ABSTRACT
Our faces convey a lot of information about our social identities. From looking at someone's face we can infer some details of their racial background and decide whether they seem old or young, male or female, attractive or unattractive, friendly or unapproachable, intelligent or unintelligent, and so on. Some of these inferences (such as age or sex) are remarkably accurate, others (such as approachability or intelligence) can turn out to be really wide of the mark, yet we all carry on making them.
