Objective. In this article we show that physical attractiveness matters as a heuristic device for uninformed voters but not for politically savvy voters. Methods. Drawing on a two-step experiment, we first ask over 100 students to rank the physical attractiveness of candidates to the U.S. House of Representatives. Second, we create a treatment and a control group comprising each of 1,200 research different subjects. We ask the first group to indicate their vote choice by merely looking at the picture of candidates for the 2008 U.S. House of Representatives elections, while the second group has a picture and a detailed description of the political/professional competence of the contenders at their disposal. Results. We find that our first group of study subjects representing all those voters who are politically uninformed tend to cast their ballot for the better-looking candidate, whereas the second group, representing politically knowledgeable individuals, choose the more competent candidate. Conclusion. Our experimental study provides evidence that uninformed or politically unknowledgeable voters use political appearance as a heuristic device in casing their ballot at elections.The axiom "what is beautiful is good" applies to many social settings (Dion, Berscheid, and Walster, 1972:285). In human interactions, attractive individuals are immediately perceived as being more likeable and friendly (cf. Brewer and Archer, 2007). At the workplace, more attractive individuals gain a pay premium of up to 10 percent and are prone to advance their careers faster than less attractive employees (Hamermesh and Biddle, 1994). In politics, good-looking politicians are more likely to be nominated to executive positions at all levels in comparison to politicians who are perceived as less attractive (Ibrocheva, 2009). In elections, attractive candidates frequently get a vote premium of several percentage points solely based on their looks (Tsafati, Elfassi, and Weismiel-Manor, 2010;Hoegg and Lewis, 2011). But who are the voters for whom the physical appearance of candidates is a primary criterion in their votechoice? While some studies (e.g., Lenz and Lawson, 2011) entertain the possibility that uninformed voters use physical appearance as a heuristic device to make their vote choices, there is still some need for a study that empirically tests the relationship between physical attractiveness and vote choice in the presence of voters with low and high levels of information.To investigate whether uninformed individuals use physical attractiveness as an information shortcut more so than informed voters, we perform a two-step experiment. We first ask approximately 100 Canadian coders to rate the physical attractiveness of all contenders in more than 320 electoral contests for the 2008 congressional elections to the * Direct correspondence to Daniel Stockemer, School of Political Studies, University of Ottawa, 120 University (7076), Ottawa, K1N 6N5 daniel.stockemer@uottawa.ca .
