7. Conclusion
Sport consumers belong to multiple groups, which influence and shape their behaviour. In this paper, we advanced on initial insights into this phenomenon through the delineation of the MIIF. The framework consists of three levels of group membership: superordinate, sub, and relational. The three levels reflect what attracts a person to identify with a group and its level of inclusiveness in relation to the superordinate identity. At the subgroup level, consumers seek out satellite, stadium sections, and contrasting subgroups for a sense of community, to self-classify, gain distinctiveness, or subjective uncertainty reduction. In relational groups, consumers are socialised into the superordinate identity, build social relationships through the superordinate or subgroup identity, and enrich consumption experiences through meaningful interpersonal attachments. Together, each of these benefits illustrate that, in addition to the superordinate identification, consumers maintain choice and flexibility over the social relationships and subgroups they use to advance their self-concept and consumption experiences.
