# What is culture (ℂ), and where does it live?

## The research claim

Ask where culture lives and the answers point away from the head. Bourdieu put it in the body — habitus is disposition, drilled in by repetition, not represented and not available to introspection. Material culture puts it in objects and buildings. Distributed cognition puts it in the environment and the tools. Institutional accounts put it in rules and roles that persist whatever anyone believes. Schein and Hofstede describe its contents — values, norms, artifacts, dimensions — without settling the question at all. Culture is the mental model a group holds in common: ℂ ≡ 𝕄_α = I_αO_α, |α| > 1 Two people or two million, differing in size and not in kind. Culture is not the values it contains but the organization that holds them: what the group distinguishes, what it treats as part of what, what it relates to what, and from what point of view. The second half of the claim is the one that carries risk. Everything cultural that appears to live outside a head is downstream of a shared model, along one chain: shared model → action → embodiment, artifacts, environment, institutions A habitus is a shared model enacted so often it runs without deliberation. An artifact is action that left a residue. An institution is a shared model with roles attached and enforcement around it. A ritual is the structure performed. None of these is a rival location for culture. Each is its trail. So the disagreement with the incumbent accounts is not about where to look. They are looking at real things. The claim is that they are looking downstream, and mistaking the residue for the thing that made it. The consequence is that culture stops being a mood and becomes a thing with parts, and the parts are the ones any model has.

## What would confirm it

Culture is whatever a group holds in common as a mental model — and everything cultural that seems to live outside a head was produced by one. Read in symbols: culture (ℂ) is identical to (≡) the mental model held by a group (𝕄_α), which is that group's information times that group's organization (I_αO_α), where more than one agent holds it (|α| > 1). And for every (∀) cultural phenomenon x — a practice, a building, a ritual, an institution — x lies downstream of some shared model. The first half says what culture is. The second says that the things people point to instead are its products, not its location.

## What would refute it

Culture is something other than a shared mental model, or there is a cultural phenomenon that no shared model ever produced. Read in symbols: culture (ℂ) is not identical to (≠) a group's mental model, or (∨) there exists (∃) some cultural phenomenon x that is downstream of no shared model at all. The second disjunct is the live one. If a practice is transmitted body to body and was never anyone's model at any point in its history, then culture has a location outside the head and the chain is broken.

## The evidence, and why this status

If a mental model is information times organization, then culture cannot be a list of contents. Values, norms, rituals and artifacts are outputs. Something holds them, and on this account what holds them is a mental model a group has in common — which makes culture the same construct as a mind's model, differing in size rather than in kind, and gives it the properties models already have. The evidence here is derivation plus application, and it is honest about being that. The formal entry derives the collective form: attractors shaping a shared model, a coupling matrix for how individual cognition scales into a cultural field, and an adaptivity condition that turns out to be the individual alignment loop one level up. The paper says plainly it is a derivation. A companion supplies the operator that carries between the two, so that learning for one mind and learning for many are written the same way rather than by analogy. The applied entries show groups behaving as the construct predicts. An organization under strain where the parties disagreed about how the situation was organized rather than about values. A university's pandemic response. A human rights organization read from its founding. One appears in a top-tier operations journal outside this lab's venues. None of these traces the chain the claim actually asserts — habitus as enacted model, artifact as residue of action, institution as model with roles attached. What they establish is that a group's model can be described and that what the group did followed from it. That is initial evidence for the construct, not a test of its mechanism.
