A study was conducted in which 40 four-person groups were assigned a leader and made a decision. The assigned leader used a directive style and argued for a specific decision during discussion. In addition, information was distributed to group members to create full information and hidden profile conditions. Both information distribution and leader decision were found to affect group decisions, individual postdiscussion decisions, and group members' perceptions of conflict, confidence in the group decision, and compliance with the leader. Implications for information sampling and groupthink research were discussed.
