Is cheating genetic?

People with a certain ‘cheating’ gene variant are more likely to have casual sex and one-night stands – and to cheat on their partners.

It’s all down to a gene which affects how much dopamine your brain produces, according to recent research.

Dopamine junkies

People with the ‘cheating’ version of the DRD4-gene are more likely to take risks because they get a bigger dopamine pay-off, the study‘s lead author Justin Garcia told Science Daily.

Dopamine is the ‘pleasure chemical’ that makes experiences like eating food and having sex feel so good.

People without the cheating gene variant might skydive, land, and be satisfied with the experience. People with the cheating variant immediately long to do it all over again.

Thrill-seekers

Both groups have the same experience. But only the second group are thrill-seekers, driven to repeat the experience, again and again, to satisfy their cravings for dopamine.

This craving for dopamine might also explain why people with the ‘cheating’ variant of the DRD4-gene are more unfaithful to their partners even when they are wildly in love and claim to be totally committed to them.

‘I just can’t help it’

Garcia points out that the study’s results don’t let cheaters off the hook for their bad behaviour. But it can explain their motivations.

Perhaps the most provocative finding is that there may be two different biochemical systems, one which keeps you faithful the other which pushes you to be unfaithful. And they both work at the same time. So when you hear ‘I love you‘ but ‘I just couldn’t help it’ together, there may be some truth in it.

      what you say is interesting, but please don’t use this article to justify your behavior. You are still hurting your girlfriends by cheating on them. Just think what you would do if you found out they were cheating on you.

  4. It all lies with the so
    It all lies with the so called “perceptual response”(perception),you cannot cheat in the name of genetics yet self control is the most provocative item.
    Encourage not by inducing this “genes” things to the love matters coz the faithful & unfaithful will deviate from reality just to fulfill their own interests without caring their partners.

    1. Hi Major,

      Hi Major,
      well, there are always two people you need for cheating. And if one of them says no, it won’t happen. So, if you should ever find yourself in this situation again, it’s up to you to say no.

    1. Shan,

      Shan,
      it’s up to you: do you think he is truthful to you, or that he can change? And that this is the kind of relationship you want? Then go for it.
      I doubt he respects you very much, and I think you can do better. But again, it’s your choice!
      Good luck!

    1. Hi Lilian, If your partner…
      Hi Lilian, If your partner is cheating and he is not remorseful and refuses to change instead he is turning against you, you need to think about whether this is the kind of relationship you want to have. If not then it maybe time to break up. This is tough since you still love him but you have to think about what you want and then make a decision that you will be happy with. We wish you well.

      Hey Essy, It is important for partner to be committed to each other, to be clear about their expectations early in the relationship and share the same and talk openly and honestly about everything in the relationship.
