signaling

Signaling is a human-made mechanism by which one party conveys information about unobservable qualities — intent, capability, commitment, or type — to another party through observable actions or symbols. Parameters: (1) a sender who performs a signal-bearing action, (2) a receiver who interprets that action, (3) an unobservable trait or state being communicated, (4) a shared symbolic system that maps actions to meanings (e.g., language, gestures, visual markers). The signal must be costly or difficult to fake relative to what is being communicated; without this costliness, cheap talk replaces signaling. The persistence mechanism is cultural transmission — signals are learned, taught, and reinforced through repeated interaction within a community. Signals persist across generations through institutionalization (rituals, norms, conventions) and through the self-reinforcing nature of shared meaning: the more participants accept a signal's meaning, the more valuable it becomes as a coordination tool. Signaling operates as a bridge between private information and public action. [formal: signum | substrate: behavior | horizon: a life | explicit: yes | epoch: 0.01]
