Voters often use visual cues such as facial appearance when forming impressions of political candidates. Originally, psychological research on appearance-based politics focused on understanding whether or not these facial cues were consequential for political judgments. As this sub-field of study has expanded, the focus has shifted to understanding how and what facial cues voters utilize in their decision-making. From this perspective, inferences about political candidates are characterized by a number of interrelated appearance-based cues such as facial competence, physical attractiveness, and ingrained gender stereotypes that manifest in politicians' appearance. Importantly, this expanded research focus now includes a broader range of evaluative judgments that are inf luenced by candidates' facial appearance. Here, we provide an overview of the research on the use of appearance-based cues in political decision-making including initial information gathered about candidates, the evaluation of candidates' potential to be effective leaders, and the decision of whether or not to support candidates in an election.
