In my research, I aim to understand how people form judgments about objects, people, and categories.
In my latest projects, I study how people aggregate experiences with group members to form (1) evaluative judgments about the group as a whole and (2) perceptions of social norms within this group. In the context of evaluative judgments, we show that people seem to follow a simple averaging heuristic that leads to a systematic bias in many naturally occurring environments. Similarly, when people learn norms from their observations, these are better explained by the majority behavior than by the behavior of the majority.
In other projects, I study how generalization in exploration-exploration contexts is affected by categorization. and quantify the temporal stability of social preferences in group contexts.
