Following my involvement in the Epistemology of Evidence-Based Policy research group, some my work concerns the foundations of science in policy: how ongoing scientific research or knowledge filters into decision-maker and policymaker action. Below, articles are organized by most recent.

Evidence-based policy (EBP) has become widely embraced for its commitment to greater uptake of scientific knowledge in policymaking. But what legitimizes EBP and in what respect are evidence-based policymaking practices better than other policymaking practices? In this article, we distinguish and refine three potential legitimizers of EBP. We suggest that evidence-based policymaking practices are better because they “follow the science,” because they focus on “what works,” or because they “follow the rules.” We discuss some consequences, for advocates of EBP, of consciously adopting one or other of these legitimizers. Finally, we examine whether it is appropriate to switch from advocating for EBP to advocating for evidence-informed policy.

When evidence-based policymaking is so often mired in disagreement and controversy, how can we know if the process is meeting its stated goals? We develop a novel mathematical model to study disagreements about adequate knowledge utilization, like those regarding wild horse culling, shark drumlines and facemask policies during pandemics. We find that, when stakeholders disagree, it is frequently impossible to tell whether any party is at fault. We demonstrate the need for a distinctive kind of transparency in evidence-based policymaking, which we call transparency of reasoning. Such transparency is critical to the success of the evidence-based policy movement, as without it, we will be unable to tell whether in any instance a policy was in fact based on evidence.
