Emergenceemerges fromSystemStrongly supported
Emergent properties arise from a system's interactions.
Mechanism: Emergence is when a system does what its parts alone cannot: simple interactions among many parts give rise to new, whole-level behaviour.

System context
Climateis aSystemEstablished
Climate is a complex system.
Mechanism: Air, oceans, ice and life interact through flows and feedbacks; climate behaviour emerges from those interactions, not from any part alone.

Feedbackis part ofSystemEstablished
Feedback is a core feature of systems.
Mechanism: Feedback is a system connecting to itself: an output loops back as an input, so the system responds to its own behaviour.

Stockis part ofSystemEstablished
Stocks are the accumulations inside a system.
Mechanism: A stock is a system's memory: an accumulation — of water, money or population — that rises and falls with the flows into and out of it.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 5 of 5 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Exercises 3 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 5 → 51 → 174 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
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
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Mathematical model, Feedback and Stock.

A system is a group of parts connected so that they affect each other. What the system does — stay steady, grow, collapse — comes from how the parts are linked, not just from the parts themselves.
Mental models at work here
Stocks and flows
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.
Think of a bathtub: the water level (stock) rises or falls depending on the tap (inflow) and the drain (outflow).
Feedback loop
A loop where an effect feeds back to change its own cause. Reinforcing loops amplify change; balancing loops resist it.
Ask: does the result push the system further in the same direction, or pull it back?
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?
