Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
System context
Hierarchyis aPatternEstablished
Hierarchy is a structural pattern of levels.
Mechanism: A hierarchy is a pattern of nesting: parts group into wholes that group into larger wholes, organising complexity into levels.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
50% of its relationships cross field boundaries, reaching 7 other disciplines — above the 23% median of 8 concepts in the same discipline.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no verified source · no key date stored · 2 of 2 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 2 → 13 → 61 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 50% of its relationships cross field boundaries. structural
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Emergence
When many simple parts interacting by simple rules produce a pattern or behaviour that none of the parts has on its own.
Ask: is this property in the parts, or only in how they interact?
Scale
How a system's size changes what matters about it. Quantities rarely scale in step: doubling a length can quadruple an area and multiply a volume eightfold.
Ask what changes when you make it ten times bigger or smaller — the rules often change with the size.
- Connects 2 other ideas across 5 disciplines.
- A cross-disciplinary bridge — its connections reach into 7 other fields.
- Most of its connections are of the “Kind & structure” kind.
- It exercises 2 reusable thinking patterns.
Derived from the graph’s real structure — observations, not a score.
