“Mate poaching” means that you take a partner from another person. A man who seduces (what an old-fashioned word, neh?) a woman, someone who already has a committed relationship with another man, has poached.

It works both ways, of course.

One large 2004 study estimated that 63% of men and 54% of women are in their current relationship because their current mate poached them from their previous partner.[1] That tells us that women are just as likely-perhaps a bit more likely-to poach an attractive man as men are likely to try to steal a woman they find intriguing.

A new study by Joshua Foster and associates[2] finds that men or women who have been poached are less committed and less happy in their new relationship. They are much more likely to cheat and be looking for better partners, in spite of appearing to be committed to their current situation. If you steal a mate, your prey seems likely to keep looking, instead of enjoying the current relationship.

Foster also found that the new partner became less happy over time. His survey covered partnerships in poached and non-poached conditions. They interviewed the couples six times over a tend week span, and they found that the poached individuals became progressively more disconnected and continued to cheat on their current partner.

It seems that if you were poached, you are still in the market for the next new thing. You are still unhappy.

I suppose that says “you should not poach if you want a happy relationship.”

But look a bit deeper.

While Lord Acton famously quipped “Power corrupts and absolute power corrupts absolutely,” someone once replied, “No, it is that power attracts corruptible people.”

I imagine that people who end up being poached were giving off subtle cues that say “I am available.” They are not good at fidelity. They haven’t practiced making decisions with the frontal lobes, and instead let their limbic system, the emotional brain, guide their behavior. They see rules about loyalty and fidelity as robbing them of happiness. If their current partner were better, they suppose, then they wouldn’t have to cheat to be happy.

The word itself conjures up images of disgusting people spotlighting and shooting deer. Poach means taking a prey illegally. But is the man or woman who gets poached a prey, or rather an eager participant? Perhaps the so-called prey in this situation is equally guilty? Perhaps their rationale is “My current mate fails me. I am justified?”

A simple thought experiment: Two men are married. One to a beautiful model, and another to a rather plain woman. Both men are equally attractive. Does it shock us when the one married to the beautiful model cheats? Only if we are terribly naïve. A famous model once endured public humiliation. Her husband was caught cheating on her. We were watching a TV program, and the commentator wondered out loud, how anyone could cheat on such a beautiful woman? My son snorted derisively. “What, like plain women deserve to be cheated upon? That is pretty stupid!”

(Yes, I am bragging about my son.)

If we extend a “pass” to the man married to a plain woman, we are saying that it is her fault that her husband cheated. She just isn’t attractive enough.

But that isn’t true at all. Fidelity is a decision, not a reaction. Perhaps the man married to the plain woman simply has a higher standard that he holds himself to? Perhaps his ethics make it impossible, or at least extremely unlikely for him to cheat? (If he does cheat, under any conditions, he wasn’t really committed to his ethics.)

Am I letting the poacher off the hook? Not at all. I just think that Foster seems to put much more emphasis on the poacher. I take that as an error, ethical obliviousness. As they say, “You can’t cheat an honest man.” We think that the poacher is worthy of blame since he or she stole someone who was already committed. There is truth there. But again, look deeper.

Can we say that the cheater and the poacher deserve each other? Can we argue that neither deserves a higher quality of relationship, because they aren’t willing to make the commitment? Can we suppose that what the cheater or the poacher would call the intolerable sacrifice that fidelity demands is instead a wise decision that yields far greater happiness and security?

Can we say, “Frontal lobes rule!”?

I think so. Duty and loyalty yield happiness and joy. The Golden Rule still works.

    Frontal lobes may rule unless one has a traumatic brain injury fostering/causing impulsivenes to rule. Thus, if tempted and impulsiveness is the norm, one just might choose to jump on another relationship.

      I saw a study recently that chronic marijuana use can impair frontal lobes. That leads to some interesting thoughts.

    I concur totally with your assessment. I would add that betrayal is the opposite pole of loyalty, and anyway you slice it, betrayal hurts, especially betrayal of the self.

    Perhaps the need to diversify the gene pool with serial monogamy is still a greater temptation than we are civilized to believe? If poaching continues to increase, will the ability of humans to survive in groups be lessened? Not much of a vote for survival. With today’s population, I doubt we need gene pool diversity so I vote for fidelity, loyalty and the higher order gain of happiness.

    Interesting study. It mirrors other studies that more generally looked examine the happiness of people who contemplate divorce and then act upon it, versus those who contemplate divorce and remain married. No surprise, most of those who stay married are, when examined several years later, happier than those who divorced.

    Of course this may be somewhat of a different study if it was looking at two groups of people, both groups being those that are divorced but one as the result of “poaching” one the result of “DAU” (divorce as usual). That’s really the key question: does establishing a new marital relationship due to infidelity lead to greater unhappiness than establishing a new relationship due to other reasons?

    The bottom line, however, is that poaching is illegal. Clearly we need to have game wardens on patrol for this sort of thing. Bring in the miscreants for mandatory counseling and rehabilitation. I see the potential for a new federally funded income for therapists.

    Isn’t it great when you see your kids got the important stuff? Congratulations, Lynn. It doesn’t get better than that, does it?

      Yes, it doesn’t get better.

    I once thought that Carmen, in Bizet’s opera,could have been much more sensible and not gotten herself stabbed to death by her jealous lover. I would be more sensible. Then it occurred to me that perhaps Carmen (and others like her) preferred their choices of lifestyle and manner of death. It takes all kinds I guess….

      Wise, and witty at the same time! Thanks.
