Aggregation of expert opinions
Con icts of interest arise between a decision maker and agents who have information pertinent to the problem because of di erences in their preferences over outcomes. We investigate how the decision maker can extract the information by distorting the decisions that will be taken. We show that only slight distortions will be necessary when agents' signals are sufciently accurate or when the numb...

This however raises questions regarding how opinions from multiple experts can be used in a BN. Linear pooling is a popular method for combining probability assessments from multiple experts. In particular, Prior Linear Pooling (PrLP), which pools opinions and then places them into the BN, i...
