Infidelity Drivers: Turkish Research Reveals Psychological Causes

Turkish Researchers Identify Unexpected Psychological Drivers of Infidelity

A team from Koç University in Istanbul has uncovered surprising psychological factors that may increase the likelihood of infidelity in romantic relationships. The findings, published in The Family Journal: Counseling and Therapy for Couples and Families, are based on a study involving 280 participants aged 18 to 30 who had been in committed relationships for more than a year.

Methodology and Background

According to the researchers, nearly half of the participants reported that at least one of their parents—most often the father—had been unfaithful.

Many learned about these incidents around age 13, a formative period for developing notions of trust, emotional security and romantic attachment.

Intergenerational Patterns

Participants who had witnessed parental infidelity demonstrated significantly stronger intentions to cheat on their partners.

Researchers interpret this as a potential intergenerational transmission of behavior: early exposure to betrayal may normalize infidelity and weaken expectations of trust within adult relationships.

Past Behavior as a Predictor

The study also found that individuals who had previously cheated were more likely to express readiness to do so again.

Notably, experiencing betrayal from a past partner did not increase the likelihood of future cheating—a result the authors say highlights the role of personal agency over past trauma.

Attachment Styles and Relationship Dynamics

Researchers identified a strong link between avoidant attachment—characterized by discomfort with emotional closeness—and higher intentions toward infidelity.

• Avoidant attachment: Associated with higher infidelity intentions
• Anxious attachment: Showed no significant association with infidelity

For individuals with avoidant attachment, cheating may serve as a way to maintain emotional distance.

The Protective Role of Intimacy

High levels of emotional and sexual intimacy appeared to significantly reduce interest in extramarital affairs.

When partners feel connected and their relational needs are fulfilled, researchers say, the motivation to seek validation outside the relationship decreases.

Gender Differences

While men initially appeared more inclined toward infidelity, these differences diminished after accounting for attachment patterns, family history, and previous relationship behavior.

Key Conclusion

The study suggests that neither family history nor past mistakes predetermine a person's relationship outcomes.

Instead, the quality of intimacy and communication within a couple plays the central role in reducing the risk of infidelity and fostering long-term, trust-based relationships.
