Tagging (Complex Adaptive Systems)

Tagging is one of the four fundamental properties Holland identified in complex adaptive systems, alongside aggregation, nonlinearity, and flows. A tag is any marker that determines interaction eligibility — molecular surface proteins that bind antibody to antigen, prices that determine which transactions occur, organizational roles that determine who meets with whom. Without tags, every agent would interact with every other agent and the system would dissolve into noise. Tags create structure by constraining the interaction space, producing channels along which resources, information, and influence flow. The tagging architecture determines the system's emergent properties. Change the tags and the emergent properties change — sometimes dramatically, sometimes catastrophically. For AI-era organizations, every decision about tool deployment, team structure, performance measurement, and collaboration norms is a tagging decision, and the dissolution of functional tags under AI pressure is reshaping organizational emergence in ways most management theory cannot see.
