Opposites DON’T attract! We find people who look like us more attractive, study finds

From Rooney Mara and Joaquin Phoenix to Kirsten Dunst and Jesse Plemons, celebrity couples often look alike.

But the phenomenon is not exclusive to the rich and famous – one Instagram page called @siblingsordating is dedicated to snaps of couples who look eerily similar.

Now, speed dating experiments show that we find people who look like us more attractive because we see them as “friendly and trustworthy.”

Looking like someone can create a sense of “kinship,” which can lead to more pro-social behavior and a higher chance of becoming a couple.

The study comes shortly after the new phrase “doppelbanger” was coined to refer to dating someone who bears an uncanny resemblance to you.

The new study was led by psychologists from the University of Queensland in Brisbane, Australia, and was published in the journal Evolution and human behavior.

“The results suggest that people are looking for romantic partners who are facially similar,” said lead study author Amy Zhao of the University of Queensland.

“They are seen as kinder, more understanding and more trustworthy because of a possible overlap between facial similarity and relatedness.”

Multiple studies have attempted to explain why there is attraction between people who look alike, with many attributing it to subconsciously being attracted to someone who resembles a family member.

A 2008 study by Hungarian scientists found that women are more likely to choose partners whose faces resemble their fathers, while men are also more likely to be in a relationship with a woman who resembles their mother.

Meanwhile, a 2012 French study found that some men were most attracted to images of women that had been digitally manipulated to resemble their own facial features.

For the new study, the team wanted to explore what facial features make us attractive – not just looking like us, but also having a male or female face and being perceived as “prosocial” or nice.

The psychologists recruited 682 heterosexual participants and recorded a total of 2,285 speed dating interactions in the lab.

A total of 1,188 interactions were based on participants interacting with a partner of the same ethnicity, and the remaining 1,097 interactions were with a partner of a different ethnicity.

Each interaction lasted three minutes, after which participants completed a questionnaire to rate their dating partner’s attractiveness and friendliness.

Photos of the participants were used to determine facial similarities between the pairs.

Researchers found that facial similarity influenced perceptions of attractiveness — in other words, participants who rated someone attractive often appeared to look like them.

Participants also received higher ratings of the facial attractiveness of partners of the same ethnicity, compared to those of a different ethnicity.

Interestingly, facial similarity predicted friendliness ratings even when the partner was of the same or different ethnicity than the rater.

The experts believe that similar faces are a sign of kinship – a sense of being alike and therefore of belonging and trust.

This is despite previous studies suggesting that kinship signals may reduce sexual desire due to an unconscious awareness of the ‘cost of inbreeding’.

The team thinks there is “probably a genetic basis” for what kind of faces we find attractive, and that preferences for certain facial features may have evolved as a result of fitness benefits signaled by those features.

Somewhat unsurprisingly, the team also found that facial masculinity was positively associated with men’s facial attractiveness, and negatively associated with women’s facial attractiveness.

Males were considered more attractive the more masculine they appeared (unsurprisingly, females were considered less attractive if they looked more masculine)

In other words, the more masculine a man looked, the more attractive they were generally perceived, while women were considered less attractive if they looked more masculine.

The team says previous studies in this area had “major limitations” because participants judged a series of photos or computer-generated faces.

For example, a 2002 study found that participants who faced computer game opponents who resembled them in facial appearance were more willing to trust the opponent.

“It was not clear that the findings of those studies would be generalized to real-life interactions, where people move, talk, change facial expressions, show their personality, and so on,” the team says.

They conclude, “It would be worth exploring how the objective facial features we found are associated with attractiveness may or may not also be associated with real couples here.”

If you’re dating someone who JUST looks like you, you’re in good company with celebs like Kristen Stewart and Courteney Cox

Rather than opposites attract, studies have long shown that people are more likely to date partners who are similar to them.

Celebrities around the world are proving the idea — including blonde bombshell Oscar nominee Kristen Stewart and her fiancé Dylan Meyer.

Meanwhile, Friends star Courteney Cox and her partner Snow Patrol guitarist Johnny McDaid are known for their incredibly similar face shape and bone structure and piercing blue eyes.

But the phenomenon is not exclusive to the rich and famous – one Instagram page called @siblingsordating is dedicated to snaps of couples who look eerily similar.

We may be naturally drawn to other people who are similar to us because seeing them evokes a sense of familiarity or kinship.

A 2012 study by the Institut des Sciences de l’Evolution in Montpellier, France, found that more than a third of men were most attracted to images of women that had been digitally manipulated to resemble their own facial features.

There’s also an idea that couples become increasingly similar after years together, a theory supported by a 1987 University of Michigan study that found that partners who were dissimilar at the start of a marriage had a ” degree of positive convergence’. correlated with couples’ ratings of marital quality’.

However, this idea has been debunked by a more recent study from Stanford University in 2020, published in Scientific Reports.

Researchers have compiled a database of photos of more than 500 couples taken within the first two years of their marriage and anywhere from 20 to 69 years later.

They asked volunteers to examine a photo of one person and six others, including their partner, and rank them based on similarity, performing the same task using facial recognition software.

However, they found no evidence that couples transitioned into each other with age, and concluded that the spouses’ faces often resembled each other at first.
