Abstract
we study the effects that identities with different levels of inclusion have on attitudes towards relevants outgroups. We start from two main assumptions. First, people have multiple identities, which can be structured hierarchically. Second, identities have a context-dependent nature. The two studies carried out showed, in support of our hypothesis, that more inclusive categories (e. g., European) are associated with less prejudice towards outgroups than less inclusive categories (e. g., Spanish). The results are discussed in the light of several categorization theories.
