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.
Foundations · builds on
Game theorydepends onProbabilityEstablished
game theory depends on Probability.
Mechanism: Game theory rests on probability: mixed strategies and expected payoffs are built from the odds players assign to each other's moves.

System context
Dominant strategyis part ofGame theoryEstablished
A dominant strategy is always best.
Mechanism: It yields a player the highest payoff regardless of the others' choices, so a rational player will take it.
Nash equilibriumis part ofGame theoryEstablished
Nash equilibrium is part of game theory.
Mechanism: The Nash equilibrium is a central solution concept of game theory: a set of strategies where no player can do better by changing theirs alone.

Payoff matrixis part ofGame theoryEstablished
The payoff matrix describes a game.
Mechanism: It tabulates each player's reward for every combination of strategies, the raw data of the analysis.
Prisoner's dilemmais part ofGame theoryEstablished
prisoner's dilemma is part of game theory.
Mechanism: The prisoner's dilemma is the classic game of game theory: rational individual choices lead to a worse outcome than cooperation would.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
11% of its relationships cross field boundaries, reaching 6 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: 9 of 9 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: 9 → 46 → 142 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
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.
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 Economics, Prisoner's dilemma, Nash equilibrium and Public choice theory.
Through this lens it connects to Probability, Nash equilibrium, Dominant strategy and Payoff matrix.
