Having the right face for the job: The effect of facial width-to-height ratio on job selection preferences.

Prior research has found that various job candidate characteristics can influence hiring decisions. The current work used experimental methods to test how a novel, appearance-based cue known as a facial width-to-height ratio (fWHR) can bias hiring preferences. A first study provides evidence for our initial hypothesis: people believed high fWHR candidates would be a better fit for blue-collar jobs compared with low fWHR candidates, who were in turn favoured for white-collar jobs. A second study replicates this initial finding and extends it by demonstrating that the effect of fWHR-derived trait inferences of strength and intelligence on hireability predictably varies by job type. Finally, in a third study, we find that this bias reverses when traditional stereotypes of blue-collar and white-collar jobs requiring physicality and intellect are subverted, finding that perceptions of the fit between face type and presumed job requirements matter most for hiring preferences. Together, these findings demonstrate how a seemingly subtle appearance-based cue can have robust implications for hiring.
