The Statistics on Cheating aren’t Pretty
You don’t understand why he cheated on you. You keep yourself up. You’re fun. You have a good job. You’re smart. You’re attentive to him. You may even be the mother of his child. So why?
You don’t understand why she cheated on you. You’re a kind man. You’re gainfully employed. You pay attention to her. You’re fun. You give her compliments. You’re smart. So why?
Most committed partners, both married and unmarried, don’t plan on having an affair. No one looks into their new spouse’s eyes on their wedding day thinking, ‘I’m going to tear your heart to shreds one day.’ If you’re in a long-term relationship and have never even been tempted, you may think you’re safe from slipping up. But it happens. A lot. According to facts and statistics about infidelity:
30-60% of all married people in the United States cheat at some point in their marriages.
Not only that,
2% to 3% of all children are the product of infidelity.
Especially if your partner is a serial cheater, you may wonder if it’s programmed into their DNA. Well, you may not be far off.
DNA Study Connects Cheating to Genetics
Brendan Zietsch, an Australian psychologist, set out to answer the question of whether genetics can predispose someone to cheating. In other words, is the likelihood of cheating programmed into someone’s DNA? Zietsch analyzed data from 7,378 Finnish study participants: some were siblings, while some were twins. The one factor they all had in common is they had been in a monogamous relationship for at least one year.
Why use twins? Twins, both fraternal and identical, are often used to help scientists determine whether or not a trait is inheritable. Identical twins are especially useful in this case, since their DNA is 100% the same. So if there are differences, it can be assumed that they are due to environmental factors (Kim). The study’s findings were published in early 2015 in the scientific journal Evolution and Human Behavior.
Study Conclusions about DNA, Genetics & Cheating
In a nutshell:
- 8% of men admitted to having more than one sexual partner in the last year.
- 4% of women admitted to having more than one sexual partner in the last year.
- Identical twins (both men and women) showed similar cheating or non-cheating data, whereas fraternal twins and regular siblings did not.
Zietsch concludes from his research that: ‘an individual’s genetic makeup in general influences how likely he or she is to cheat’ (Kim). There is not a single ‘cheating gene’ in the DNA, but rather that genetic variations affect our hormone levels. These levels determine how bonded to our partner we feel.
Other Points of View about DNA and Cheating
As you can imagine, this study raised skepticism. In a Washington Post article about this topic, marriage therapist Christian Jordal said about this study, ‘[why people cheat is] the same sort of mystery of the human heart: How is it that we choose to be attracted to someone? In the same way . . . we don’t have [all] the answers around infidelity issues.’
Commentator Eric Metaxas, writing for the Christian website Breakpoint says of the study’s conclusions: ‘…this view of human behavior demeans the human person, reducing us to amoral automatons doomed to act only according to our genetic software.’
The Bottom Line
So what does all this mean? It means that as genetic science gets more and more sophisticated, more studies may (or may not!) corroborate the infidelity findings of the Zietsch study. For sure, the scientific community doesn’t have all the answers yet. And even if there is a genetic component that makes cheating more likely, in our opinion, acting on the urge to cheat is always a choice, right? So if you cheat, you probably can’t get away with that age-old excuse: “My DNA made me do it!”
Of particular concern to us as a top paternity test company is that 2-3% of all American children are products of infidelity. There is a variety of important reasons why these children should know who their biological father is, and that knowledge can also strengthen families in the long run.

I think we need to pay attention to something other than this. Because if ypu believe this; of course it is true. If you don’t than it won’t be true.. What you believe you give life too.

Do the length of the alleles stay the same as you age if you have the gene? I read that people with schizophrenia have specific alleles that change in length at a certain age… Could this not be the same? Is it possible that 40 year old men are wired to cheat before their sperm stop being as viable, kind of like a last ditch effort with a biological imperative?
