5th ENCODE Workshop on Group Accuracy, Deliberation, and Social Influence

According to the celebrated Condorcet Jury Theorem, if we can dispose of a series of jurors who each have an independent, better than random accuracy regarding a binary issue, then the larger the group of jurors we take, the more accurate the group’s majority opinion on this issue will be. In the limit, the majority opinion will be fully reliable. This mathematical result has provided the starting point for a rich literature on the wisdom of crowds and democratic decision-making. 

In practice, however, opinions are not independent. Decision-makers are typically connected through networks of social influence, and before casting their opinion, they may deliberate collectively. When doing so, the shape of the network, the order in which they exchange information, the levels of trustworthiness attributed to them, and strategic considerations are crucial for the eventual outcome of the process. The aim of this workshop is to cast light on the role of these and other parameters in group deliberation, and their implications for group accuracy and democracy.
