Research

My aim is to understand the cognitive processes that underlie human thinking in the face of uncertainty. I address questions such as: How do we judge and decide in the face of uncertainty? What determines our degree of belief in generalizations? How do we revise our beliefs? Are we rational? My approach is to experimentally test mathematical models of such activities. A current objective is to apply knowledge from the domain of categorization to that of judgment and decision making.
