What is jealousy?
Jealousy is a three-party emotion: a person fears losing something they value — typically a close relationship — to a real or imagined rival. The three components are the self, the partner (whose attention or affection may be diverted), and the interloper who threatens to take it. This triadic structure distinguishes jealousy from envy, which is dyadic.
Key concepts
Jealousy
A three-party emotion involving the self, a valued relationship partner, and a rival who threatens to usurp that relationship. Distinct from envy (which involves wanting what another has). Jealousy centres on fear of loss of an existing valued relationship or possession.
Romantic jealousy
Jealousy specifically in the context of a romantic or sexual partnership. Involves fear that a rival will attract the partner's romantic, sexual, or emotional attention. Considered cross-culturally universal but its triggers and expressions vary by culture and individual attachment style.
Sexual vs. emotional jealousy
A distinction in the evolutionary literature between distress provoked by a partner's sexual infidelity and distress provoked by a partner's emotional intimacy with a rival. Buss et al. (1992) proposed a sex difference: men more distressed by sexual infidelity, women more distressed by emotional infidelity. The finding remains controversial.
Mate retention
Behaviours aimed at keeping a romantic partner from leaving or being taken by rivals. From an evolutionary perspective, jealousy motivates mate retention tactics — vigilance, monopolisation of the partner's time, derogation of rivals. These can range from prosocial (investing in the relationship) to coercive and controlling.
Attachment and jealousy
Attachment style predicts jealousy intensity. Anxiously attached individuals experience jealousy more intensely and more frequently, interpreting ambiguous cues as threats to the relationship. Avoidantly attached individuals may suppress jealousy or deny threats. Secure attachment is associated with lower jealousy and more constructive responses.

Frequently asked questions
What is the triadic structure of jealousy and why does it matter?+
Jealousy involves three parties: the self, a valued partner, and a rival. The jealous person fears that the rival will take something — attention, affection, status, resources — from the valued relationship. This is structurally different from envy, which involves only two parties (self and the person who has something desirable). Recognising the triadic structure explains why jealousy is bound up with relationships and loss, while envy is bound up with desire and upward comparison.
What does evolutionary psychology say about gender differences in jealousy?+
Buss et al. (1992) proposed that men evolved greater sensitivity to sexual infidelity (because male reproductive success depends on paternity certainty, which sexual infidelity threatens) while women evolved greater sensitivity to emotional infidelity (because female reproductive success depended on male resource investment, which emotional infidelity threatened). Critics argue the measured gender difference is small and context-dependent, largely produced by forced-choice questionnaire designs; when continuous measures are used, both sexes are more distressed by emotional infidelity. Cultural variation also challenges a straightforwardly evolved universal.
How does attachment style shape jealousy?+
Anxiously attached individuals — who have negative models of the self and worry about abandonment — experience the most intense and frequent jealousy, and are most likely to interpret ambiguous partner behaviour as evidence of a threat. Avoidantly attached individuals tend to suppress or deny jealousy, consistent with their deactivating attachment strategies. Securely attached individuals feel less threatened by potential rivals and respond to jealousy with more constructive communication and less coercion.
