Trust in me: trustworthy others are seen as more physically similar to the self.
The face is easily the most recognizable part of the body and the most important for social interaction (Farmer & Tsakiris, 2012). Facial appearance is often used as a guide to personality traits such as trustworthiness (Todorov, 2008). Recent studies have demonstrated that, in addition to objective characteristics such as the resemblance of the structure of a face to positive and negative emotional expressions, subjective characteristics such as the similarity of another person’s face to one’s own also influence people’s judgments about a person’s character (Bailenson, Iyengar, Yee, & Collins, 2008; DeBruine, 2002, 2005).
