Summary

In this project we will investigate how groups of people reach joint decisions and judgments. Groups are often presumed to be better decision makers than individuals, yet this presumption has proved to be untenable. A multitude of factors hinder groups’ potential to make high quality decisions. In this project we will investigate some of these impeding factors, while at the same time keeping our eyes open for those factors that could potentially increase groups’ ability to reach optimal decisions.



Of particular interest to this project is judicial decision-making. This type of decision making is captivating because judicial decisions have far-reaching consequences and are made by experienced, well trained and highly motivated groups or individuals. According to many, this kind of decision making cannot be mimicked in an experimental setting and thus analysis of real judicial decisions (field/archival data) offers the perfect extension of experimental research.



In short, this project focuses on factors leading to (un)biased judicial decision making in groups. This will be examined using experimental, archival and survey data.
