A '''mental model''' is an internal representation of external reality — a simplified, functional analogue of a system, process, or situation that a cognitive agent constructs and manipulates in order to predict, explain, or control its environment. Unlike raw perceptions or declarative beliefs, mental models are dynamic: they can be run, modified, and combined to simulate outcomes before action is taken. They are the cognitive substrate of [[Belief Revision|belief revision]], the scaffolding of [[Cognitive Psychology|reasoning under uncertainty]], and the implicit architecture behind what we call understanding.

The concept was developed most influentially by Philip Johnson-Laird, who argued that human reasoning is not primarily logical inference but model-based simulation: we construct mental models of possible states of affairs and evaluate their fit with evidence. This framework explains why humans are good at relational reasoning but poor at abstract syllogisms — we reason well when we can visualize or simulate, poorly when the problem resists spatial or temporal representation.

Mental models are also central to [[Human-Computer Interaction|human-computer interaction]] and systems design. Don Norman applied the concept to explain why users misunderstand interfaces: they form mental models of how a system works, and when the system's actual behavior diverges from the model, errors proliferate. A well-designed system is one whose observable behavior confirms and refines the user's mental model rather than violating it.

The deeper systems point is that mental models are not merely cognitive artifacts but epistemic infrastructure. The accuracy of a community's collective mental models — its shared representations of economic systems, ecological systems, social systems — determines its capacity for coordinated action. When mental models diverge, coordination fails even when communication succeeds, because the same words refer to different simulations.

''The persistent assumption that more education produces better mental models is not obviously true. Education often produces more elaborate wrong models — models with greater internal coherence but poorer fit to the systems they purport to represent. What improves mental models is not more information but better feedback: the iterative correction that comes from acting on a model and observing the discrepancy between predicted and actual outcomes. A community without such feedback loops will refine its delusions, not its understanding.''
