This document discusses challenges groups face in decision making and how to overcome them. It notes that groups have the potential to make more informed decisions by drawing on diverse information and perspectives from members. However, this promise is only realized if groups avoid "process loss" by overcoming problems related to composition, participation, and influence. Composition problems include oversampling similar viewpoints. Participation problems involve some members dominating discussion or remaining spectators. Influence problems relate to difficulty voicing disagreement. Process loss is best avoided by legitimizing conflict, soliciting views privately before discussion, and bringing quiet members back into participation.
