A recent study has revealed that genetic factors may play a role in why individuals cheat on their partners.
Researchers at the State University of New York have found that sexual behaviors might be affected by the presence of a specific gene associated with alcohol consumption and gambling.
Justin Garcia, the lead researcher, discovered that an intrinsic urge for a dopamine ‘rush’ could clarify why some individuals struggle to stay monogamous.
Garcia stated, “Our findings indicate that individuals carrying a specific variant of the DRD4 gene are more inclined to have engaged in uncommitted sexual encounters, including one-night stands and acts of infidelity.”
The drive appears to originate from a pleasure and reward system, where dopamine release plays a pivotal role.
In scenarios involving uncommitted sex, the stakes are significant, the rewards substantial, and the motivations diverse – all factors contributing to a dopamine ‘rush.’
The DRD4 gene has already been associated with behaviors like alcoholism and gambling addiction, as well as other risk-taking activities.
An analysis of the DNA and sexual histories of 181 young adults revealed that those possessing the DRD4 variant were twice as likely to have experienced a one-night stand compared to those who did not have it.
According to the researchers, this study serves as the first evidence that despite desiring a committed long-term relationship, individuals may still find themselves unfaithful.
They also suggest that it is feasible to feel devoted to a partner while simultaneously engaging in infidelity.
The craving for a dopamine rush appears to function independently from the desire for commitment and romantic connections, the study indicated.
Garcia commented, “Our research does not excuse those who cheat. These relationships are associative, which means not everyone with this genetic variation will engage in one-night stands or acts of infidelity.”
“Indeed, a substantial number of individuals without this genotype also partake in one-night stands and commit infidelities. The study simply implies that a significantly higher proportion of those with this genetic variant are predisposed to these behaviors.”
He continued, “These genes do not offer an excuse, but they do shed light on how our biological makeup influences our tendencies toward a range of behaviors.”
The research team plans to conduct a similar study that examines a broader demographic of adults.
In a recent finding, scientists discovered that the DRD4 gene variant may also lead individuals to adopt more liberal perspectives.
This genetic variant drives people to pursue ‘novelty’, making them more inclined to explore unconventional political beliefs, as reported by the U.S. study.
Individuals with this gene are believed to be more receptive to others’ opinions and are influenced by them to a greater extent compared to those lacking the gene.
In the context of the U.S., this suggests that individuals with the gene are more likely to hold liberal political views.
