Focusing at its starting point at the emergence of the concept of (super-) diversity in policy and academia, the article challenges the alleged theoretical and epistemic changes introduced by this new paradigm (Vertovec 2007) in the studies of race and ethnicity, pluralistic democracies, and even « multiculture » (Back 1994 ; Hall 1999). First we critically examine the main innovations claimed by the model, replacing them in a broader context of a posited « return of assimilation » (Brubaker 2001). Second we examine other sources of criticism, based for instance on empirical scrutiny and evidence from public policies analysis. We consider in conclusion the hypothesis of « whitening » (Bilge 2013) diversity and question thepossibility to invest the concept not normatively but critically, namely through athorough articulation to the principle of nondiscrimination
