The PRI is the measurement layer of Nervous System Intelligence (NSI).
It quantifies how quickly and cleanly a nervous system recovers after a perturbation., providing a real-time signal of readiness, resilience, or risk.

​

PRI captures dynamic recovery, not self-report, making it suitable for clinical, enterprise, and AI-safety environments where state-readiness must determine when action is safe to proceed.

​

This page will document the evolution of PRI as a safety metric, including:

• Measurement methodology (perturbation → recovery curve)

• Safe vs. unsafe thresholds (preliminary ranges)

• Pilot environments involving clinicians, AI-system designers, and enterprise leaders

• Future API-level integration — enabling human-AI systems to verify state capacity before high-stakes execution

​

PRI is currently in early applied research and model calibration, with Phase 1 validation targeting 2026 field deployment.
