Reusable cognitive primitives

Cause and effect

One thing genuinely bringing about another — as opposed to two things merely moving together. Establishing it needs a mechanism and controls, not just a pattern.

Where it appears

Dependencies & synergies

Derived from the graph’s real structure — 32 concepts across 35 disciplines carry this pattern. Every figure is a count, not a score.

Reach across disciplines

How many concepts carrying this pattern are seen through each discipline.

Patterns that travel with it

Other thinking patterns that recur on the same concepts — the more shared concepts, the more often they co-occur.

Examples across disciplines

Medicine

A trial asks whether a drug causes recovery, or whether patients would have recovered anyway.

Climatology

The physics of heat-trapping gases explains why rising CO₂ causes warming, not just accompanies it.

Economics

Ice-cream sales and drownings rise together, but summer heat is the hidden common cause.

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 35 disciplines over 32 carrier concepts — a broadly transferable pattern.

    structural · Structural recurrence in the atlas — a pattern is a reasoning lens, not a law.

  • 10 of its 32 carrier concepts are themselves cross-disciplinary connectors.

Common misconception

That things happening together (correlation) proves one causes the other.

Journeys where it shows up

Try a transfer challenge

You have seen this model in one place. Where else could it apply — and where would the analogy break?

Causation
The intuition

Ask: if I changed the cause, would the effect change? And what else might explain the link?

The reach of this pattern
  • Recurs across 35 disciplines.
  • 79 concepts exercise this thinking pattern.
  • It is practised in 1 learning journey.

Derived from the graph — a pattern is a reasoning lens, not a law.

How to recognise it

If you intervened and changed the suspected cause, would the effect move — or could a third factor be producing both?

Keep this question handy when you meet something new — it helps you notice the pattern, not just name it.
