The social sciences playa variety of multifaceted roles in the policymaking process. So varied are these roles indeed that it is futile to talk in the singular about the use of social science in policymaking as if there were one constant relationship between two fixed and stable entities. Instead to address this issue sensibly one must talk in the plural about uses of dif- ferent modes of social scientific inquiry for different kinds of policies under various circumstances. In some cases the influence of social scientific research is direct and tangible and the connection between the find- ings and the policy is easy to see. In other cases perhaps most its influence is indirect-one small piece in a larger mosaic of politics bargaining and compromise. Occasionally the findings of social scientific studies are explicitly drawn upon by policymakers in the formation implementation or evaluation of particular policies. More often the categories and theoretical models of social science provide a general background orientation within which policymakers concep- tualize problems and frame policy options. At times the in- fluence of social scientific work is cognitive and informational in nature; in other instances policymakers use social science primarily for symbolic and political purposes in order to le- gitimate preestablished goals and strategies. Nonetheless amid this diversity and variety troubling general questions persistently arise.
