From evidence based policy to the good governance of evidence

As Paul Cairney’s blog noted, many of those promoting evidence-based policymaking (EBPM) fail to engage with the political nature of the arena in which evidence is being used.  Policymaking is fundamentally political in that it requires decisions about which social goals to pursue, or how to prioritise between our multiple (often competing) social values. This reflects insights from political theorists that date back half a century or more (c.f. Albert Brect) who have explained that policymaking is about deciding what a good society looks like – a question science itself cannot answer.

And yet we see continual calls to scale up or institutionalise the use of evidence which never stop to consider some fundamentally important political questions – such as what evidence should be promoted, by whom, and for which of the many social concerns typically at stake in policymaking.

The answers to these questions – about which evidence, about what concerns, by whom – have implications for whose interests are promoted or legitimised within the policy sphere. This tension underlies some of the most important contemporary debates about evidence use today – often seen to be waged in terms of a ‘paradigm war’ between advocates of better evidence on the one hand – who argue that we need to ensure rigour and scientific good practice; and critical policy scholars – who argue that important value debates risk being depoliticised or obscured by particular uses of evidence.

In a new book I attempt to move these debates forward. I argue that we need to recognise that in policy arenas, the systems and processes that shape how evidence is used can be understood as governing the use of evidence for policymaking. Institutionalising or scaling up new ways of using evidence, are thus not simply technical exercises in skills building, but are fundamentally a normative (value driven) process. It sets in place the structures, rules, and practices that will direct how different forms of evidence, for different social concerns, are used to guide policy decisions.

If institutions govern evidence use, and if the decisions on how to arrange them are political ones, this begs the question: which values or norms should be followed when working to improve the use of evidence? What, in other words, can we hold up as key principles of the good governance of evidence? My book looks to the stakeholders in the aforementioned debate to find answers to this. Champions of evidence typically uphold a key set of normative concerns that are fundamentally about achieving scientific best practice. Critical policy scholars, on the other hand, present a separate, but just as important, set of concerns over democratic representation in policymaking. These need not be mutually exclusive, however. Both perspectives can be used to form a set of principles that underpins a conceptualisation of good governance of evidence. Evidence can be said to be well governed when we have systems in place that ensure that rigorous, systematic and technically valid pieces of evidence are used in decision-making processes that are representative of, and accountable to, the populations served.

This concept allows us to return to our goal of building institutions to improve evidence use for policymaking, but to do so in ways that are appropriate to the political nature of the policy process.
