Elliot Aronson
Elliot Aronson (born January 9, 1932) is an American social psychologist and professor emeritus of psychology at the University of California, Santa Cruz, recognized for pioneering empirical research on cognitive dissonance theory, which elucidates how individuals reconcile inconsistencies between their beliefs and behaviors to preserve self-esteem. [1][2][3]
Aronson's refinements to cognitive dissonance emphasized its roots in threats to self-concept rather than mere inconsistency, influencing subsequent studies on attitude change, decision-making, and self-justification. [4]
In applied domains, he developed the jigsaw classroom technique in the early 1970s, a cooperative learning method that assigns interdependent roles to students to foster empathy, reduce prejudice, and enhance academic performance in diverse settings, initially implemented to address tensions in desegregated schools. [5][1]
Aronson is the sole recipient in the American Psychological Association's 110-year history to earn its top honors across research, teaching, and writing categories, underscoring his impact on both theoretical and practical social psychology. [3][6]
His work extends to interpersonal attraction, conformity, and real-world interventions for issues like energy conservation and prejudice mitigation, grounded in controlled experiments that prioritize causal mechanisms over correlational assumptions. [4][7]
