Construction and Validation of the Moral Inclusion/Exclusion of Other Groups (MIEG) Scale

  • Stefano PassiniEmail author

Moral exclusion is defined as viewing others as lying beyond the boundary within which moral values and rules of justice apply. In contrast, the process of moral inclusion involves the extension of social justice to several social groups. Thus, both moral inclusion and exclusion are a pivotal dimension in the study of social inequalities. Although the concept of moral inclusion/exclusion has a history of more than 20 years, research still lacks accurate instruments for measuring it. In this article, a first version of a scale that measures moral inclusion/exclusion was constructed and validated. The good reliability and correlation indexes found across the samples suggest that MIEG is a good measure for tapping into moral exclusion/inclusion symptoms.
