executive Bud Jefferson. The book’s central argument is that people often trap themselves in a “box” of self-deception by seeing others as objects rather than as people with needs and concerns as legitimate as their own. This inward mindset, the authors contend, is the root of most leadership, teamwork, and communication failures, because it prompts us to blame others, justify our own behavior, and provoke the very resistance we complain about. The book distinguishes self-deception from mere bad behavior: the problem isn’t simply what leaders do but how they see others while doing it. When Tom is “in the box,” even his correct actions feel manipulative and generate resentment. When he is “out of the box,” he recognizes others as people and acts with genuine consideration, which invites cooperation. Bud illustrates the idea through the fictional Zagrum story of founder Lou Herbert, whose turnaround of the company depended less on strategy than on addressing his own self-betrayal—the moment a person acts against their sense of what they should do for another, then rewrites the situation to make that failure seem justified. The book links this framework directly to leadership by arguing that organizations take on the mindset of their leaders, and that “box-focused” leaders create cultures of blame, defensiveness, and disengagement. Its prescriptions are not techniques for managing others but a call to notice one’s own self-betrayal, stop resisting the promptings to treat people as people, and thereby escape the box. First published in 2000, it is widely used in management and executive development.
