From faculty meetings and student projects to corporate boards and consulting firms, many decisions are made by groups rather than by individuals. In these settings, individuals may bring differing levels of knowledge and expertise to the table; therefore, the performance of the group depends heavily upon eliciting and acting upon the best information from the most informed individuals. Understanding how individuals make the decision of when toe volunteer information to the group is an important first step toward evaluating the efficiency of different group decision-making procedures.
