How can you tell if someone is prejudiced? By looking at the shape of his face, of course…?

Facial width to height ratio indicates high level of endorsement of prejudicial beliefs.

Facial Structure Is Indicative of Explicit Support for Prejudicial Beliefs

Can you tell whether someone has prejudicial beliefs based on their facial structure? In the last of three experiments, White and Black participants were shown pictures of White male faces and were asked to rate how prejudiced they thought each target was. Not only were pictures of targets with greater facial width-to-height ratios (fWHR) judged to be more prejudiced, but participants’ ratings of the targets correlated with the targets’ reported endorsement of prejudicial beliefs. Greater fWHR has been found to be related to higher levels of dominance and testosterone in men. It could be that men with a greater fWHR are less inhibited and are therefore more willing to report their racial prejudices.
