Geography
A discipline is a lens, not an owner — the same idea can be viewed through many.
Concepts viewed through this lens
These numbers describe the current Thinking OS knowledge slice, not the whole field.
Disciplines it bridges to
Each bridge is built by ideas the two fields share, the thinking patterns that recur across both, and a representative relationship that shows how they connect.

Field shape — representation health
52/100 overall · 24 concepts
The eight dimensions measure Thinking OS coverage of this field, not the quality or importance of the discipline.
What kind of structure is this field?
Interpreted from the current atlas — how this field is represented, not a judgement of the field.
Representation health 52/100 — dense but shallow. Strongest: cross-disciplinary, taxonomy. Thinnest: factual depth, provenance.
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
83% of its relations reach into 55 other disciplines — an outward-facing field in the atlas.
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
Its 52 representation-health is below the 55 median of 206 similarly-sized disciplines (comparable by concept count).
structural · Measures the current Thinking OS representation, not the quality or importance of the field.
21% of its concepts have a single connection (mean internal degree 1.4) — a fairly cohesive internal structure.

Mental models that recur here
Feedback loop ×4
A loop where an effect feeds back to change its own cause. Reinforcing loops amplify change; balancing loops resist it.
Stocks and flows ×3
A stock is an amount that accumulates; flows are the rates that add to or drain it. The stock changes only when inflow and outflow differ.
Trade-offs ×2
When getting more of one thing means accepting less of another, because resources or constraints are limited.
Conservation ×1
Some quantity stays constant no matter how a system rearranges — it can move or transform but is never created or destroyed.
