Fanaticism vs Rational Extremism Models

Abstract

Extremist behavior is often portrayed as irrational fanaticism driven by blind faith, emotional contagion, or ideological indoctrination. However, emerging research suggests that some acts of political or ideological violence may be motivated by calculated reasoning, strategic goals, and cost–benefit evaluations rather than pure zealotry. This paper compares psychological characteristics of fanatic extremism—driven by identity fusion, dogma, and emotional intensity—with rational extremism, where individuals justify violence through perceived logical necessity within a moral or political framework. Using conceptual analysis and hypothetical cross-national data, the study explores how these models intersect, how radical actors shift between them, and the implications for prevention, deradicalization, and policy. Results indicate that most extremist behavior lies on a continuum involving both emotional conviction and strategic rationalization.
