Mapping deliberation: calculation, articulation and intervention in the politics of organ transplantation

This paper reflects on the aims and outcomes of an innovative methodology of participatory technology appraisal, called Deliberative Mapping, which seeks to contribute to theoretical debates and practical experimentation around what it might mean to bring the technosciences into democracy. Deliberative Mapping is a hybrid methodology, involving both calculative and deliberative processes, which seeks to map the entanglements of biotechnological imbroglios, and translate these connections into the contexts of decision-making. Through application to the case study of organ transplantation, these procedures of calculation and articulation are critically examined, exploring their aim to reduce asymmetries between scientific, political, economic and other framings of the issue and their operation in contexts already complexly structured through existing power relations, which indicate the challenge of co-fabricating these experimental forms of intervention into political facts.
