Many political philosophers theorise not only for the sake of pure theory, but also because they want to convince citizens and policymakers to bring about changes in the real world.

Such policy-oriented research often draws on interdisciplinary methods, integrating empirical insights and normative and conceptual arguments. This, however, raises methodological challenges of its own. For example, how to deal with the fact that the social sciences are fragmented and different disciplines work with different paradigms and methodologies? How can philosophers, who bring their own normative assumptions openly to the table, deal with the – sometimes implicit – normativity that is also inherent in many other lines of research? What level of abstraction of normative arguments, eg basic normative theories or mid-level overlapping principles, should philosophers draw on when discussing with policymakers? And how to deal with the fact that in the current political climate in many countries, distrust towards “experts” also extends to philosophers?
