We examined the moderating role of national identification in understanding when a focus on intergroup similarity versus difference on ingroup stereotypical traits-manipulated with scale anchors-leads to support for discriminatory immigration policies. In line with intergroup distinctiveness research, national identification moderated the similarity-difference manipulation effect. Low national identifiers supported discriminatory immigration policies more when intergroup difference rather than similarity was made salient, whereas the opposite pattern was found for high national identifiers: They trended toward being more discriminatory when similarity was made salient. The impact of assimilation expectations and national identity content on the findings is discussed.
