Post-decision consolidation in large group decision-making

• Decision-makers tend to change the psychological attractiveness of decision alternatives in favour of their own preferred alternative after the decision is made. In two experiments, the present research examined whether such decision consolidation occurs also among individual group members in a large group decision-making situation. High-school students were presented with a decision scenario on an important issue in their school. The final decision was made by in-group authority, out-group authority or by majority after a ballot voting. Results showed that individual members of large groups changed the attractiveness of their preferred alternative from a pre- to a post decision phase, that these consolidation effects increased when decisions were made by in-group members and when participants identified strongly with their school. Implications of the findings for understanding of group behavior and subgroup relations are discussed.
