Blame It on the Brain

If you've ever blamed a cheating spouse's nether regions for his infidelities, new research has proven that his brain is actually what's to blame. Swedish scientists have found that men who carry a specific gene variant called allele — which is present in two of every five men — are more likely to experience marital problems and divorce than those who lack this particular variant of a gene. This study also states the following:

Men with two copies of the allele had twice the risk of experiencing marital dysfunction, with a threat of divorce during the last year, compared to men carrying one or no copies. Women married to men with one or two copies of the allele scored lower on average on how satisfied they were with the relationship compared to women married to men with no copies.

As you can see, infidelity is not a simple choice like so many people believe. As funny as it may sound, these findings have actually fueled a debate as to whether or not men should get tested for this gene before walking down the aisle. On the other hand, Helen Fisher, a biological anthropologist at Rutgers University feels that knowing if you have a weak link makes it easier to overcome. For instance, a man who knows he has the allele might be able to ignore the tugs of restlessness he might feel in his relationship and say, "Oh, it is just my DNA, and I am going to ignore it."

Pretty interesting information, huh! If you're single, would you want your future significant other to take a DNA test for this gene? What are your thoughts on this new finding?

I would definitely want to get my guy screened for that allele before I married.

"As you can see, infidelity is not a simple choice like so many people believe." It may not be easy, but it *IS* a choice.

I definitely think it's a choice. Yes, biologically the human race is made up of so-called cheaters. Otherwise, how could we procreate billions of years ago. BUT, I feel we have evolved enough that we have the brains to make the choice now.

they *can't* be separate from each other.

I agree with y'all that everyone (men and women) have brains and we should use them to override instincts that were developed during primal times...but... I don't think it's that easy. Genes and brains are interlinked, it's not like the two things are totally separate components of a person. So if a guy has that gene that causes cheating behavior it might not be as simple as getting him to use self control. Saying he has that gene is kind of the same thing as saying he lacks self control. Your brain if what gives you the self control, decency, common sense, etc. that y'all were talking if you have a gene that affects that stuff in your brain, it means the way you think is affected. So in other words, guys with that gene think differently than guys without it, so for ex. the guys with the gene might not have that voice in their head telling them to have self control like the other guys do. As much as we would like to think our "modern" human brains can "out think" our instincts, I don't think that's the case. Yeah in some cases we can override our instincts, but it only goes so far. Because our instincts are what influence our brains...they can be separate from each other.

I agree Shopaholichunny! Last thing I heard... we all have our own strengths and weaknesses and that has never been an excuse for failure!
Marseeah Marseeah 8 years And allele is just a pair of genes. Allele is not the name of this specific gene mutation, but just the term for what they're talking about.

:oy: Oh please. When my ex-boyfriennd cheated on me it was HIS choice not because of some damn gene in his brain. It sounds to me like it's just another excuse for men to use. :rant:
