Two studies using the minimal group paradigm were conducted to investigate the intergroup discrimination in an experimentally created minority and majority groups. In both studies, subjects were divided into the minority and the majority group by drawing lots, and asked to allocate points between other ingroup members and outgroup members. In the first study, it was found that the minority group showed significant ingroup favouritism whereas the majority group did not. The minority group was more aware of their membership in the group than their counterpart. In the second study, subjects were led to believe that the minority group and the majority group had either similar or different social attitude. On the whole, both the minority and the majority group favoured a similar group and discriminated against a dissimilar group. The effects of attitudinal similarity in minimal groups were discussed.
