Scientists have proven that people choose their «doppelgangers» as spouses.

Research has disproven the theory that opposites attract.

Back in 1987, researchers from the University of Michigan sought to determine if there was a connection between the appearance of spouses. Studying images of couples who had been married for about 25 years, they concluded that after years of living together, partners become more similar to each other. They explained this phenomenon as a result of empathetic mimicry, noting that prolonged social contact contributes to «copying» the facial expressions and features of the partner.

However, new research by scientists from Stanford University contradicts this theory.

The researchers examined images of the faces of 517 couples taken at the beginning of their marriage and again after 20 or more years of living together. The images were analyzed in three different ways: first by the researchers themselves, then they asked a group of volunteers to identify the correct pairs, and finally, the images were scanned using facial recognition technology.

All three stages yielded the same result: partners did not «adjust» to each other’s appearance during their life together. Moreover, over time, they actually became more different.


However, it was the initial images that caught the attention of scientists. It turned out that from the outset, people choose to marry partners who resemble them. The authors of the study note that in marriage, the principle of «opposites attract» does not apply; on the contrary, partners are more likely to choose someone similar, according to the article in Scientific Reports.
