# Does this organization (O) exist in the mind, and in what minds produce?

## The research claim

Cognitive science has many accounts of what minds do with information — schemas, categories, chunks, scripts, dual processes, predictive coding. Each describes a mechanism. None claims to name every structure a thought can have. None states what would show it was wrong. This one does. Every mental model is organized by the same four patterns, eight elements, and four dynamics. Not most models. Not models in certain domains. Every single one. The claim runs through to whatever a mind makes durable. A paper, a diagram, a theory, a trained neural network — each is a mental model set down in a form that outlasts the thinking. If the universal structures of DSRP-484 are complete within the process of thought, they will also render as structures in what thought produces.

## What would confirm it

Every mental model is organized by the four patterns, eight elements, and four dynamics. No mind, on any task, needs a fifth pattern, a ninth element, or a fifth dynamic. The same holds for anything a mind makes durable — a paper, a diagram, a theory, a trained model. Read in symbols: for every (∀) mental model (m) among all mental models (M), the organization of that model (O(m)) is identical to (≡) — not merely described by — the four patterns, eight elements, and four dynamics (DSRP-484).

## What would refute it

Some mental model is organized by something the calculus does not name. One mind, on one task, needs a fifth pattern, a ninth element, or a fifth dynamic. Read in symbols: there exists (∃) at least one mental model (m) among all mental models (M) whose organization (O(m)) is not identical to (≢) the four patterns, eight elements, and four dynamics (DSRP-484). A universal claim is denied by a single case, so one model is enough.

## The evidence, and why this status

Eighteen experiments sit behind this, in four programs, one per pattern. Within each program the studies use different materials and different tasks — sorting objects, labelling shapes, describing an inkblot, clicking a place in a picture — so a result that depended on one task would not survive the program it belongs to. Then the evidence widens past the laboratory, and the widening is the point. The same structure has been found in free description, in sorted objects, in written language, in published academic papers, and in machine models trained by people. Those are all products of minds, and none of them is an experiment. Three studies guard against the obvious objection, which is that coders find what they are looking for. One scored 600 items from standard language benchmarks on features fixed before scoring, with the scores computed arithmetically so no judgement entered at that stage. One is an independent replication on a different sample by a different method, network analysis of written language. And one is not about people at all — nine combinations of dataset and machine-learning architecture, where the criterion came from outside and the model either got it right or did not. One result is worth naming because it could have gone the other way and did not. Asked to select everything that is not a red circle, people negated one feature at a time, in order of how many features each option negated. Random selection was available. So was negating everything at once. Neither happened.
