Policies on preventing radicalization and recruitment to violent Islamist organizations have been widely criticized for reinforcing negative stereotypes of Muslims as a group. Sweden has stood out by international comparison by announcing an approach built on inclusion and participation, especially with regard to Muslim civil society. But what does it mean to make a policy process inclusive and participatory? How can values of inclusion and participation be combined with efficient implementation and realization of policy goals, especially in a policy area where discourse and practice have tended to reinforce patterns of exclusion and discrimination? This article develops a framework that puts the roles of participants at the center: what expectations, boundaries and capacities come with an invitation to participate? Based on interviews with actors involved in the Swedish policy process, including Muslim civil society leaders, the study suggests that participation, in this case, meant primarily being present, thereby confirming commitment and stakeholder status and contributing legitimacy, and providing instrumental knowledge and communication networks. While Muslim representatives were often not expected to be more involved, some indicated that they themselves hesitated to go beyond these roles for several reasons. They expressed a concern that merely having opinions or critique could be interpreted as ‘radical’ and as not accepting the idea that Muslims as a group should have special responsibilities for preventing radicalism. One way of overcoming such obstacles is through subtle, indirect exercises of influence that allow policy-makers and administrators to anticipate the concerns and interests of affected groups without requiring their direct participation.
