The Science of Romantic Jealousy: Why Your Brain Scans for Threats, and Why Ruminating Makes It Worse

3 the researchers behind it — "I'm not a jealous person — I just need to know" is one of the most common lies jealousy tells about itself. The research tells a more structural stor

Yale University

Peter Salovey

Known for:Pioneer of jealousy and envy research, distinguishing the two constructs empirically and establishing that social comparison processes and domain-specific self-esteem are central drivers of romantic jealousy intensity

Key findings

  1. 1985

    With Judith Rodin, Salovey demonstrated that jealousy and envy are empirically distinct — jealousy involves a threat to a valued relationship, envy involves wanting what another has — and that jealousy intensity is predicted not by the rival's global attractiveness but by the rival's superiority in the specific domain where the jealous person feels most self-consciously inadequate. ↗

David Buss

Known for:Evolutionary psychologist whose cross-cultural research on sex differences in jealousy — sexual vs. emotional infidelity cues — became one of the most debated findings in relationship science, interpreted through parental investment theory

Key findings

  1. 1992

    Buss and colleagues found that men reported significantly more distress at imagined sexual infidelity and women at imagined emotional infidelity — a pattern interpreted as reflecting different adaptive concerns: paternity uncertainty for men, resource and commitment diversion for women. The finding spawned decades of replication attempts and methodological critiques. ↗

University of Hawaii

Gregory L. White

Known for:Developer of one of the first formal threat-appraisal models of romantic jealousy, framing jealousy as a relational appraisal process driven by perceived relationship value and rival threat, not as a simple emotional response

Key findings

  1. 1981

    White proposed a social exchange model of jealousy in which jealousy emerges when a person perceives that a rival threatens a relationship they value. Crucially, both the perceived value of the relationship and the perceived threat level of the rival are subjective appraisals — meaning jealousy can be triggered by imagined rivals and can be disproportionate to the actual threat. ↗
