Romantic jealousy as a social comparison outcome: When similarity stings

Two studies examined the role of perceived self-rival similarity in the experience of romantic jealousy, which is assumed to reflect threats to self-evaluation. Self-other similarity is one factor that determines whether social comparison yields assimilation or contrast. Based on the premise that people want their romantic partners to see themselves positively, it is predicted that people experience greater jealousy when comparing with an attractive rival in terms of similarities because similarity challenges one’s positive distinctiveness. People should also experience greater jealousy, however, when they compare themselves with an unattractive rival in a manner that renders their own weaknesses salient during the comparison process. The results support the ‘distinctiveness hypothesis,’ but are inconsistent with cognitive models of social comparison, which posit that people see themselves more positively either when their self-evaluations are assimilated to superior others or contrasted away from inferior others.
