This document discusses a techno-scientific approach to understanding how users come to trust AI-generated deepfake content. It proposes studying deepfakes from a system perspective, looking at the network of relationships between users, AI systems, and their environments, rather than focusing only on the technical aspects of deepfakes or user characteristics. This approach sees knowledge as produced through the partnership between humans and technologies. It aims to provide a more holistic understanding of deepfakes in order to inform policy responses that address their sociotechnical dimensions rather than just their technical aspects.
