title: Internal facial features are signals of personality and health.
abstract: We investigated forms of socially relevant information signalled from static images of the face. We created composite images from women scoring high and low values on personality and health dimensions and measured the accuracy of raters in discriminating high from low trait values. We also looked specifically at the information content within the internal facial features, by presenting the composite images with an occluding mask. Four of the Big Five traits were accurately discriminated on the basis of the internal facial features alone (conscientiousness was the exception), as was physical health. The addition of external features in the full-face images led to improved detection for extraversion and physical health and poorer performance on intellect/imagination (or openness). Visual appearance based on internal facial features alone can therefore accurately predict behavioural biases in the form of personality, as well as levels of physical health.
