This paper begins by replicating the Libby and Blashfield (1978) experiment for the business failure task. The investigation is then extended to consider a non–unit weighted decision scheme modelling differential task expertise among group members. In this case, the results of the study suggest that the use of groups with more than three members can be justified.
