The Conversation

Everyone seems to agree that opposites attract. Young and old people, happy and distressed couples, single folks and married partners – all apparently buy the classic adage about love. Relationship experts have written books based on this assumption. It’s even been internalized by people who are on the hunt for a partner, with 86 percent of those looking for love saying they’re seeking someone with opposite traits.

The problem is that what’s true of magnets is not at all true of romance. As I explain in my book, “Great Myths of Intimate Relationships: Dating, Sex, and Marriage,” people tend to be attracted to those who are similar – not opposite – to themselves.

Whether people really find opposites more attractive has been the subject of many scientific studies. Researchers have investigated what combination makes for better romantic partners – those who are similar, different, or opposite? Scientists call these three possibilities the homogamy hypothesis, the heterogamy hypothesis and the complementarity hypothesis, respectively.

The clear winner is homogamy. Since the 1950s, social scientists have conducted over 240 studies to determine whether similarity in terms of attitudes, personality traits, outside interests, values and other characteristics leads to attraction. In 2013, psychologists Matthew Montoya and Robert Horton examined the combined results of these studies in what’s called a meta-analysis. They found an irrefutable association between being similar to and being interested in the other person.

In other words, there is clear and convincing evidence that birds of a feather flock together. For human beings, the attractiveness of similarity is so strong that it is found across cultures.

Because similarity is associated with attraction, it makes sense that individuals in committed relationships tend to be alike in many ways. Sometimes this is called assortative mating, although this term is more often used to describe the ways in which people with similar levels of educational attainment, financial means and physical appearance tend to pair up.

None of this necessarily means that opposites don’t attract. Both the homogamy hypothesis and the complementarity hypothesis could be true. So is there scientific support that opposites might attract at least some of the time?
