Reusable cognitive primitives
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.
Where it appears
Dependencies & synergies
Derived from the graph’s real structure — 18 concepts across 24 disciplines carry this pattern. Every figure is a count, not a score.
How many concepts carrying this pattern are seen through each discipline.
Other thinking patterns that recur on the same concepts — the more shared concepts, the more often they co-occur.
What kinds of relationships the carrying concepts form — the relational signature of the pattern.
Concepts where this pattern does the most cross-disciplinary work — each reaches disciplines beyond its own.

How this pattern travels
Interpreted from where the pattern recurs in the atlas — structural transfer and coverage, not a claim it is universally the "best" model.
Recurs across 24 disciplines over 18 carrier concepts — a broadly transferable pattern.

How settled its carriers are
Epistemic status of the concepts that exercise this pattern.
✕ That exponential growth continues forever; real systems hit limits that bend the curve.
You have seen this model in one place. Where else could it apply — and where would the analogy break?
Compound interest →Growth that feeds on itself starts slow and then surprises you.
- Recurs across 24 disciplines.
- 48 concepts exercise this thinking pattern.
Derived from the graph — a pattern is a reasoning lens, not a law.
Is each period's growth added back to the base so the growth itself grows — turning a slow start into a steep curve?
Keep this question handy when you meet something new — it helps you notice the pattern, not just name it.
