One of the most common signs of jealousy is an individual frequently comparing themselves to others. This may manifest as negative comments or feelings of inadequacy when faced with someone else’s success or achievements. According to Festinger’s Social Comparison Theory, people engage in these comparisons to evaluate their own worth, which can foster jealousy when they feel outperformed by others (Festinger, 1954).

Jealous individuals may express their feelings indirectly through passive-aggressive behaviour. This can include sarcastic comments, backhanded compliments, or subtle acts that undermine the success or happiness of the person they feel jealous of. This behaviour is often a defensive mechanism to conceal the vulnerability or insecurity they feel, as outlined by the American Psychological Association (APA, 2013).

Another indicator of jealousy is the constant need for validation and attention. A jealous person might feel threatened when others receive praise or acknowledgment, driving them to seek attention more aggressively. This behaviour stems from insecurity and fear of being overlooked or undervalued (Cohen & Pressman, 2015).

Jealousy can lead to controlling tendencies, particularly in relationships. Individuals may exhibit possessive behaviour, such as monitoring their partner’s activities, restricting their freedom, or becoming overly suspicious of their interactions with others. This often comes from fear of abandonment or insecurity, as highlighted in studies of attachment theory (Bowlby, 1969).

When jealousy becomes overwhelming, it can manifest as hostility or irritability. A person may show anger or resentment towards others for their perceived success or happiness, even if it’s irrational or unjustified. These hostile feelings can damage personal relationships and may lead to social isolation (APA, 2013).

Jealousy often leads individuals to downplay or belittle the accomplishments of others. This can be done through dismissive comments or an unwillingness to celebrate someone else’s success. By diminishing the importance of others’ achievements, jealous individuals try to protect their own sense of self-worth (Cohen & Pressman, 2015).

Jealousy can be evident in non-verbal communication. Crossed arms, tense posture, or avoiding eye contact during someone else’s success are common non-verbal signs. Research on non-verbal communication highlights how emotions like jealousy can influence body language, even when individuals attempt to conceal their feelings (Givens, 2005).

Recognising the signs of jealousy—whether in oneself or others—is crucial for addressing and resolving the underlying emotions. Understanding how jealousy manifests can help manage its impact on relationships and mental health, fostering healthier interactions.
