Social comparison theory, developed in 1954 by Leon Festinger, explores the natural need individuals have to compare themselves to others when they lack tangible benchmarks for evaluating their own behavior. By choosing role models, they seek to identify the traits they wish to adopt. Fundamentally, this theory emphasizes the importance for each individual of understanding their own opinions, beliefs, values, skills, and emotions in order to feel fulfilled and perform well. According to George Moschis, social comparison revolves around two distinct processes: reflective appraisal and comparative appraisal, which allow an individual to situate themselves in relation to a reference group and to acquire information about themselves.
