Why People Really Cheat On Their Partners, According To Science

Cheating in relationships is a complex and often heart-wrenching issue that touches many lives. A recent study published in The Journal of Sex Research delves into the reasons behind infidelity, offering a scientific perspective on what drives individuals to betray their partners. The findings, based on a survey of 495 adults, reveal a spectrum of motivations, shedding light on the multifaceted nature of cheating.

The Primary Culprit: Lack of Love

The study highlights that the predominant reason for cheating is a perceived “lack of love.” Astonishingly, 77% of participants cited feeling unloved or unappreciated as their motivation for straying. This underscores a critical aspect of relationships: the need for ongoing emotional connection and appreciation. Relationship expert Chelsea Leigh Trescott emphasizes that cheating often stems from a person no longer feeling loved or valued by their partner, rather than simply falling out of love. This distinction is crucial for understanding the emotional void that can lead to infidelity.

Diverse Motivations Behind Infidelity

While a lack of love tops the list, the study identifies several other significant reasons why people cheat. These insights offer a deeper understanding of the various factors that can undermine relationship fidelity.

  1. Desire for Sexual Variety: Many individuals cheat because they seek a greater variety of sexual experiences. This reason is particularly prevalent among those who feel bored or neglected in their current relationship. Licensed marriage and family therapist Racine R. Henry, Ph.D., notes that the desire for new sexual encounters is often less about the partner and more about the individual’s internal dissatisfaction.
  2. Feelings of Neglect: A substantial number of respondents (70%) reported feeling neglected or unappreciated as a driving force behind their infidelity. When emotional needs are unmet, and communication breaks down, cheating can appear as an attractive, albeit destructive, solution to feeling overlooked or undervalued.
  3. Situational Factors: Situational factors, such as being under the influence of alcohol or not thinking clearly, were also commonly cited reasons for cheating. About 70% of participants mentioned that being in a compromised state led them to make impulsive decisions. Family and relationship psychotherapist Dr. Fran Walfish explains that while situational cheating can feel devastating, it doesn’t necessarily reflect a lack of love or desire to end the relationship.
  4. Boosting Self-Esteem: For 57% of individuals, cheating was a way to bolster their self-esteem. Relationship therapist Rhonda Milrad, LCSW, suggests that infidelity can be a misguided attempt to regain a sense of personal worth or power, often rooted in deeper insecurities about one’s career, appearance, or past experiences.
  5. Acts of Anger: Cheating as an act of retaliation or out of anger was a motivation for 43% of participants. This behavior typically arises from unresolved conflicts or feelings of hurt, where infidelity is seen as a way to exact revenge or express frustration.
  6. Lack of Attachment: A significant number of people (41%) cheated because they felt a low level of commitment to their partner. This detachment can stem from various factors, including personality traits that make sustained commitment challenging.
  7. Physical Desire: Finally, about a third of the survey respondents admitted to cheating purely for the physical act of sex. This reason is often straightforward and reflects a desire for sexual gratification outside the bounds of their primary relationship.

Gender and Personality Differences

The study also reveals intriguing gender and personality differences in the motivations for cheating. Men are more likely to cheat for reasons related to sexual variety and situational factors, whereas women often cite feelings of neglect or emotional disconnect. Furthermore, individuals with commitment issues are more prone to seek multiple sexual partners, while those who are hopeless romantics might cheat due to unmet emotional needs.

Navigating the Aftermath of Infidelity

Understanding the myriad reasons behind cheating can help those affected navigate the painful aftermath. Experts stress that being cheated on is not a reflection of one’s worth or shortcomings. Infidelity often speaks more to the cheater’s internal struggles than to the quality of the relationship itself.

As relationships evolve, maintaining open communication, fostering emotional intimacy, and addressing underlying issues proactively can help prevent the drift towards infidelity. Ultimately, love is an ongoing, dynamic process that requires effort and attention from both partners to thrive.
