Unfairness and Radicalization.

This article reviews the relationship between people's perceptions of unfairness and their tendencies to think, feel, and act in radicalizing ways. Various theories of radicalization processes are reviewed that examine key aspects of the psychology of perceived unfairness. The review shows that experienced group deprivation and perceived immorality are among the core judgments that can drive Muslim radicalization, right-wing radicalization, and left-wing radicalization. Symbols of injustice, the legitimization of revolutionary thought, and the experience of unfair treatment can also increase radicalization. The review also examines core moderators (e.g., uncertainty and insufficient self-correction) and mediators (e.g., externally oriented emotions) of the linkage between perceived unfairness and core components of radicalization (e.g., rigidity of thoughts, hot-cognitive defense of cultural worldviews, and violent rejection of democratic principles and the rule of law). The review discusses how the study of unfairness and radicalization contributes to a robust and meaningful science of psychology.
