A new Canadian study suggests that comparing your partner or spouse to someone else’s companion can have significant consequences for your relationship.

When Julie compares her husband George to her friend’s husband Sam, she can’t help but notice that Sam is better at helping his children with homework. But rather than be upset about George’s shortcomings in the children’s homework arena, Julie reasons that since she enjoys doing homework with their children, it’s not that important that George do it.

Julie’s reconciliation protects her partner (and their relationship!) from the negative implications of her own comparison. But not all members of a couple engage in these justifying explanations of their partner’s behaviors or characteristics.

Emerging research suggests that whether or not someone protects a partner from the negative implications of comparisons depends on the degree to which they view themselves and their partner as one unit. This phenomenon is termed the “self-other overlap.”

“People who are high on self-other overlap will attempt to protect their partner and minimize the threat by rating the trait or skill that they compared their partner on as less important,” said University of Toronto psychology Ph.D. candidate Sabrina Thai.

“Furthermore, these people are able to maintain positive views of their partner in spite of unfavorable comparisons. They still see their partner as being close to their ideal partner, which has positive implications on their relationship.”

The study is published in the Personality and Social Psychology Bulletin and co-written by Toronto psychology professor Dr. Penelope Lockwood.

“Our studies provide the first evidence that people do compare their partner to others with significant consequences for the relationship,” said Thai.

“People who are low in self-partner overlap have difficulty maintaining positive partner perceptions following threatening comparisons of their partner to others. This may be a key source of stress and conflict in people’s relationships.

“Moreover, by highlighting the benefits of high self-partner overlap, this research may identify a possible future intervention technique. Perhaps temporarily boosting someone’s perceptions of self-partner overlap may help them cope with and overcome the negative outcomes of comparing their partner.”
