Leon Festinger’s Social Comparison Theory Explained

Social comparison theory, first proposed by psychologist Leon Festinger in 1954, posits that individuals evaluate their own abilities, opinions, and outcomes by comparing themselves to others. The process helps people reduce uncertainty about themselves and maintain self‑esteem, often occurring when reference groups are similar.

Equity theory, later developed by J. Stacy Adams, expands on Festinger’s ideas by focusing on perceived fairness in the workplace. It argues that people assess the balance between their inputs (effort, skill, time) and outcomes (rewards, recognition) against those of a referent. When a discrepancy is perceived—such as a colleague receiving higher rewards for comparable inputs—stress and dissatisfaction may arise. Individuals can respond by adjusting their inputs, seeking better outcomes, reframing their perceptions, changing referents, or leaving the situation.
