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.
