Both kindness and physical attractiveness are poorly defined characteristics, and anyway are not the only possible positive traits someone can have. Humor, loyalty, and work ethic are other potential traits. I’m not sure what “studies” you mean, but the applicability of animal mating behaviors to people is pretty bad for a lot of reasons. The range of behaviors is incredibly varied, from straight sperm competition, to being able to beat another animal in a fight, to gift giving, to singing, and so on. Even if women were solely interested in how their partner would help their reproductive chances (they aren’t), humans are also massive outliers in terms of how much effort we spend on our kids so “is loyal and a good parent” is way more important than physical attractiveness.
