Beyond reflexivity and representation: diffraction as a methodological sensitivity in science studies

Abstract

ABSTRACT Against the backdrop of the broad reception of Karen Barad's framework of agential realism, it comes as a surprise that there has been little discussion so far of her core concept of diffraction in the social studies of science. This article aims to evaluate the methodological potentials of a diffractive approach for science studies. In order to achieve this, I will examine Barad's take on quantum mechanics, which serves as the foundation for her ethico-onto-epistemological framework of agential realism. In doing so, I will unpack the crucial role played by diffraction in reworking the relation between the objects of observation and the agencies of observation, and subsequently in reshaping the question of the referent of objectivity. Building on this analysis, I propose the notion of the researcher as transducer, demonstrating how such a take allows for the emergence of an understanding of the researcher as themselves materializing in intra-action with other human and more-than-human forces and practices. As I will show, such a diffractive approach not only shifts our attention even more to the performative power of research as a material practice but also to the constitutive nature of knowledge-making practices, along with their ethical and political implications.
