The most prominent method to interpret modern law is teleological. It assumes that legal rules serve a discernible purpose. We focus on one frequent purpose: the law helps the citizens overcome a dilemma. Illustrations comprise the environment, privacy, innovation, or competition. One line of our research aims at reconstructing such policy problems, and testing to which degree legal intervention is a precondition for solving them. A second line of research investigates in which ways and how successful legal rules change the behavior of the law's subjects. The third line aims at understanding the process in which new rules are made, and existing rules are applied.

The group's work focuses on the underlying cognitive and motivational aspects involved in decisions in an economic context. Our research aims at investigating information search and integration in a wide range of situations involving interdependent and strategic decision making. To this end we bring together insights from psychology and economics.
This Research Group is dedicated to investigate the psychological processes of bystander intervention against norm violations, also termed moral courage (Zivilcourage). Research approaches from personality and social psychology are combined to understand dispositional and situational determinants of intervention. Empirical strategies involve, but are not limited to, observation studies in the lab, comparisons of extreme groups (exemplars), ambulatory assessment methods, and multi-method assessment.
