Definitions of "creepiness" tended to revolve around the theme of "differentness" as indicated by socially unacceptable or non-normative behaviours (e.g., staring, inappropriate comments, invasion of personal space), and odd physical appearance as suggested by poor hygiene, dishevelment, and general unattractiveness.
In line with Hassin and Trope's (2000) findings, participants reported gathering information from the face when making judgments of "creepiness."
The fact that facial areas not typically related to physical strength were more often associated with "creepiness" than those reliably linked to threat judgments, further suggests that there are different processes at work when one is evaluating "creepiness" versus threat or trustworthiness. It may be that "creepiness" is more an emotionally based versus physically based judgment; reliant on emotional information gathered from certain key facial features of an individual.
The present study found support for the putative association between physical attractiveness and judgments of trustworthiness (Porter et al., 2009). Physical attractiveness correlated positively and strongly with trustworthiness ratings. This fits with the stereotype that physically attractive people possess other positive attributes (e.g., intelligence, kindness), which tends to garner them preferential treatment and tangible benefits. Support was found for a negative correlation between "creepiness" and attractiveness with one of the picture groups.
