Have you ever looked at a long-married couple and thought they somehow resemble each other? Maybe they have similar smiles, matching facial expressions, or even a comparable style. Many people believe that couples eventually begin to look alike after years together.
Psychology says there is some truth to this idea, but not in the way many people assume. Researchers have found that people often choose partners who already share certain characteristics with them, and living together for years can also lead to similar expressions, habits, and grooming styles. At the same time, some studies suggest our brains are naturally inclined to perceive romantic partners as more physically alike than they really are.
