A specialized branch of political psychology that studies the psychological and behavioral processes that drive individuals and groups to political extremism and terrorist violence. This field includes the analysis of individual and collective motivations, emotions, identity, ideology, and social, economic, and political pressures that influence the propensity to terrorism. It also focuses on the mechanisms of recruitment, the influence of extremist groups on individuals, and methods to reinforce ideological affiliation and moral justification for violence. In addition, the psychology of terrorism aims to develop prevention programs, strategies to counter radicalization, and build community resilience to the negative psychological effects of terrorism, while understanding how the phenomenon affects political and social security in the long term.
