The recalibration theory of anger suggests that anger serves an evolutionary purpose by motivating individuals to address perceived injustices and violations of social norms. Anger functions as a recalibration mechanism, signaling when individuals' goals or expectations have been thwarted and prompting them to take corrective action.

Central to this psychological model is the idea that anger is not merely a destructive force but a strategic tool that can be employed to negotiate social hierarchies, assert boundaries, and protect one's interests. Anger is seen as an adaptive response that has evolved to promote survival and reproductive success. By mobilizing physiological and psychological resources, anger enables individuals to confront challenges and overcome obstacles in their environment.
