Research on the security politics of the European Union is becoming increasingly abundant. To further the aims of this special issue on methodology among critical approaches to security, this article draws on the appropriation by this scholarship of the “social life of methods” debate to open two related lines of investigation. First, the article examines the inscription of researchers into European security politics not only as a limit to research, but as a method of access and analysis. The article looks particularly at the identification of researchers as “experts” by EU practitioners, and at expertise as method. The second line of investigation and reflection concerns the limits inherent to the way in which critical scholarship on security has appropriated the “social life of methods” discussion. The article argues that this is an opportunity to engage with methods in relation to concrete research endeavors, rather than to stage a theoretical discussion on methods.
