The Lab

Principles of Rationality Lab

Our goal is to understand the causes and consequences of rational and irrational judgment. To do this, we take a highly interdisciplinary approach that combines cognitive science and behavioral economics. We investigate a wide range of decisions using a blend of computational cognitive modeling and behavioral experiments.
