Science, society and shared expertise: a European issue? In recent years, the MML action plan has funded many projects designed to bring about a rapprochement between science (and scientists) and other civil society actors. The aim was to respond to social concerns about the various issues raised by science and to close the gap between scientific experts and society, especially during periods of crisis, when decisions that have a profound impact on society are taken on the basis of scientific findings. Other recent international organizations and initiatives have had similar objectives. At the same time, a wide range of sources of information and dissemination have emerged and developed in recent years, based on an extensive use of electronic tools and resources. While scientific information is becoming increasingly available, it has also paradoxically become increasingly subject to competition and criticism, and even ‘manipulation’. A growing number of societal issues and challenges surrounding science have also emerged, and the capacity to share scientific expertise democratically and consensually has become an issue that transcends national boundaries.
