title: Discussion and Decision: The Interrelationship between Initial Preference Distribution and Group Discussion Content.
abstract: Data from an earlier published study were used to test the social decision scheme (SDS) proposition that initial distribution of preferences within a group influences the nature of subsequent discussion. Four-person groups confronted with a three-option decision task began discussion with an initial plurality, majority, or unanimity. We found that the prediscussion distribution of preferences was predictive of eventual group choice; plurality groups introduced the greatest number of facts, followed by majority, and then unanimity; minute-by-minute patterns of discussion were very different across the three initial distributions; dominant factions contributed the most to discussion; and under initial plurality, one minority preference was discussed significantly more heavily than the other. Discussion focuses on the possible role of preference orders in group decision-making processes and on possible explanations for why groups with different intitial preference distributions show different discussion patterns across time.
