The social sciences have played a key role in shaping public understanding of processes of immigrant integration in Europe. Faced with the challenges of ongoing immigration and growing cultural diversity, European countries have expended substantial resources to develop the knowledge required to understand these issues and to control them. The way in which this has happened, however, varies from one country to another. Countries differ not only with respect to how dialogues between scientific research and policy making are organized, but also with respect to how the resulting knowledge is then used by policy makers. One intervening factor is the gradual politicization of public discourse on the migration/integration issue, not only at a national level, but also at an institutional EU-level. In this panel session we will assess what research-policy dialogues looked like initially in several European countries and how these dialogues have developed into a much more complex science-society dialogue on these matters over the years. We will do so from the perspective of the changing role of science in society, but we will also assess the impact of some major social transformations, especially those that are related to immigrant integration, on the development of social scientific research. The presenters on the panel are currently collaborating on the DIAMINT project, funded by the Volkswagen Stiftung, which analyses the reconfiguration of science-society dialogues on immigrant integration in a number of European countries (Austria, Germany, Italy, the Netherlands, the United Kingdom) as well as on the EU level.
