Abstract
This article argues that there are at least three different versions of methodological nationalism: state-centrism (unjustified supremacy granted to the nation-state), territorialism (understanding space as divided in territories), and groupism (equating society with the nation-state’s society). If these three versions are logically distinct, as it will be shown, the typology can serve as a tool to weight the influence of methodological nationalism in the social sciences. The paper has three sections arguing that 1) the three versions are all present in the literature on methodological nationalism without always being distinguished; 2) the epistemological problems raised by methodological nationalism are sometimes misunderstood as ontological or normative questions about globalization and national borders; 3) the three versions of methodological nationalism can be shown to be logically independent by a few examples.
