Research interests

Most of my work focuses on first impressions and social decision-making.

People spontaneously infer a variety of traits (e.g., trustworthiness, attractiveness) from a person's facial appearance. Even though trait inferences from faces are often inaccurate, people rely on them when making many different decisions. For example, my research shows that people are willing to pay more money to stay with attractive Airbnb hosts and that attractive politicians are more likely to win elections.

Why do people rely on facial stereotypes, even when better information is available? On the one hand, my work suggests that many people believe that a person's personality is reflected in their facial appearance (i.e., people are lay physiognomists). Crucially, people who score higher on physiognomic belief rely more on first impressions. On the other hand, my work suggests a second explanation: relying on first impressions is easy. Because first impressions are intuitively accessible, relying on them takes less cognitive effort than relying on other information. I am currently using these insights to design interventions that aim at reducing reliance on first impressions.
