How far should we rely on science to make political decisions? What makes a good science advisor — or a good science advice system? What do we do when the evidence is incomplete or controversial? What happens when science advice goes wrong and how can we fix it? We explore these questions, and many more, in conversation with the researchers, policymakers and communicators who make science advice happen around the world. The Science for Policy podcast is produced the Scientific Advice Mechanism to the European Commission and hosted by Toby Wardman. The many and varied opinions expressed on this podcast are those of the guests themselves. They do not necessarily represent the views of SAPEA or the European Commission.

Do policymakers and scientists have different understandings of "risk"? How can scientific uncertainty be pinned down and quantified? When experts disagree about the evidence, is there anything useful that the policymaker can take away from that disagreement?
Bart Koelmans discusses these questions with Toby Wardman of SAPEA. We also discuss the strength of the evidence for harm from microplastics, the limits of the natural sciences, what numerical value of probability is implied by the word "probably", and how English speakers should try to pronounce the word "Wageningen".
Bart is a professor in Aquatic Ecology and Water Quality at Wageningen University and at Wageningen Marine Research. His main research is on the risks and impacts of microplastic pollution, on which topic he has chaired science advice groups for the UN and European Commission as well as national governments and other policymakers.
As always, the opinions expressed in this episode are those of the speakers and not necessarily those of SAPEA or the European Commission.
