The document discusses the emerging field of the science of science policy (SoSP). SoSP aims to provide quantitative analysis and tools to help policymakers assess the impacts of scientific investments and improve understanding of science and innovation dynamics. An interagency task group was formed to develop a coordinated federal approach to SoSP. They identified key scientific questions around understanding science/innovation, investing in science/innovation, and applying SoSP to national priorities. The task group recommends establishing frameworks and research priorities to address these questions and developing new tools and data to support more rigorous quantitative analysis for science policy decisions.
