This research was conducted to see whether there are any differences in choice shifts of group decision, between leaders who have responsibilities for a department of one organization and non-leaders who have responsibilities only for their own job behavior without additional responsibilities, in one Problem situation that the organization generally can confront. The experiment is to let the army platoon-leaders and riflemen make individual decisions and group decisions by group discussion, about the risk level of Ranger training course, under achievement-stressed condition and safety-stressed condition. As a result of study, leaders in general are riskier than non-leaders, but the choice shifts of leaders group and non-leaders group are the same both in direction and in amount. However, choice shifts are varied according to situations: in achievement-stressed condition choice shifts are remarkable but in safety-stressed condition choice shifts are not found.
