Acumulatius

Acumulatius is a hypothetical term used in discussions of complex systems to describe a broad pattern in which resources, influence, or attention tend to concentrate in a minority of components over time. It serves as a heuristic for describing emergent concentration effects that are not tied to a single mechanism.

The term is informal and not part of a formal scientific taxonomy. It draws on a Latinate form from accumulare, but there is no canonical definition or measurement standard. In practice, acumulatius is used to indicate that small initial differences can be amplified by feedback processes, leading to disproportionate accumulation.

Mechanisms commonly associated with accumulatius include positive feedback, preferential attachment, network effects, and diminishing returns to dispersion. Models often employ agent-based simulations or differential equations to illustrate how small asymmetries can produce large concentrations.

Contexts where the concept is discussed include ecology (nutrient or contaminant accumulation in a reservoir), economics (wealth or capital concentration), and information systems (attention or data gathering at centralized nodes). It is sometimes invoked to compare with related ideas such as concentration, aggregation, or the Pareto principle, though acumulatius emphasizes the dynamical path to concentration.

Critiques note that the term can be vague and overlapping with established concepts; without precise definitions or metrics, its explanatory power can be limited. Proponents argue it helps frame cross-disciplinary observations of uneven distributions and systemic inertia.
