One Night Stands May Be Genetic 240

An anonymous reader writes "So, he or she has cheated on you for the umpteenth time and their only excuse is: 'I just can't help it.' According to researchers at Binghamton University, they may be right. The propensity for infidelity could very well be in their DNA. In a first of its kind study, a team of investigators led by Justin Garcia, a SUNY Doctoral Diversity Fellow in the laboratory of evolutionary anthropology and health at Binghamton University, State University of New York, has taken a broad look at sexual behavior, matching choices with genes and has come up with a new theory on what makes humans 'tick' when it comes to sexual activity. The biggest culprit seems to be the dopamine receptor D4 polymorphism, or DRD4 gene. Already linked to sensation-seeking behavior such as alcohol use and gambling, DRD4 is known to influence the brain's chemistry and subsequently, an individual's behavior."

    I just can't help it.

      So, he or she has cheated on you for the umpteenth time and their only excuse is: 'I just can't help it.'

      If he or she is getting anywhere near "the umpteenth time" it's not a them problem, it's a you problem. If it happens once, forgiveness is certainly acceptable. If it happens twice forgiveness starts to become questionable. If it happens a third time, what the hell are you still doing with this person? Send them packing for Christ's sake.

      Obviously this argument is based on the assumption that you have a moral objection to your significant other sleeping with other people. If not, then cheerio mate, say hello to your wife for me.

      • This is why I am divorced. I can forgive once, but any more then that shows a lack of respect for me (and our children) I now have the kids, house, and child support, and she has her new husband. All this in a state that usually shafts the man.

        • I can forgive once, but any more then that shows a lack of respect for me...

          It's not a diet, once already shows a lack of respect.

      • If it happens once, forgiveness is certainly acceptable...

        Why do so many people say that? In essence you're saying once is okay.

        I've dumped women over once. I have no regrets, I hold myself to the same standard. It's certainly not hard to adhere to unless you're actively looking.

        If they do it once, it already shows a lack of respect and you're always left wondering. Screw that. I'm not that open-minded or forgiveness oriented.

          Why do so many people say that? In essence you're saying once is okay.

          No, they're saying once is within the realm of reason to forgive someone that you really love and want to stay with.

          They aren't saying cheating once is acceptable, they are saying forgiving once is acceptable. As in, they can accept someone forgiving their SO for cheating, once. And forgiving the great disrespect that cheating shows is not easy, and is not in any way saying it's "okay".

          I've dumped women over once.... Screw that. I'm not that open-minded or forgiveness oriented.

          You might feel differently if you weren't just dumping a girlfriend, but rather divorcing a wife and mother of your kids who you fully intended to spend the rest of time with and otherwise love with all your heart.

          Or not. Maybe that's what you meant by 'dumped'. That's fine. But not everyone feels that way. Some people really do feel it's worth giving someone they love the chance to re-earn the lost trust and to show that they have changed.

          And I can readily sympathize. But once the event repeats, and they demonstrate that they aren't going to change and once again violate trust before it is even re-earned, then it becomes quite hard to justify.

    • It seems like it would be the opposite, since as a strong male with leadership traits the women would naturally flock to you, whereas a male that needs to seek out lots and lots of mates would typically be one that women wouldn't naturally be drawn to as a "good match". Of course, maybe what we're seeing there is just the natural tendency to say "yes" as a desirable man when lots of women desire it.

      Of course, you still have a damn brain, so "my genetics told me too" is never a good excuse.

      • Evolutionarily, if lots of women want to have sex with you it would be stupid to say no. Some of them will manage to raise your children, and you won't have to do any of the work! Nevermind that it's her second (more reliable) husband that actually helps raise the kid, or else he/she grows up without the benefit of a father. But all in all seems like a good deal, as long as there are enough responsible guys around to pick up the slack.

          I'm really unsurprised infidelity is a genetic thing. Is anyone? Guys who sleep around, have more kids. More kids means the same genes get spread around. I find it hard to believe anybody bothered to do a study on something so clear and logical, but I suppose even the most blatantly obvious of hypotheses need to be tested under the scientific method by somebody.

          • But I question whether those who sleep around and have more children have "better" genes. I want intelligent folks with hardy physical traits having offspring, not Cletus.

            • Depends what criteria you're applying as "better". Nature tends to assign the ability to spread and recreate a higher value than objective strength or intelligence.

              • In a habitat where welfare cheques are available, being virile and irresponsible could be considered a genetic advantage. Strength and intelligence are only advantageous if there's any real fights to win. Individuals in a zoo only need to be cute and reproductive.

                Have many surviving offspring: check.
                Have many surviving offspring reproduce: check.
                Have many surviving offspring have surviving offspring themselves: check, check and cheque.

                Anyone who doesn't impregnate any fertile female he can find isn't taking

                • We -- and this gene -- evolved in a welfare-free environment. So you might want to check your assumptions that "irresponsible virility" is only a survival trait in this "historically unique" environment, and the assumption that once the environment changes, we'd be worse off for having everyone who had at some point been on welfare in the gene pool.

          • Guys who sleep around, have more kids

            Depends. Guys who try to screw the alpha-males women tend to end up performing autofellatio after he's done with them. Group dynamics in general, and sexual dynamics in particular, tend to vary wildly between species. For instance, wolf packs only allows two individuals to mate at any one time - the "breeding pair", who are usually the leader(s) of the pack. We've observed subordinate male wolves getting their asses kicked by the entire pack after attempting to do the hanky-panky when it wasn't their tu

          See Idiocracy if you haven't. Evolution favors successful reproduction and little else.

          Setting aside the fate of the species... their are numerous species that reproduce and then die, or are killed by their mates. It would be "stupid to say no" to sex from a reproductive standpoint, but what about from a "quality of life" standpoint.

        I don't think that's what this points to, I think this merely says that genetics can cause an almost irresistible, sometimes overriding urge to do something in a certain way (or to do something at all). Of course, this then touches on a society that wants to pretend like the human brain is perfect and clearly if someone does something "wrong" or "inappropriate", it's caused by them simply not giving a fuck, and can not be influence by how their brain internally operates on a subconscious level.

      No, everything is a mixture of genetics and environment. How our genes are expressed is determined by our environment. Infidelity itself is not despicable, deceit is despicable. Not every committed relationship is monogamous.

      • And how you respond to these environments is purely genetic. The real question is what genetic determinations are more ductile to environmental influences.

        Infidelity is despicable (obviously subjective), as it is deceit. Infidelity is being unfaithful- if your contract never included sexual exclusivity then not being exclusive isn't infidelity.

          How you initially respond may be genetic, and there will always be a genetic component to your response, but culture plays a huge role. For instance, I choose to use a condom. Is choosing to use a condom genetic? It can't be, condoms are too recent for us to have evolved any sort of genetic response to them. You could say the safety/risk weighting factors are genetic, and my choice to play it safe or risky is genetic, but my specific choice to use an actual condom is cultural more than it is genetic.

    The media does not understand basic research [phdcomics.com]. In this case, we see its obsession of finding genes for behaviors; it almost never works that way.

    Genes aren't smartphone apps; you can't just say "there's a gene for that."

    Genes are more akin to code than to building blocks. A gene is more like a function than it is like a brick or mortar, and we have very little understanding of how genes interact with each other.

    I'd like to give a "bravo!" to the authors for making the paper an open-access journal article. I know that's a hard sell to publishers. The full paper [plosone.org] is available to all without registration.

    The paper itself explains the high chance that this is overblown:

    It is also important to sound several notes of caution. First, a consistent challenge in genetic association studies are that of third variable confounds, or unmeasured variables that are causally responsible for the observed finding but are associated with the measured variables thus generating a spurious association. ...

This is just a generalization of our understanding that everything in the universe has a cau

    As a male, I really like how the summary starts with "He or she has cheated". It doesn't paint infidelity as a typical male thing. I'm sick of the rosy picture in which this society paints our women. The most conservative statistics say that close to 50% of females admit to sexual infidelity [psychologytoday.com]. And yes, women are horny and have fun but not with their partner [psychologytoday.com] although in a different way from men, and yes, women frequently strike out at their partners, and not simply in self-defense; in 24% of violent American marriages, the woman is the only abuser [psychologytoday.com]. I vividly remember the Teen mom lashing out [mtv.com] episode of the MTV show Teen Mom, where she throws a few jabs and a right hook in her boyfriend's face.

    • Exactly. What makes us human is our ability to make choices that override our animal impulses. Good examples include religious fasting, dying for a cause, and extreme sports. But don't tell that to a sociologist; according to them, our environment and genes mold us into what we are and there's nothing we can do about it. Leave it to the irrational to rationalize a theory that humans can't rationalize.

    Plenty of people don't have any longterm commitment to a sexual partner, especially when they're young. Some of them have one night stands. Some are celibate between longer (than one night) term exclusive relationships. But probably most of them have one night stands. That's not infidelity.

    Nor is it genetic. One night stands are mostly determined by what the other partners want or are willing to accept from the person, not the person's own genetics.

    An interest in fidelity or infidelity might be genetic, but of course the other people have a lot do do with it.

    Once again, a very narrow set of new and interesting data about genes is exaggerated to say something wrong about broad human behavior.
