If you’ve got a panty-dropping weakness or can’t seem to keep it in your pants, a gene variant linked with thrill-seeking behavior could be responsible for promiscuous behavior, among other things.
Researchers have interviewed a whole bunch of hos, and discovered variant of a dopamine receptor gene called DRD4 may predispose a person to behaviors like cheating and hitting it and quitting it. Previous studies have linked the presence of the gene variant to all kinds of fun things like boozing it up, gambling and even watching totally awesome horror movies- as well as being politically liberal.
A new study collected data and DNA from 181 young adults (and collecting DNA from the DRD4 people was probably way more fun, amirite?) and analyzed it. One researcher who worked on the study explains:
“What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity,” study researcher Justin Garcia, a postdoctoral fellow at Binghamton University, State University of New York, said in a statement.
“The motivation seems to stem from a system of pleasure and reward, which is where the release of dopamine comes in,” Garcia said. “In cases of uncommitted sex, the risks are high, the rewards substantial and the motivation variable — all elements that ensure a dopamine ‘rush.'”
The study indicated that those with the gene variant were twice as likely to commit acts of infidelity. However, Garcia cautions that it doesn’t “let transgressors off the hook,” and that the relationship between the gene and those behaviors is “associative.”
