Judge-Advisor Systems with Multiple Advisors (DFG Project)

Decisions and judgments are a central part of everyday life and advice helps decision-makers to make better decisions and judgments. In judge-advisor systems, the influence of advice on judgment and decision processes can be studied under different conditions. Previous research has been mainly limited to judge-advisor systems in which a single advisor gives advice to a decision-maker. In many everyday situations, decision-makers receive and seek advice from multiple advisors (the proverbial seeking of a second opinion). In this research project, we therefore investigate issues that arise specifically in the context of judge-advisor systems with multiple advisors:

• Advice taking in the presence of multiple pieces of advice
• Utilization of dependent and independent advice by decision-makers
• Differences in the utilization of aggregated vs. non-aggregated advice
