# Hierarchy **Domain:** Social Organization / Primatology / Institutions **Doc Type:** Concept Node **Maturity:** Developing ## Definition **Hierarchy is an ordered distribution of rank, authority, access, responsibility, or influence within a group or system.** Hierarchies can reduce coordination costs, preserve expertise, and clarify responsibility; they can also conceal extraction, block correction, or let rank substitute for competence. ## Biological and Institutional Registers Dominance structures in social animals provide evidence that rank behavior predates human institutions. They do not prove that one political arrangement is natural, permanent, or good. Human hierarchy operates through biology, culture, reputation, law, property, organizations, technology, and deliberate design. [[wiki/Leadership|Leadership]] concerns the conduct exercised within or across those structures; [[wiki/Primate Politics|Primate Politics]] tracks older rank and coalition mechanisms that institutions redirect. ## Simple Reminders, Quotations, and Thoughts > “Hierarchy has biological roots. Primatologists find dominance structures in nearly every social primate species, and the best-functioning groups are led by individuals the group trusts. Human hierarchy works well under trusted leaders and turns harmful when the wrong people exploit it.” > **— Bryant McGill**, *Emergence, Compounding Effort, and the Architecture of a Mission - Livestream (Aug 2016)* [[reminders/Leadership/Trusted Leadership Makes Hierarchy Work by Bryant McGill|Trusted Leadership Makes Hierarchy Work by Bryant McGill]] ## Relationships [[wiki/Leadership|Leadership]] · [[wiki/Primate Politics|Primate Politics]] · [[wiki/Human Animality|Human Animality]] · [[wiki/Institutional Trust|Institutional Trust]]
