Is the phrase ‘once a cheater, always a cheater’ supported by research?

It’s likely you’ve heard the saying ‘once a cheater, always a cheater.’ But does research support the common phrase, or is it just something people say?

A recent study sought to answer the question by surveying men and women in committed dating relationships. They found that those who had cheated on their partner in a prior relationship were more likely to cheat again on their current partner.

In fact, 30 percent of people who had cheated before had also cheated in their current relationship, while only 13 percent of people who had never cheated before had been unfaithful to their current partner.

But that doesn’t mean all cheaters are bound to cheat again.

“The research found that among people who had been unfaithful in previous relationships, 30 percent cheated on their current partners. But that means 70 percent of those who were previously unfaithful had not cheated again. People can change,” says Dr. Brittany Lakin-Starr, a psychologist at Advocate Illinois Masonic Medical Center in Chicago.

The study also found that men were more likely than women to report physical or emotional intimacy with someone other than their partner face-to-face or online. Women with higher education were also more likely to report attraction to others online, and women whose previous partners had cheated were more likely to cheat themselves.

“There are several reasons people may cheat,” says Dr. Lakin-Starr. “First, according to evolutionary biology, humans are not hardwired to be monogamous. Second, relationships are like gardens and must be tended to, as they require time and attention to flourish. Unfortunately, with multiple demands competing for people’s attention, a partner’s needs can slowly get overlooked. For example, partners may stop complementing each other, going on dates and showing admiration. Infidelity is a symptom that these emotional needs are not being met in the relationship.  Additionally, people do not usually ‘go looking’ for an affair. On the contrary, affairs often begin as innocent friendships where the emotional attachment unexpectedly grows into something more.”

Dr. Lakin-Starr adds that people feel betrayed following infidelity because the person who was supposed to love and cherish them the most just hurt them the most.

“After someone cheats, trust is broken, and the partner who was hurt will need time and space to sort through their feelings,” says Dr. Lakin-Starr. “Research shows that partners who were cheated on often display symptoms of PTSD.”

For couples hoping to move forward and rebuild their relationship following infidelity, Dr. Lakin-Starr recommends couples therapy.

“Couples therapy, especially Gottman Couples therapy, a scientifically based approach, can help couples repair and strengthen their relationships,” says Dr. Lakin-Starr. “This particular therapy focuses on atonement, attunement (reconnecting and communicating) and attachment (redefining relationship goals, rituals and dreams) following infidelity. Therapy can help couples regain trust, look at the relationship difficulties that led up to the affair, learn how to reconnect with each other, communicate more effectively and mend their relationship.”

  2. I don’t see it as “a person changing”. If you aren’t happy in a relationship for whatever reason and you don’t have the guts to end it and actively look for something more fulfilling then that need doesn’t just go away, you are likely to cheat. Unfortunately, when the infidelity is brought to light and both parties must face what is happening then one or both parties are going to be damaged. By ignoring that need you are doing a disservice to yourself (because you aren’t acknowledging your needs nor are you truly fulfilling someone else’s needs), you are doing a disservice to your current partner (because the damage that is done by breaking someone’s trust has long lasting ramifications that will be experienced in other relationships) and you are doing your prospective partner a disservice (because she will always know that you did cheat and – depending on the security level of that person – they may actually work on that assumption that if you did it to your ex then you may do it to them). But people don’t tend to look for something that they already have, it then stands to reason that if you find what it is you are looking for then you will stop looking and that is where you see that 70% statistic come in. However, some people face a continuing change within themselves so their wants and needs often continue to change and I think that is where the 30% comes from. Its hard to find what you want if you and your needs are really changing that often.
