My research interests have always centered on a question I first asked myself when I was about 12 years old: Why is it that humans, who have the capacity to reason so well, often reason so poorly? Good reasoning depends on many things including: (1) acquiring useful information, (2) accessing the information, (3) adapting what you know to novel situations, and (4) understanding the causes of events. Thus, my research spans topics in both thinking and memory and in both cognitive and social psychology. Recently, I have also become interested in applying this research to issues in the legal system and in decision making generally.
