The Decoupling Threshold: Measuring Cognitive Variance Under Executive Stress

Executive cognition functions differently under prolonged ambiguity than in controlled laboratory simulations. In this empirical study, the Core16 research team monitored 12,400 senior executives across aerospace, healthcare, and quantitative finance over a 36-month horizon. Using continuous 64-vector telemetry, we identified the exact mathematical inflection point—termed the Decoupling Threshold—at which secondary cognitive traits decouple from primary executive governance, leading to predictable decision fatigue and tactical tunnel vision.
