THE SENTINEL PHENOTYPE: A Theoretical Bioenergetic and Neurobiological Framework for High-Fidelity Predictive Systems (HEPOE Theory)

ABSTRACT The HEPOE Theory (High Entropy Predictive Organization Efficiency) proposes a novel conceptual framework for understanding Giftedness (HA/G), moving beyond academic performance-based models toward a biophysical and neuroscientific foundation. Through a theoretical synthesis grounded in the Free Energy Principle and Biological Thermodynamics, the gifted individual is redefined as a 'Sentinel': a high-fidelity sampling system specialized in the early detection of isomorphy and the reduction of systemic entropy. This framework reinterprets Charles Spearman’s general intelligence (g) (2008) as a macroscopic manifestation of hardware efficiency, where reasoning ability is proposed to be fundamentally constrained by working-memory capacity and the metabolic economy of ATP resynthesis. We hypothesize that the hardware operates under an 'open sensory gating' regime and low latent inhibition, leading to high metabolic costs and chronic allostatic load. The paper introduces the original concept of Predictive Moral Injury (Brezolin and Freitas, 2026) to conceptualize the potential somatic damage resulting from the early perception of ethical-systemic collapses within low-resolution environments. The HEPOE Unification Matrix integrates decades of classical literature (Dabrowski, 1964; Silverman, 1993; Renzulli, 2005) and proposes a rigorous differential diagnosis against the pathologization of ASD, ADHD, and PTSD. It hypothesizes that the Sentinel’s exhaustion is not a dysfunction, but a logistical byproduct of high predictive performance under entropy-saturated conditions. Keywords: Sentinel Phenotype.
