The chapter discusses how the study of identifications relate to other research and theorizing on epistemic governance. It discusses previous scholarship on identity construction in various schools of thought: symbolic interactionism, the Birmingham school cultural studies, new institutionalism, structuralism, ethnomethodology, and membership categorization analysis. The epistemic governance framework gives the study of identifications an extra twist, because it approaches identifications from the viewpoint of argumentation and persuasion. To achieve their goals, actors are creative in forging and strengthening associations between a group membership and what it entails. In such instances, well-established collections of categories are also used metaphorically. Metaphors are useful in depicting and categorizing complex and abstract objects. The chapter relates identifications to the other two objects of epistemic work—ontology and moral norms—and points out that these three always exist together in persuasion work. By way of conclusion, the chapter suggests that it is increasingly important to analyse how evidence supporting political decisions is created and fabricated, and how facts and figures are made to serve predefined objectives. Furthermore, the rousing and using of emotions as ways to create likeminded communities and persuade the members of what needs to be done is also a theme that deserves more scholarly attention.
