The article examines the role played by policy advice institutions in the governance of ethically controversial new and emerging science and technology in Europe. The empirical analysis, which aims to help close a gap in the literature, focuses on the evolution, role and functioning of national ethics advisory bodies (EABs) in Europe. EABs are expert bodies whose remit is to issue recommendations regarding ethical aspects of new and emerging science and technology. Negative experiences with the impacts of science and technology (...) in the past have resulted in calls for increased transparency and broader participation and pluralism in expert advice and policy decision-making. Do national EABs function as inclusive, anticipatory “hybrid forums”? Or do they resemble more “classical” expert-oriented bodies, inspired by technocratic or decisionist approaches? As part of the empirical analysis of the role and functioning of institutional ethical advisory structures in 32 European countries, an extensive analysis of EAB websites and the content of publicly available documents on such institutions has been carried out, supplemented by an online survey of representatives of the EABs. One major finding of the empirical analysis is the very uneven distribution of “hybrid forum” features of EABs across Europe. (shrink)
