The Idiosyncrasy Credit Model of Leadership, developed by Edwin Hollander, is a descriptive leadership theory that explores how leaders earn influence and acceptance from their followers over time. Rooted in social exchange theory, it focuses on the dynamic relationship between leaders and group members—particularly how leaders gain support for change and innovation through accumulated “credits” of conformity and contribution.
According to Hollander, leaders build idiosyncrasy credits—a form of “acceptance capital”—by demonstrating two core behaviors:
-
Competence: Making visible contributions to the group’s primary tasks, thereby proving value.
-
Conformity: Displaying loyalty to existing group norms and shared values.
When a leader earns enough credit through consistent conformity and task-related contributions, followers are more likely to accept deviations from the norm, including proposals for change and innovation. This leads to the core paradox of the model: to lead change, a leader must first build credibility by aligning with the status quo.
As summarized by George Homans, influence over others is granted in exchange for initially being influenced by them. For example, early conformity creates tolerance for future nonconformity, such as introducing innovative ideas or challenging the current structure.
The model is particularly significant for its:
-
Emphasis on the role of followers in the leadership process,
-
Attention to the temporal dynamics of influence, and
-
Insight into how social legitimacy is built over time.
Importantly, the Idiosyncrasy Credit Model is descriptive, not normative—it explains how leadership influence emerges in groups but does not prescribe how leaders should act.
