New research suggests that how attractive a candidate appears on campaign posters can influence voter behavior. Experts say this “halo effect” happens when people unconsciously associate beauty with competence and warmth—but it can be resisted with awareness and information.
Looks Still Matter in Local Politics
With Denmark’s local elections approaching, many voters are still unsure where to place their vote. Researchers warn that the smiling faces on campaign posters can subtly sway decisions, especially when voters know little about the candidates. Studies from the University of Copenhagen and Aarhus University show that candidates seen as attractive tend to receive more votes than less photogenic rivals.
When information about a candidate is limited, people naturally rely on visual cues. Psychologists describe this as a human shortcut for quick decisions. Even though beauty ideals can differ from person to person, researchers have found that people often agree on what looks pleasant or trustworthy. Average, well-balanced faces tend to be rated more attractive.
Beyond the Beauty Factor
Interestingly, it is not only “good looks” that attract votes. Some studies indicate that candidates whose appearance signals competence rather than beauty perform even better. However, this is tricky to separate, because people often assume that attractive individuals also possess other positive traits, such as intelligence or reliability. This is known as the halo effect—where one favorable characteristic influences the perception of unrelated qualities.
Facial features also shape how voters judge personality. For instance, candidates with round, childlike features—sometimes described as “baby faces”—might be seen as kind but less decisive. In contrast, older or sharper features often evoke perceptions of authority and competence. Such impressions can help or hurt, depending on a voter’s personal or political expectations.
Ideology Plays a Role Too
Across the political spectrum, physical appearance can send subtle but influential messages. Research shows that right-leaning voters are more drawn to candidates with masculine, dominant, or strong-looking faces. These traits signal decisiveness and control, qualities that appeal to conservative ideals. On the other hand, left-leaning voters tend to favor candidates who appear empathetic, warm, and approachable.
As a result, candidates may unconsciously present themselves in ways that align with their party’s perceived values. For example, a conservative candidate might use a stern or assertive photo for campaign posters, while a progressive candidate might prefer one showing friendliness and openness.
When Looking Different Can Be an Advantage
Not every politician strives for a perfect image. For members of smaller or protest parties, standing out visually can become an asset. A look that breaks traditional beauty standards can underline a party’s outsider image, signaling independence from the mainstream political elite. Some candidates even use this contrast as a deliberate strategy to connect with voters tired of “polished” politics.
On the other hand, established politicians often prefer maintaining a carefully controlled image. They rely on familiar cues such as confidence, professionalism, and warmth because these visual messages align with voter expectations and help maintain trust.
How to Avoid the Halo Effect
Fortunately, voters can limit the impact of visual bias. Knowing more about each candidate—beyond posters or photos—reduces the power of appearance-based judgments. Studies suggest that once voters take time to learn about a candidate’s positions or past work, the influence of looks fades. One effective approach is using online candidate tests that match personal values and policy priorities. These tools allow voters to focus on actual issues rather than first impressions.
Even though appearances can unconsciously shape how people vote, being aware of this tendency can help ensure decisions are based on substance. In a close race like Denmark’s local elections, even small visual biases can make a difference. Recognizing these biases is an important step toward more thoughtful and informed democratic participation.
