Purpose: For more than 20 years, research on the communicative constitution of organizations (CCO) has drawn on interactional data to offer novel explanations of how organizational phenomena emerge, change, and stabilize in and through communication. Accordingly, the idea of “never leaving the terra firma of interaction” has become a tenet of CCO research, guiding scholars’ theorizing, data collection, and analysis. The aim of this paper is to reflect on and enrich this tenet. Design/methodology/approach: First, this paper traces the history of the concept of the terra firma of interaction and its usage until now. Second, drawing on ethnographic writings on complicit reflexivity and on the two first authors’ doctoral research experiences, this paper identifies current limitations of the terra firma notion. Findings: Reflecting on these experiences, the idea of composing with the terra fluida (fluid ground) of interaction is proposed as an enrichment of the terra firma of interaction concept because it advances present discussions about CCO researchers’ positionality and reflexivity while opening up new paths for understanding how organizational phenomena unfold as relational fields in processes of communication. Originality/value: This paper questions and reevaluates the role of the researcher in CCO scholarship and, in doing so, offers new insights into the value of acknowledging researchers’ entanglement and complicity with the fluid fields of interaction they aim to understand.
