Most real-world collective decisions start with disagreement, i.e. differences in beliefs or credences among group members. The overall research question addressed by this project is whether and how a group can choose to preserve disagreement as long as it is rational to do so (economically speaking, welfare-enhancing) and reduce disagreement when it becomes harmful. Put differently, what are the epistemic and institutional prerequisites for groups to optimally “manage” disagreement?
The project contributes to theory-building about how groups and their members should rationally respond to disagreement. Such an account will help to improve actual decision-making policies and to make them more immune against the influence of “fake news”, propaganda, and long-term polarization.
- To investigate the epistemic and institutional prerequisites for managing disagreement.
- To explore experimentally the use of normative principles in group disagreement.
- To provide a game-theoretic framework of information biases and propaganda.
