Decision research and strategy classification

Judgment and decision research studies how people decide between multiple alternatives (e.g., between different products). Psychological theories make different assumptions about which information people consider in their decisions. In our research, we develop statistical methods to test and compare such different theories against each other. Furthermore, we use these methods to investigate substantive questions about decision behavior.
