A Relational Theory of Collective Intelligence

Collective intelligence in human teams is often described in cognitive or behavioral terms, yet empirical evidence increasingly shows that high‑performing groups behave as relational fields whose properties cannot be reduced to individual traits. This paper introduces a Relational Theory of Collective Intelligence grounded in a multi‑layer coherence model integrating physiology, communication, and meaning. Drawing on Grete Hermann’s relational interpretation of quantum mechanics—where physical properties arise only within specific measurement contexts—and on the Pauli–Jung concept of a psychoid domain linking psyche and matter, we propose that team performance emerges from interaction‑dependent coherence rather than from isolated individual capacities. We formalize this with a coupled‑oscillator model describing HRV synchrony, conversational rhythm, and subjective alignment, and we define a unified metric, the Team Resonance Index (TRI), as an order parameter of the relational field. A 30‑minute R&D team session demonstrates a measurable phase transition from fragmentation to collective intelligence following a brief coherence‑inducing intervention. Results show that physiological entrainment, vocal rhythm alignment, and shared meaning converge into a single relational structure that predicts team performance. We argue that collective intelligence is a field phenomenon analogous to relational structures in quantum theory, and we present TRI as the first operational measurement of this relational ontology.
