Minority's behavior is termed as the behavior objecting to the institutionalized domination system which controls others' behaviors by various sanctions. In this study, minority's self-sacrificing behavior style was defined as rejecting many rewards given from the institutionalized domination system. In the experiment, minority (1 confederate) always assumed a behavior concurrent with the subject's attitude (pro-attitudinal behavior for subjects themselves), and majority (4 or 5 confederates) always took a behavior against the subject's attitude (anti-attitudinal behavior for subjects themselves). In 2×2 factorial design (minority; present or not×behavior style; self-sacrificing or not), 33 subjects were asked to decide their own behavior. Subject's pro-attitudinal behavior was predicted to increase, when minority chose the self-sacrificing behavior style, as compared with the condition where minority isn't present. On the other hand, pro-attitudinal behavior was predicted not to increase, when minority took a behavior rewarded by the institutionalized domination system. Results of the experiment supported the prediction. Moreover, subject's conflict was high both when minority was present, and when minority behaved self-sacrificingly. These results suggested that self-sacrificing minority interferred with subjects' rationalization of their behavior.
