Narcissistic individuals and those with psychopathic tendencies are more likely to strongly endorse left-wing antihierarchical aggression, according to new research published in Current Psychology. Antihierarchical aggression refers to a specific type of hostility aimed at challenging or opposing hierarchical power structures or authority figures. The new findings shed light on psychological mechanisms that motivate some individuals to participate in violent political activism. The majority of research on authoritarianism has focused on individuals with right-wing political ideologies. This focus has resulted in a gap in understanding authoritarianism among individuals who support left-wing political ideologies, which the authors behind the new work sought to address.
