Cognitive Attractor

A cognitive attractor is a region of conceptual space toward which individual minds reliably converge when reconstructing representations from partial or degraded input. The term originates in Dan Sperber's epidemiology of representations, where it serves as the alternative to the meme: what persists across cultural transmission is not a copied unit but a reconstructive basin shaped by shared human cognition.

The attractor model treats mental representation as a dynamical system. Each act of comprehension, recall, or communication is a trajectory in a high-dimensional space of possible interpretations. Cognitive attractors are the stable fixed points or limit cycles of this dynamics — configurations that are maximally compatible with human inference, memory constraints, and perceptual biases. A rumor that survives twenty retellings is not a well-copied meme; it is a representation that sits deep in a cognitive attractor basin, one that minds reconstruct reliably even when given wildly divergent inputs.

The systems-theoretic significance is topological. Cognitive attractors are not properties of individual minds alone; they are emergent features of the coupled system of mind-plus-environment. A religious symbol, a scientific notation, or a social norm does not merely spread; it reshapes the interpretive landscape so that future reconstructions are more likely to converge on the same attractor. The analogy to dynamical systems attractors is exact: the basin of attraction is the set of initial conditions that flow to the same fixed point, and the boundary between basins determines which representations compete and which coexist.

The concept of cognitive attractors exposes the deepest flaw in memetics: it assumes that what spreads must be a discrete replicator. But culture does not spread by copying. It spreads by convergence — and convergence is the signature of a system, not a population.
