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 and these inferences can influence people's behavior and decisions. For example, in a recent paper, my colleagues and I found that attractive Airbnb hosts charge higher prices for similar apartments, which suggests that the attractiveness of hosts guides people's apartment preferences.

Even though trait inferences from faces are often incorrect, their effects on decisions are widespread. I study why 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 in fact reflected in their facial appearance. How convinced a person is that they can read personality from faces predicts how much that person relies on first impressions when making decisions. On the other hand, my work also suggests that there is a second explanation: relying on first impressions is easy. Because first impressions are automatically accessible, relying on them to make decisions takes less cognitive effort than relying on other information.
