This study examined the sense of minority and majority that is defined, not by the number of members but by cognition of social power. In Experiment 1, to test the effects of entering, 54 participants were assigned to 18 sub-groups and then half of the sub-groups were assigned as pre-existing-groups and the rest as entering-groups. The 18 sub-groups made decisions within each sub-group. Entering-groups then joined the pre-existing-groups and the resulting 6 members-groups were engaged in the same task again. Experiment 1 showed that existing-groups had the sense of minority. In Experiment 2, to test the effects of pre-evaluation, another 54 participants were allocated to 18 sub-groups and then half were given high evaluations and others were given low evaluations during decision making as in experiment 1. Each high and low evaluated sub-group was then mingled into 9 groups to make new decisions. As a result, the high-evaluated sub-groups had the sense of majority and estimated their efficiency higher than the low-evaluated sub-groups. Entering and pre-evaluation factor had no effect on the behavioral index (number of remarks and opinion acceptance). These results suggest that there is a relationship between the sense of minority and majority and group identity.
