How has the ability to express reflexivity, including regulating affect, come to be part of the bundled self that workers are required to be? This paper offers a rigorous genealogical analysis of the multiple histories of knowledge and power that have informed the emergence and shaping of ‘reflexive registers,’ or socially typified ways of speaking and reflecting about oneself that stand for morally marked models of selfhood. It takes as a starting-point programs documented in my ethnography of employability programs in London, UK where workers of all sorts are asked to learn to examine their personalities and to express their feelings. It then draws on original historiographical and ethnographic data that allows documentation of the logics and circumstances informing the emergence and development of reflexivity as a resource for employability. It argues for an interdisciplinary understanding of reflexivity and its communicability that theorises the workers as products of history, capital, and affect.
