People are quick to form judgments of other people's social class standing (for example, whether they are rich or poor) from very minimal information such as accent, clothing, and even facial appearance. People also associate social class standing with particular stereotypes (like that the poor are incompetent). Here, we tested what kinds of facial appearance leads to judgments of higher versus lower social class, and found that longer, narrower faces with upturned mouth corners and longer, more protruding features and lighter, warmer complexions were perceived as rich (vs shorter, wider faces with downturned mouths and shorter, flatter features and darker, cooler complexions were perceived as poor). Importantly, each of these aspects of facial appearance involved in perceptions of social class also affected perceptions of related stereotypes - for example, longer and narrower faces are also judged as competent, and faces with upturned mouths are also judged as warm and trustworthy.
