A1 Peter Principle

Topic

The starting point for this trajectory is legal-rational authority: unlike charismatic or traditional authority—which emerges from network centrality, perceived charisma, or an individual's accumulated credibility—legal-rational authority resides in an office rather than in the person holding it. A formal rule—such as an appointment, a contract, or an organizational chart—grants this authority to the office; the fact that authority resides in the office rather than the incumbent allows it to survive changes in personnel, persisting even when the officeholder is replaced.

Because membership in a community organized around these offices is a condition of a contract rather than a matter of free association, the legal-rational authority inherent in a specific office extends to entire communities built upon the same principle: corporations, armies, state bureaucracies, and institutional churches.

Formal organization emerges when the transaction costs of case-by-case coordination—whether via networks or markets—exceed the costs of coordination through authority within a hierarchy of offices; according to Ronald Coase’s argument, this is why such communities exist rather than all coordination occurring through free negotiation.

Within this hierarchy, offices are filled through promotions, and the prevailing promotion criterion bases the decision exclusively on the individual's performance in their previous role. If the correlation between performance in the previous role and performance in the current role drops to zero or becomes negative—while the promotion criterion remains rooted solely in past performance—individuals rise to the level of incompetence described by the Peter Principle: the incumbent fails to perform well in the current role, yet the criterion that led to their promotion cannot detect this failure because it looks only at the previous role. That is why the Peter Principle serves—within the framework of the legal-rational authority that opened this path—to pinpoint the exact moment when that authority (granted by a formal rule to a position rather than a person) ends up assigned, within a formal organization's hierarchy, to someone whose performance in their current role no longer bears any relation to the performance in the previous role that earned them the promotion.
