plynem

Plynem is a fictional term used in theoretical discussions of multi-layer networks and complex systems. It denotes a unitless measure intended to capture the degree to which different layers of a system—such as social, economic, and technological layers—are cohesively aligned in their dynamics. In narrative and design contexts, plynem provides a compact way to describe systemic synchrony or discord across domains.

Definition and computation: In hypothetical frameworks, the plynem value ranges from 0 to 1 and is computed as the weighted average of cross-layer alignment scores. For each pair of layers, a score is calculated based on similarity of states, timing of interactions, and influence weights, then aggregated across all nodes and normalized by total weight. A higher plynem indicates stronger cross-layer coordination.

Etymology and status: The term is an invented construct without a standardized real-world basis. It appears in speculative literature and theoretical exercises, and in some design dictionaries as a compact shorthand for multi-layer coherence. There is no widely accepted empirical method for measuring plynem outside synthetic models.

Applications and limitations: Proponents use plynem in thought experiments to explore how policies, technologies, and cultural practices can propagate coherently across layers. Critics note that without empirical grounding it remains a heuristic, and its practical meaning depends on the definitions of the layers and alignment criteria chosen for a given model.
