Read the theory supporting how decisions that are made by groups are better than decisions made by individuals acting alone (Michaelson, Watson, & Black, 1989). Groups bring a greater sum total of knowledge and information to the discussion of a problem, as well as a greater number of approaches and perspectives. The simulation can also demonstrate “process loss.” This phenomenon occurs when a knowledgeable group member outperforms the group, indicating that the member’s knowledge was lost sometime during the group discussion. In order for group decision making to work, unique information must be shared and absorbed by the group (Stasser, 1992). Download the complete Theoretical Background for Beyond the Valley of Kings.
