Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

An experiment produces evidence.
Mechanism: An experiment produces evidence: a controlled test yields observations that count for or against a hypothesis.

Scientific Method requires Experiment.
Mechanism: Testing hypotheses relies on controlled experiment.
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 · 6 of 6 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 6 → 14 → 48 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
- Its dependency reading rests on 1 foundation relation. structural
- 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.
What builds on this
2 concepts build on this directly, 2 in total, across 6 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
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 Prediction, Evidence and Hypothesis.
Through this lens it connects to Scientific Method and Scientific Instrument.
Related ideas to explore
Concepts that look related but are not yet connected here — candidates for a connection to reason about, not established links.

The same structure shows up in other disciplines. These are real recurrences drawn from the graph — a starting point for asking “what carries over, and what changes?”

An experiment tests an idea by changing just one thing at a time and keeping everything else the same, so that any difference in the result can be pinned on that one change.
Mental models at work here
- Connects 6 other ideas across 4 disciplines.
- A cross-disciplinary bridge — its connections reach into 10 other fields.
