Beyond Fight-Flight-Freeze-Fawn: A Vector-Dynamics Framework of Human Threat Response with Deception and Assimilation Strategie

The classic four-factor model of acute stress responses—Fight, Flight, Freeze, and Fawn (4F)—has been instrumental in describing immediate, reflexive reactions to perceived threat. However, its explanatory power diminishes when applied to complex, socially embedded, and temporally extended human behaviors. This working paper proposes a conceptual extension termed the Vector-Dynamics Framework of Threat Response. The framework introduces three modifications: (1) a continuum of mobilization intensity rather than discrete categories; (2) two additional strategic dimensions—Deception (tactical imitation of a 4F response) and Assimilation (alliance-seeking); and (3) a vector equation wherein observable behavior results from the summation of multiple, often conflicting, internal and external pressures (e.g., immediate threat vs. social sanction). This paper outlines the theoretical novelty, distinguishes the model from existing cognitive appraisal theories, and formulates falsifiable hypotheses for future empirical investigation. The work is published as a preliminary preprint to establish priority and solicit critical feedback from the scientific community.
