The purpose of this study was to evaluate the influence of facial convexity on the perception of social attributes in a young adult population. Nine models were asked to pose for a 3 dimensional photograph that was then modified to represent ideal, retrognathic, and prognathic facial convexity angles. Survey evaluators were shown digital videos of models with ideal and non-ideal profiles and asked to rate their perception of the following 4 social attributes: intelligence, athleticism, popularity, and leadership ability using a visual analog scale. Results gathered from 271 evaluators showed that the model images with ideal facial convexity angles were rated higher on average than the same model images with retrognathic and prognathic profiles. The differences in ratings between ideal and non-ideal profiles were significant for intelligence (P = 0.0009), athleticism (P = 0.0002), and leadership ability (P = 0.0008). Differences in perceived popularity (P = 0.2169) showed no significant differences among facial convexities.
