Numerous ethical guidelines and regulatory frameworks have been developed to assess and shape digital systems. However, these efforts often rest on the dubious assumption that individuals and organisations possess the necessary capacities to assess such systems in terms of justice, reliability, and other normative standards – especially given the growing complexity and corresponding opacity of many digital models. This issue is therefore of central importance to both legal and ethical debates surrounding AI and digital systems in general. The contributors to this volume propose a new approach to digital governance to enhance the capacity to evaluate and shape digital systems.
