 Nevertheless, the causal claims made by social-model theorists are relevant to justice in several ways. First, as suggested above, for most theories of justice, the mere fact that the social environment can be modified in ways that alleviate the disadvantages associated with impairment places demands for their alleviation within the scope of justice—as claims that a theory of justice must consider and weigh. Second, the fact that those disadvantages are caused by social arrangements is relevant for those theories that regard society as having a stronger duty not to create or aggravate disadvantages than it has to prevent or correct them (Wasserman 2001, Schemmel 2012). Finally, alleviating the disadvantages attributable to prejudice or stigma will enjoy priority on any theory of justice that treats disadvantage resulting from prejudice or stigma as a greater injustice than innocently-created  disadvantage.[3]
