Predictive Use of a Universal Scaling Fingerprint

A universal scaling fingerprint characterized by an approximately invariant quantityQ(m)=mΔ(m)≈2 has been observed across multiple unrelated domains.Here we explore a minimal predictive use: deviations from the invariant plateauserve as an early-warning indicator for impending regime change.We present a simple forecasting protocol based on tracking the stability of theQ(m) plateau over time and show how this converts a descriptive scaling signatureinto a falsifiable prediction rule.
