Glossary

These entries define words used in a precise, structural sense throughout this argument. Many of them also appear in ordinary speech; here each one names a specific idea, not a loose synonym for “healthy,” “toxic,” or “effective.” Where two terms contrast—renewal and erosion, circulation and correction—the entries spell out how they differ.

Circulation — Whether influence can move through temporary or shared leadership (including guest leadership) so that leadership can scale without fixing every role at the top: how leadership spreads and reproduces itself, including what Leadership Reproduces Itself points to when people imitate what last worked. The permission question—whether stepping in, being credited, and stepping back are safe in practice—is often settled through repeated example before anyone tests it formally. Not the same as correction, which is a different structural problem: whether warnings and dissent can change decisions without punishment.

Correction — Whether warnings, dissent, and what people on the ground see can reach decision-makers and change direction without punishment—return paths for feedback and revision. Contrasts with narrow or one-way channels; not the same as circulation.

Adaptability — The capacity of coordinated action to change direction when reality pushes back. Together with scalability, it sorts groups into the four states adaptive, entrenched, regenerative, and stalled, and underpins how renewal and erosion are read.

Decay — The state of a group when capacities shrink: influence no longer changes course readily under pressure, coordinated action no longer sustains reach, or both. Contrasts with vitality; sustained erosion tends toward decay.

Effectiveness — What gets amplified, deferred, or mistaken for control when people look to leadership—not the same as morality or intent.

Erosion — The direction in which a group moves when scalability or adaptability shrinks—toward insulation, narrowed correction, and broken reach. Contrasts with renewal; it names structure, not moral worth.

Guest leadership — A form of circulation: people closest to an issue can temporarily step in to lead a response, then return to their usual role.

Harm — Where cost lands when influence is exercised: who absorbs it, who is kept in view, and what displacement is treated as acceptable.

Legitimacy — What makes authority feel usable to those who follow: grounding in real behavior, in rules and roles, in the office itself, or in something closer to identity and shared story.

Renewal — The direction in which a group stays open to course correction and keeps coordinated action working as reach grows. Contrasts with erosion; sustained renewal tends toward vitality.

Scalability — The capacity of coordinated action to grow in reach. Together with adaptability, it sorts groups into adaptive, entrenched, regenerative, and stalled, and underpins how renewal and erosion are read.

Vitality — The state of a group when influence can sustain coordinated action as reach grows—how open the group is to revision and how workable coordination remains in the moment. Contrasts with decay; sustained renewal tends toward vitality.
