Faces Tell Everything in a Just and Biologically Determined World: Lay Theories Behind Face Reading

The present research investigated an often presumed but rarely assessed construct named the physiognomic belief—a generic belief that various traits can be inferred from faces. Studies in Japan and the United States have demonstrated that this belief can be measured reliably and invariantly across cultures and that those having stronger beliefs make more extreme trait inferences from faces. Of note, in both countries, the physiognomic belief is positively associated with a biologically deterministic view of personality traits and a belief in a just world. These findings suggest two types of naive justifications for the physiognomic belief: faces and traits should be related because they are both manifestations of biological essences and because the world is an orderly place wherein people get faces they deserve. This highlights an understudied role of folk concepts involving faces and traits in the popularity of face-based trait inference among laypeople.
