The Epistemology of Evidence-Based Policy: How Philosophy Can Facilitate the Science-Policy Interface

February - June 2023

How well do masks protect in the pandemic? How do the side effects of vaccination compare with the consequences of the disease? What is the impact of school closures on students’ mental health? During the Covid 19 pandemic, it has become clear how heavily political decisions rely on information from science. And it has become evident that research findings can inform policy decisions, but cannot replace them.

The pandemic has thus provided a vivid example of the problems posed by evidence-based policy (EBP) approaches. The basic idea of these approaches, which more and more governments are adopting, is that decisions should be based on evidence that can be or has been externally verified and validated. Measures and programs should also be reliably evaluated, preferably with the participation of interested citizens. This is intended to improve the quality of decisions and measures, while at the same time ensuring greater transparency and consistency in decision-making.

Yet adopting EBP creates epistemic responsibilities. First, it must be clear how information is obtained and how it is evaluated; when it is necessary to obtain additional information, and what information may not be considered at all. What, for example, counts as evidence? Who is responsible for providing evidence? Where should the burden of proof lie? Which experts can be trusted, especially when they disagree? How do the values and interests of individuals and organizations affect what evidence is gathered, how it is interpreted, and what policy decisions are made (partially) on that basis? How far do our epistemic obligations extend?

In addition, it must be clarified how decisions under uncertainty are made, because science, too, can usually provide only limited and provisional knowledge, for example, in the case of an emerging infectious disease. The questions scientists deal with are also very different from the questions politicians have to answer. Scientific results thus must be prepared in such a way that they can be understood by those responsible in politics, while politicians must at least to a certain extent engage with the scientific way of working and thinking to come to responsible decisions. Thus, communication problems often arise at the interface between science and politics.

How do we decide on the basis of statistical data? How should a study with a result that is statistically not significant be evaluated? How many test subjects are sufficient for a study to be convincing? How does the duty to seek further evidence relate to the duty to act quickly to save lives? In addition, how is scientific evidence evaluated in relation to other factors, such as communicability and acceptability of decisions for the public? Can the attempt to rely on scientific evidence do justice to the necessary complexity of political negotiation processes? Or could it ultimately lead to an escape from responsibility on the part of decision-makers?

Many of these challenges are ethical and epistemological in nature. Therefore, in this research group we bring together philosophers with policy makers and experts from the fields of science, politics, regulation and legislation. Together, we will explore successes and failures to acquire, consider or incorporate evidence into public policy, using real-world cases where conflicting values exists in environmental biosecurity and public health.

Biases and Incentives in the Acquisition and Consideration of Evidence

11 - 12 May 2023

The workshop will focus primarily on so-called 'biases in the acquisition and consideration of evidence', although presentations will also discuss the epistemological problems of evidence-based policy-making in relation to the pandemic and to biosecurity management. These problems include:

  • one-sided acceptance of evidence/research findings
  • lack of consideration of marginalised groups
  • the lack of transparency about value judgements that go into policy making
  • the possible misinterpretation of scientific methods
  • the handling of knowingly leaky evidence/uncertainty

Other questions are whether there is 'permissible bias', how the systematic intimidation of scientists affects evidence acquisition and consideration and the problems associated with the politics of evidence utilization.

Epistemic Standards of Due Care

28 - 29 June 2023

The workshop will deal with the question of what it means to hold beliefs responsibly and what standards of epistemic due care are appropriate in the context of public policy. While this question is increasingly attracting attention in philosophical circles, this is still an emerging field of research in epistemology and much more so in philosophy of public policy. The workshop will therefore address the following questions:

  • What are the epistemic obligations of different agents involved in evidence-based policy?
  • Which different roles and responsibilities for knowledge producers (researchers), knowledge users (policy makers) and knowledge brokers (intermediary organizations) can be identified?
  • What are policy makers epistemic obligations to be 'in the know', to avoid potentially harmful ignorance and to have enough information for responsible action?
  • How do scientists and policy makers act responsibly in a socio-political environment where certain groups of people have been discredited or taken less seriously in their capacity as 'knowers' and certain types of evidence feature less prominently in policy-making?
  • Policy-making is a group-based process: How does knowledge have to be distributed in a group for the group to be able to act/adopt decisions based on that knowledge? How can groups know or fail to know certain things/adopt certain beliefs?
  • How does the epistemic environment impact policy-makers and when is such impact problematic?
