Together with Thomas Vetter I have a paper out in which we present and successfully validate statistical models of the Big Two and the Big Five personality dimensions. These models identify and visualize the facial information individuals use to make certain personality judgments. Moreover, they can be used to manipulate the respective facial information in novel faces in a natural-looking way. Thus, these models might be useful tools for researchers to study impression formation and consequences of impressions from faces on judgments and decision making in various research fields.
