| Abstract: | The impact of information on aggregate decision is directly related to the number of members of the aggregate who know the information prior to the group decision. This experiment obtains this common knowledge effect in small group choice. Group discussion affects group choice in some cases, signaled by group choices that "overturn" the choice of a majority of the group members. In those overturned majorities, moreover, the group tended to choose the correct option, leading group choices to be more accurate than member choices. |
