  Since critical theories and other alternative theoretical perspectives question the existing status quo, make knowledge dependent on power, and emphasize identity formation and social change, they are not traditional or non-positivist. They are sometimes called “reflectivist” or “post-positivist” (Weaver 165) and represent a radical departure from the neorealist and neoliberal “rationalist” or “positivist”  international relation theories. Constructivists, such as Alexander Wendt, try to build a bridge between these two approaches by on the one hand, taking the present state system and anarchy seriously, and on the other hand, by focusing on the formation of identities and interests. Countering neorealist ideas, Wendt argues that self-help does not follow logically or casually from the principle of anarchy. It is socially constructed. Wendt’s idea that states’ identities and interests are socially constructed has earned his position the label “constructivism”. Consequently, in his view, “self-help and power politics are institutions, and not essential features of anarchy. Anarchy is what states make of it” (Wendt 1987 395). There is no single logic of anarchy but rather several, depending on the roles with which states identify themselves and each other. Power and interests are constituted by ideas and norms. Wendt claims that neorealism cannot account for change in world politics, but his norm-based constructivism can.
