The Center for Philosophy, Science, and Policy (CPSP), aims to provide a platform for research and advice for science-based policy. It gathers experts in fields of research interested in collaborative work for the development of encompassing frameworks for timely responses to current social challenges in a principled, yet flexible way. A special emphasis is given to foundational expertise in the scientific methods and in strategic and institutional interactions in the scientific ecosystems, and to a systematic and critical appraisal of the available evidence, its uses for policy interventions and for policy evaluations.
