The clinical observation that cognitive insight frequently fails to resolve anxiety — that patients can know they are safe while simultaneously feeling endangered — represents a fundamental challenge to top-down models of psychotherapy. This paper formalizes this phenomenon as Limbic Friction in its purest temporal form: a measurable decoupling between the prefrontal cortex's capacity for Mental Time Travel and the subcortical defensive system's commitment to present-moment threat response. Drawing on recent large-sample neuroimaging evidence demonstrating that both the amygdala and the periaqueductal gray (PAG) are non-modifiable by cognitive reappraisal (Bo et al., 2023; N=358), Craske's inhibitory learning model of exposure therapy, and Borkovec's cognitive avoidance theory of worry, we propose the Temporal Displacement Model as the mechanistic explanation for why "knowing better" does not produce "feeling better." The model identifies three profile-specific temporal signatures — Architect (prospective hypervigilance), Radar (retroactive threat-scanning), and Special Forces (temporal fragmentation) — each requiring distinct intervention strategies that bypass the insight paradox by targeting the temporal mismatch itself rather than its cognitive content. Integration with the PAG ontogeny framework (Paper 7) and the Birth Pulse calibration model (Paper 0) positions temporal displacement as the adult expression of neonatal PAG gain-settings, completing the developmental arc from birth to clinical presentation.
