Researchers at City University, Hong Kong, explored how couples look alike in the long run and enjoy higher marital satisfaction. The study is published in the journal PLOS ONE.
In order to study the link between relationship quality and facial similarity between couples, the research team conducted a series of experiments. They surveyed factors like facial resemblance in couples, perceived attractiveness and personality traits, how facial resemblance reveals specific information about the couples, etc.
The results revealed that facial resemblances of spouses are good markers of the quality of intimate relationships. The psychology behind this is that both intrinsic and extrinsic features contribute to the goal of looking for a similar partner—in looks, personality, etc.
The more the similarities between intimate partners/spouses, the greater the chance of the said couple enjoying happiness and marital fulfillment.
