In a real society, individuals who do well on a task are sometimes exclusively treated from in-group members. It is because they may threaten the other in-group members' personal identity. This study examined whether such rejective attitude is constrained in the condition where the direction of intergroup comparison and sharing another category were manipulated. Seventy-six participants who are undergraduate students were asked to take a test of social intelligence and them received information about social intelligence. Using sex category as in-group, the direction of inergroup comparison was manipulated. After that, participants were received the feedback of their own point and an in-group member's point which are higher than their own point, that is, all participants were in the interpersonal upward comparison condition. At the same time, whether another category is shared with each other or not was manipulated, using arts-science category. Finally participants were asked the tendency of rejective attitude toward the comparison taget, and debriefed. Results showed that in the condition of intergroup upward comparison and unsharing another category, individuals with low trait self-esteem constrain rejective attitude, although they are less skilled at avoiding the threat to their identity. This study illustrated that the motive to maintain and/or enhance their personal and social identity affect the tendency of rejective attitude toward a superior in-group member.
