Model I Theory-in-Use

Definition

Model I is the nearly universal default theory-in-use in industrialized societies. It is governed by four imperatives: (1) be in unilateral control, (2) win and do not lose, (3) suppress negative feelings, (4) act as rationally as possible. Shaped by these values, people advocate their positions, make evaluations and attributions about others in ways designed to maintain control, maximize chances of winning, and protect themselves from embarrassment. Because questioning one's own position risks losing control and looking vulnerable, Model I encourages neither inquiry into one's views nor robust testing of claims made.

In the Book

Argyris establishes Model I as the underlying cause of flawed advice and organizational dysfunction. Because nearly all people—regardless of age, education, wealth, or culture—operate from Model I, the organizations they build are consistent with it. Model I action creates predictable consequences: defensiveness, self-fulfilling prophecies, self-sealing processes, and escalating error. These consequences reinforce the need for unilateral control, winning, suppressing feelings, and appearing rational, creating a closed loop.

People governed by Model I are skilled at it. They act in ways that appear spontaneous and effortless because they learned these patterns so early that the skillfulness produces "designed ignorance"—they no longer need conscious attention to maintain the behavior. This is why people programmed with Model I remain blind to its counterproductiveness. Their very skillfulness at the behavior makes them unaware of the failure it produces. The book documents how leaders, consultants, and managers—well-intentioned and capable people—consistently operate from Model I, advocating positions unilaterally, making untested attributions about others' intentions, and suppressing inconvenient truths in the name of remaining positive and rational.

Why It Matters

Understanding Model I explains why most contemporary advice on leadership, change, and commitment fails. The advisors themselves operate from Model I; they remain blind to gaps and inconsistencies in their reasoning because their theories-in-use prevent them from inquiring openly or testing their claims robustly. They advise others to be authentic, participative, and open—yet they suppress their own doubts and act unilaterally when their authority is questioned. The advice fails not from poor execution but from being based on a theory of action that, by definition, produces defensive routines and prevents the very learning and authenticity the advice claims to promote.
