Reinforcing loopcausesExponential growthEstablished
Reinforcing loops drive exponential growth.
Mechanism: When more leads to even more — interest earning interest, infections causing infections — the loop feeds itself and the curve bends sharply upward.

Tipping pointemerges fromReinforcing loopStrongly supported
Tipping points arise when a reinforcing loop takes over.
Mechanism: Past a threshold, a self-amplifying loop dominates and the system races to a new state — melting ice exposing dark water that absorbs more heat and melts more ice.

System context
Reinforcing loopis aFeedbackEstablished
A reinforcing loop is a kind of feedback.
Mechanism: A reinforcing loop is feedback that amplifies: the output feeds back to push the same change further, producing runaway growth or collapse.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 5 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 4 of 4 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: 4 → 31 → 137 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.

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?
Compounding
When each step's growth is added to the base so the next step grows too — producing accelerating, exponential change rather than a steady line.
Growth that feeds on itself starts slow and then surprises you.
