This paper focuses on the superordinate (national)-subgroup (ethnic) association in relation to group identifications, relative ingroup indispensability, relative ingroup prototypicality and their effects on outgroup and ingroup evaluations. Survey data were collected from a large sample of Mauritian adolescents (N = 1,784) from three ethnic groups (Hindus, Muslims, Creoles). National and dual identifiers were more positive towards the outgroups than ethnic identifiers. Furthermore, relative ingroup prototypicality and relative ingroup indispensability were empirically distinguishable constructs. The Creoles, who are of lower status, had higher scores on both these measures. Also it turned out that relative ingroup indispensability and relative ingroup prototypicality were independently associated to respectively more negative outgroup evaluation and more positive ingroup evaluation. The findings give a differentiated view of the idea that a complex representation of the superordinate category fosters outgroup acceptance.
