Most conceptualizations of the linkage between science and politics have traditionally been informed by rationalist concepts of science and decision-making. The result has been a false dichotomy between (legitimate) rational research utilization and (illegitimate) political research utilization. This dichotomy must be overcome, on normative as well as empirical grounds. Scientifically generated knowledge constitutes an important, but on the whole unquantifiable part of the enormous store of knowledge which participants in the politico-administrative decision-making process apply to their practical tasks. To understand the complex interfaces between social science research and the political-administrative decision-making process, it is necessary to be aware that research is transferred to, and becomes part of, a discourse of action, in the philosophical as well as the everyday practical sense - a discourse in which (self)reflecting participants deliberate on and debate norms and alternatives with a view to concrete action. This makes the contribution of science to policy making both less tangible and potentially more influential than is usually assumed.
