The article contends that the attitudes of the majority population towards the allocation of political rights to out-group populations are distinct from attitudes towards the allocation of social rights. Data obtained from an attitudinal survey administered to a representative sample of Israeli adults show that the level of objection to the allocation of rights to labour migrants in the political sphere is twice as high as that found in the social sphere. Multivariate analysis demonstrates that attitudes towards the granting of political and social rights not only differ in the degree of objection, but are also differentially affected by the social and economic characteristics of the population. Further analysis examines the effect of perceived socio-economic threat, threat to national identity and prejudice on attitudes towards the allocation of rights. This analysis reveals that different mechanisms underlie the formation of attitudes towards the allocation of rights in the political and social arenas. The findings are discussed in light of previous research and theory.
