Denise Lewin Loyd studies the impact of diversity in groups. Specifically, she examines the way group composition affects the cognition, feelings, and behavior of individuals. She is particularly interested in how one's numerical representation and social status in a group interact to affect outcomes such as judgment, influence, and information sharing. Her work explores the relationship between members of the minority and majority as well as relationships within these sub-groups. A recent project examines the joint impact of status and distinctiveness (or being in the numerical minority) in evaluative groups on an individual's judgment of a similar other. Another project looks at the experience of being one of only two members of a category within a group in contrast to being the only one.
