Whether your roommate is Samantha Sleeps-Around or Paul the Prude, cut him or her some slack: People's predilections for promiscuity lie partially in their DNA, according to a new study.

A particular version of a dopamine receptor gene called DRD4 is linked to people's tendency toward both infidelity and uncommitted one-night stands, the researchers reported Nov. 30 in the online open-access journal PloS One.

The same gene has already been linked to alcoholism and gambling addiction, as well as less destructive thrills like a love of horror films. One study linked the gene to an openness to new social situations, which in turn correlated with political liberalism.

In the new study, researchers gathered a detailed history of sexual behavior and relationships from 181 young adults. They also collected DNA samples from the volunteers' cheeks and analyzed the samples for the presence of the thrill-seeking version of DRD4.

"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.'"

People with the thrill-seeking gene variant were about twice as likely to report a history of one-night stands as those without the gene variant. Half of those with a love of risk imprinted in their DNA reported committing infidelity in the past, compared with 22 percent of those without the variant.

"The study doesn't let transgressors off the hook," said Garcia. "These relationships are associative, which means that not everyone with this genotype will have one-night stands or commit infidelity. Indeed, many people without this genotype still have one-night stands and commit infidelity. The study merely suggests that a much higher proportion of those with this genetic type are likely to engage in these behaviors."

Once again, Liberals have been proven to be better than Conservatives.

Lioberalism is a choice, not something you're born with! Case in point, Cenk has been a liberal for 7 years out of 41.

I assume this means liberals are sluttier, and that is a fact.

I CERTAINLY HAVE HEAPS OF DRD4

[DracoPilamZ]

Libertarians unite!

@SQuiRR3LM0nk3y "Behaviour [sic] creates the ideology, not the other way around." (?) No - people's ideas can influence their behavior. Genes and environment provide influences on what ideas we will be prone to adopting - the ideas we haven't aren't non-biological. Ideas are part of our form of life. A one-way kind of causality like that seems rather unlike the kind of chaotic systems that human beings are.

[godlessyurifan]

The correlation to progressivism might be less than the promiscuity angle. There are quite a few conservative "family values" politicians and evangelical spokesmen who've been in a few sex scandals. Plus there have been other studies that have said that liberals and conservatives are having the same amount of sex (at least in the younger generation). Maybe there's a gene for being conservative and fooling around.

@slyfox3333 YOUR FACE IS FALSE!!!! UUHHHHHH!!!

[TheManMostMysterious]

@nongo I had no idea that Cenk was 41. I always thought he was younger

[computerjero]

181 test subjects ? what a statistical joke…

[slyfox3333]

@Killzoneguy117  False

[fivegirlsonevase]

@Plato86 im just saying 'plato' that beyond your little nose are places where sexuality does not influence politics, so a wider range of people are comfortable with being conservative
