The three chapters of this thesis explore how previous experience and mental categories shape human judgments. Chapter One provides a sampling explanation for the in-group heterogeneity effect - a tendency of people to perceive the groups they belong to as more heterogeneous than the groups to which they do not belong. It notes that because people are more likely to interact with the in-group members, they will experience more variability of the in-group than the out-group. Chapters 2 and 3 investigate how mental categories affect feature-based inferences when the category of the object, people perceive, is uncertain. In an influential paper, Anderson (1991) proposed a rational model for this task. The model proposes that the infor...
