Abstract
Drawing on actor-network theory, this paper challenges the traditional analytical separation of the socalled social and the so-called technical. First, observational data of an interactional event between a social worker and a client is introduced. Second, the techno-social heterogeneity of the event is elucidated through an analysis based on the concept of translation. Third, the precarious and temporary natures of the techno-social hybrids are discussed through the concept of performance. Finally, the techno-social is proposed as a new object for social science
