The Core Emotion Framework (CEF) introduces a structural‐constructivist model of affective function that resolves the long‐standing nature–nurture debate by distinguishing innate emotional architecture from learned misuse. It defines ten universal Core Emotions organized into Head, Heart, and Gut centers, with Accepting as thefoundational base state. Pathology arises when Constricting fuses rigidly with action components, producing Structural Entanglement and the self‐perpetuating Vicious Cycle of compulsive obstinacy. Therapeutic resolution occurs through the Creative Insight Paradox—an “Aha!” moment of Structural Disassembly—where a suppressed emotion re‐emerges to shatter rigidity and restore functional separation. Sustained equilibrium requires continuous practice of Yielding, Discernment, and Elevation, enabling dynamic flexibility and non‐compulsive assertiveness. By reframing typological models as descriptive maps of pathology rather than identity, and byproposing validation protocols that measure structural integrity rather than trait intensity, the CEF positions itself as a diagnostic and therapeutic instrument for affective actualization and emotional regulation.
