Infidelity is one of the most common and difficult problems to face in relationships, with profound effects on the trust and well-being of both members. Although it is socially condemned, infidelity is frequent, and its causes have been the subject of numerous studies. One of the least explored factors so far is the role of moral disengagement, a psychological trait that allows one to justify actions that go against one’s own values without feeling guilty.
Recently, A study has shown that moral disengagement is linked to the propensity to commit infidelity and lower levels of relationship satisfaction. People with this characteristic are not only more likely to cheat on their partners, but they also tend to distrust them. This discovery sheds light on how certain psychological and moral traits can influence the stability and quality of romantic relationships.
Moral disengagement, also called MD for its acronym in English, is a concept in psychology that describes the ability of some people to justify their actions even if these go against their own values or moral standards.
This ability allows people to act contrary to their principles without feeling the guilt or discomfort that would arise under normal conditions. In other words, moral disengagement allows the action to be “disconnected” from internal principles, thus ensuring that people do not feel responsible or question their decisions, even if they are socially reprehensible.
MD can manifest itself in various aspects of daily and everyday life. For example, someone justifying lying at work might rationalize it by saying that “everyone does it” or that “it’s necessary to be successful.” This type of thinking allows the person to deceive themselves and feel that their actions are not so blameworthy.
In this way, moral disengagement functions as a mechanism that protects self-esteem and psychological well-being in the short term, although it may compromise personal ethics and long-term relationships.
In the context of relationships, MD can lead a person to justify behaviors that they would normally consider immoral, such as infidelity. A person who commits to acts that his own morality condemns, such as cheating on his partner, as long as we are talking about a closed relationship or with specific limits, You can use this mechanism to reduce guilt and rationalize your decisions. Thus, MD does not eliminate a person’s moral standards, but rather allows him to deviate from them without significantly affecting his self-concept.
Understanding MD is key, as it allows you to understand how some people can cheat on their partners without feeling internally conflicted. This psychological and moral trait helps explain, at least in part, the disconnect between beliefs and actions in romantic relationships.
The relationship between moral disengagement and infidelity
A study carried out by Aignesberger and Greitemeyer explored how moral disengagement can influence couple satisfaction, the perception of infidelity, and the propensity to commit infidelity. To do this, they analyzed 236 couples (both in dating relationships and in marriages) to understand how MD manifests itself in both members of the couple and how this affects the relationship as a whole.
The researchers used the Actor-Partner Interdependence Model (APIM), which allows us to examine how a person’s characteristics (in this case, their levels of MD) not only influence their own behavior and satisfaction, but also those of their partner. This methodology is useful to understand the mutual effects within a relationship, evaluating how each person’s MD relates to both their own satisfaction and that of their partner.
To measure MD, questionnaires specifically designed to identify each participant’s tendency to justify behaviors that could be perceived as immoral were applied. Couple satisfaction was also evaluated and we inquired about what behaviors each person considered to be infidelity, in addition to asking if they had committed any type of self-defined infidelity (that is, behaviors that the person themselves consider to be infidelity).
One of the key findings was that MD levels were correlated between both members of the couple. People with high MD tended to have partners with similar attitudes suggesting that MD could influence partner choice. Furthermore, the study showed that high levels of MD were associated with lower relationship satisfaction and with a greater likelihood of committing infidelity according to each individual’s own definition, as well as with greater suspicions of infidelity in their partner.
Main effects on couple relationships
The findings of this study reveal significant information about how moral disengagement (MD) affects couple relationships, particularly in relation to relationship satisfaction and infidelity. Let’s review some of the main results:
One of the most notable results is that people with high levels of MD tend to experience lower relationship satisfaction. This means that by justifying actions that contradict their personal values, people can weaken the emotional connection with their partner, which has an impact on the well-being of the relationship. Furthermore, the study found that this effect is mutual: not only does a person’s MD affect their own satisfaction, but also that of their partner.
2. Consideration of infidelity
Another important finding is that MD does not seem to modify what people consider to be infidelity. In other words, the idea of what constitutes betrayal or deception in a partner remains the same for both high and low MD people.
However, Those with high levels of moral disengagement are more likely to engage in what they consider to be infidelity. This implies that, although they recognize that their actions could violate their moral commitment, they justify their actions in ways that minimize guilt and allow them to maintain an acceptable self-image.
3. Tendency to be suspicious
Additionally, the study showed that people high in MD have a greater tendency to suspect that their partners might cheat on them. This finding is interesting, as it suggests that moral disengagement not only influences one’s own behavior, but also the perception of one’s partner’s intentions. It is possible that, when justifying their own morally questionable actions, these people project the same type of behaviors onto their partner, which generates distrust and can fuel conflicts in the relationship.
4. Disconnection between morality and actions
This pattern of behavior suggests a disconnect between moral beliefs and actions. People high in MD do not necessarily deny that they are acting against their principles, but instead choose not to follow them when it is convenient for them. So, Moral disengagement acts as a kind of “moral damper” allowing individuals to distance themselves from their own values and norms when it is beneficial to their personal interests.
Implications and relevance
The results of this study on moral disengagement have important implications for understanding the dynamics in couple relationships. Knowing that this trait is linked to infidelity and dissatisfaction in the relationship allows us to explore new ways to address conflicts and improve communication between couples.
The MD, by facilitating the justification of actions that violate its own principles, could be a barrier to establishing deep and satisfying relationships since it breaks trust and allows each member to act according to their interests without feeling guilt.
From a therapeutic perspective, these findings suggest that working on self-awareness and the alignment between beliefs and actions could be key to improving the health of relationships. In couples therapy, exploring how each individual justifies or minimizes their morally questionable behaviors can help reduce mistrust and strengthen mutual commitment.
Furthermore, these results can also serve to educate about the importance of coherence between personal values and behavior, especially in issues of fidelity and honesty in relationships. The MD shows how certain psychological traits can put the stability of a relationship at risk and, by identifying them, couples and mental health professionals can work to build stronger and more conscious bonds. Research thus provides a valuable tool to help understand and prevent problems in coexistence and mutual trust.
In short, moral disengagement emerges as a relevant factor in couple relationships, linked to a greater predisposition to infidelity and lower levels of satisfaction. People with high MD tend to justify their immoral actions, distancing themselves from their principles without experiencing guilt. This trait not only affects your own well-being in the relationship, but also your partner’s trust and satisfaction. The findings highlight the importance of working on coherence between values and behaviors in couples therapy, promoting a more solid, honest relationship that is less vulnerable to conflicts derived from mistrust.
