Recent research showed that morality is the strongest basis for the positive evaluation of
the ingroup. Starting from these findings, the present study aimed to investigate whether
the perceived similarity between a subordinate and a superordinate ingroup on moralityrelated
norms promotes a dual identification with the lower- and higher-order category. The
results revealed that when participants perceived low similarity on moral norms, the positive
relation between subordinate and superordinate identification disappeared. The perceived
similarity on norms referred to other dimensions (i.e., sociability and competence) did not
affect the identification transfer to the inclusive category, showing the specific role of the
moral norms in such a process.
