Chances of infidelity are significantly higher among the more powerful, according to a new study.
Psychologists from Reichman University in Herzliya, Israel, and the University of Rochester conducted a series of experiments and discovered that power dynamics play an important role in how people feel and behave when it comes to being faithful to their spouses or significant others.
Why? Prior research has established that feeling and being perceived as powerful can make people feel more confident and entitled—and likely to act more impulsively. Previous studies have shown that those who possess relatively greater degrees of power have more potential to influence, change, or control another person, or, conversely, to resist another person’s efforts to influence them.
The new study adds to the body of existing research by applying it specifically to intimate relationships, finding that those who feel more powerful are less dependent on others, think more highly of themselves, and are more confident that others find them desirable.
“In a romantic relationship, these power dynamics might lead the more powerful partner to think they bring more to the table than their less powerful partner,” says lead author Gurit Birnbaum, a professor of psychology at Reichman University. “The more powerful might see this as a sign that they have more options outside the relationship and are more desirable partners in general.”
The researchers conducted a series of four studies to test how perceptions of relationship power influence a person’s interest in alternative partners. They recruited participants who were in monogamous, heterosexual relationships of at least four months.
In the first study, as a form of power manipulation, participants were asked to describe either a time they felt powerful vis-à-vis their current partner or a typical day in their relationship. Afterward they wrote a sexual fantasy about someone other than their partner.
In the second study, following the same power manipulation, participants looked at photos of strangers and decided under time pressure which ones, if any, they would consider as potential partners.
In the third study, participants described the power dynamics in their existing romantic relationship and rated their own perceived power and mate value compared to that of their partner. Next, participants were asked to complete a task with an attractive person, who was a study insider, and then rated their sexual desire for the insider.
In the fourth study, both partners in a relationship reported separately each day for three weeks on their perceived relationship power, their perceived value as a partner, and any sexual activities—including sexual fantasies, flirting, or having sex—with someone other than their partner.
Across the four studies, the team found that perceptions of power within a relationship significantly predicted a person’s interest in other potential mates—including sexual fantasies, desires, and real-life interactions. That is, people who perceived themselves as having more power in their relationship were more interested in others as potential partners.
“Those with a higher sense of power may feel motivated to disregard their commitment to the relationship and act on desires for short-term flings or potentially other, more novel partners if the opportunity arises,” says coauthor Harry Reis, a professor in the University of Rochester psychology department.
People who feel more powerful in their relationship tended to rate their value as a partner higher than their partner’s value, which could become destructive.
“When people feel powerful and believe they have more relationship options than their current partner, they might be more inclined to pay attention to other potentially promising alternatives,” says Reis.
“The belief in having other options, like other possible partners, can weaken their commitment to their current relationship.”
