The study found that people are more attracted to faces that reflect personality traits they desire in a partner. This means that if someone wants a partner who is kind, they are more likely to find faces that look kind more attractive. The research used composite faces to show that what people find attractive in a face is linked to the personality traits they value in a partner. This suggests that the saying "what is good is beautiful" is true – people find faces beautiful if they reflect the personality traits they find good in a partner.
