Although it has been widely documented that attractive political candidates often enjoy a distinct advantage at the voting booth, new research suggests that this aesthetic appeal does not change the way candidates govern once elected. A study published in the European Journal of Political Economy found that politicians who looked good were less likely to engage in rent-seeking behavior or deviate from voters’ preferences. This finding shows that transparent political systems do not allow elected officials significant leeway to act against the interests of their constituents based on appearance.
Research across multiple disciplines has demonstrated that physical attractiveness has measurable real-world benefits, a phenomenon that economists often refer to as the beauty premium. Good-looking people often have an advantage in hiring scenarios, college acceptance rates, and starting salaries across a variety of industries. This psychological bias, often referred to as the halo effect, causes people to unconsciously associate attractive looks with unrelated positive characteristics, such as high ability, great intelligence, or high moral character.
This visual bias greatly affects democratic elections. Past research has regularly demonstrated that visually appealing political candidates tend to earn more favorable first impressions and win higher vote margins. Voters who have limited information about a campaign often rely on quick judgment based solely on the candidate’s face to cast their vote.
Although the electoral benefits of beauty are widely documented, economists have little data on whether attractive looks actually correlate with politicians’ behavior once they take office. Elections typically function as a structural disciplinary mechanism. They keep leaders aligned with the public interest, with the constant threat of being voted out of office. If attractive politicians perceive that they have a built-in electoral advantage, they may feel permanently insulated from future voter punishment.
We hypothesize that, conditional on this sense of security, attractive officials may take actions that directly benefit them at the expense of voters. Such actions can include accumulating lucrative relationships with special interest groups and routinely ignoring the views of local majorities of those elected to represent them. This power relationship touches on the principal-agent problem, a concept in political economy that describes the inherent conflict in priorities between large groups of citizens and a single representative authorized to act on their behalf.
Ahmed Sukari, an economist at the University of Groningen, and his colleagues wanted to test whether this physical advantage shapes actual governance. To answer this question, Skali and a team of researchers from academic institutions in Australia, Germany, and Switzerland designed an observational analysis. They focused on the unique institutional framework of Swiss politics.
Switzerland is characterized by strict legal transparency rules and a strong system of direct democracy. This system allows social scientists to directly compare how elected officials vote with how ordinary people vote on the exact same legislative proposals. This setting provides a highly observable environment to study political loyalty without relying on vague campaign promises.
The researchers used a dataset containing official photos of 69 members of the Swiss Council of State who served from 2013 to 2014. These government portraits were highly standardized, featuring consistent camera distances, professional lighting, and identical focal lengths. The scientists intentionally did not ask Swiss citizens to rate the images to avoid statistical bias due to local popularity or pre-existing political bias.
Instead, the team recruited 147 Australian residents and asked them to rate their faces on a seven-point scale. The evaluators had no cultural ties to Swiss society and were not informed that the people in the photographs held elected office. The researchers then averaged these aesthetic scores and mathematically adjusted the numbers to account for individual differences in how harshly or leniently a given rater judged a person’s beauty.
The researchers then correlated these physical attractiveness scores with public records detailing each politician’s professional conduct. First, we looked at the total number of interest group affiliations maintained by each lawmaker. Swiss law requires immediate disclosure of all company board members, advisory roles, and organized lobbying activities, making these professional connections well known to voters.
The researchers paid particular attention to collaboration with sectoral interest groups representing narrow industries such as banking, energy production, and pharmaceuticals. These relationships are generally seen as key opportunities for rent-seeking behavior. In applied economics, rent-seeking involves attempts to increase an individual’s wealth or influence without creating new wealth in society, often through political manipulation, policy loopholes, or favorable corporate regulation.
A second measure of political behavior involves voter congruence, which assesses how well a particular leader aligns with the general public. Switzerland holds frequent referendums, where citizens vote on legal proposals with the same wording as their elected representatives. This creates a rare environment in which a particular policy decision by an official corresponds precisely with the wishes of the majority of the local constituency.
When the researchers examined the final data, they found no evidence that physical beauty predicted political behavior. Attractive legislators were not more likely to accumulate ties to special interest groups. In fact, the data showed a slight trend that better-looking politicians were less likely to affiliate with these companies, although the results were not statistically significant.
Similarly, legislators with high physical attractiveness scores were no more likely to deviate from the wishes of their constituents than those with lower physical attractiveness scores. The researchers examined whether these behavioral patterns varied depending on party alignment. They found very consistent results across left-wing, right-wing, and centrist MPs.
To ensure that other variables were not obscuring the findings, the researchers adjusted the statistical model to account for factors such as politicians’ age, gender, and education level. It also took into account the intensity of political competition that lawmakers faced during their first election cycle, including the margin of victory at the polling place. Even with these rigorous mathematical adjustments, physical attractiveness showed no measurable association with politicians’ previous comfort in office.
The authors point out that these results are closely related to the high level of transparency of the Swiss federal government. Because roll call votes are publicly recorded and lobbying affiliations must be legally disclosed, the system leaves little room for hidden organized conduct. In a political environment with weak oversight, attractive advantages can still isolate manipulative politicians who are willing to act poorly without facing the wrath of voters.
Additionally, only still photographs of faces were used in the current analysis. First impressions in the real world also include body language, physical fitness, and tone of voice, which can introduce entirely different psychological variables. This study captures a snapshot in time, rather than tracking how public perceptions of politicians change dynamically over multi-year parliamentary terms.
Future research could examine whether political parties strategically use their most attractive members for tasks beyond standard parliamentary voting duties. Good-looking officials are likely to appear more frequently in the media, give frequent television interviews, and be assigned to high-profile company committees. Researchers could also examine patterns of behavior in countries with high levels of institutional corruption or unreliable mechanisms of democratic accountability.
Another avenue for future research includes asking under what conditions beauty premiums turn into social penalties. In some professional settings, overwhelming physical attractiveness can lead to envy and intense frustration, which can lead to social friction. Identifying these invisible boundaries can help sociologists better understand how appearance shapes human hierarchies in different political and social scenarios.
The study, “A Beauty Premium in Politics? Perceptions and Political Behavior,” was authored by Ahmed Sukari, Steve Bickley, Ho Fai Chan, David Stadelman, Benno Torgler, and Stephen White.
