Most people believe that infidelity is a very bad thing,1 yet a majority of people admit they have cheated on a romantic partner. In fact, studies have shown that about 75 percent of men and 68 percent of women have cheated at some point in a relationship.2,3
There are many reasons why people are unfaithful to their partners, but one possibility is that cheating may seem like a more acceptable behavior for us to engage in if we think it’s commonplace and widely accepted. If we think that our own cheating is less frequent or severe than the norm, we’ll be more likely to let ourselves slide and succumb to temptation. “Everyone else is doing it, so if I have one little dalliance that wouldn’t be so bad."
We often compare ourselves to others and compare ourselves to what we believe is typical behavior. According to social comparison theory, if we want to know where we stand on a particular behavior, we compare ourselves to our peers.4 So if you want to know if your faithfulness to your partner is typical, you can compare yourself to others.
