This page brings together my work on ‘evidence-based policymaking’, including a book The Politics of Evidence-Based Policy Making, some journal articles, and many posts including The Science of Evidence-based Policymaking: How to Be Heard. Please scroll down to see the main argument and links to further reading (including a free pre-publication version of my book) and click Evidence to see a forthcoming series of articles on evidence and policy.

“Cairney wisely navigates between the naïve peddlers of ‘evidence-based policy’, and the grumpy cynics who think such an endeavour is hopeless. The book gives some much needed insights into the psychology, political theory and cognitive biases of decision-making. It’s essential reading for anybody with a practical interest in seeing evidence have – at the very least- a foot in the policymaker’s door” Jonathan Breckon, Head of Alliance for Useful Evidence
The main argument
Policymakers are not willing or able to consider all evidence relevant to policy problems. Instead, they employ two shortcuts: ‘rational’, by pursuing clear goals and prioritizing certain kinds and sources of information, and ‘irrational’, by drawing on emotions, gut feelings, deeply held beliefs, and habits to make decisions quickly.
This action takes place in a complex policymaking system in which policymaker attention can lurch from issue to issue, policy is made routinely in subsystems, and the ‘rules of the game’ take time to learn.
Many studies focus only on the first short cut. They identify the problem of uncertainty that arises when policymakers have incomplete information, and seek to solve it by improving the supply of information and encouraging academic-practitioner networks and workshops.
They ignore the importance of a wider process of debate, coalition formation, lobbying, and manipulation, to reduce ambiguity and establish a dominant way to ‘frame‘ policy problems. While scientific evidence cannot solve the problem of ambiguity, persuasion and framing can help determine the demand for scientific evidence.
Therefore, the second solution is to work out how best to engage in a process of framing and persuasion by, for example, forming coalitions with actors with the same aims or beliefs, and combining scientific information with simple stories to exploit or adapt to the emotional and ideological biases of policymakers.
This is less about packaging information to make it simpler to understand, and more about responding to the ways in which policymakers think and, therefore, how they demand information.
In the book, I present this argument in three steps:
- I bring together a range of insights from policy theory, to show the huge amount of accumulated knowledge of policymaking on which other scientists and evidence advocates should draw.
- I discuss two systematic reviews – one by Oliver et al, and one that Wellstead and I developed – of the literature on ‘barriers’ to evidence and policy in health and environmental studies. They show that the vast majority of studies in each field employ minimal policy theory and present solutions which focus only on uncertainty.
- I identify the practical consequences for actors trying to maximize the uptake of scientific evidence within government.
My conclusion has profound implications for the role of research and scientific experts in policymaking. Scientists have a stark choice: to produce information and accept that it will have a limited impact (but that scientists will maintain an often-useful image of objectivity), or to go beyond one’s comfort zone, and expertise, to engage in a normative enterprise that can increase impact at the expense of objectivity.

Blog posts: 7 key themes
1. Use psychological insights to influence the use of evidence
My most-current concern. The same basic theme is that (a) people (including policymakers) are ‘cognitive misers’ seeking ‘rational’ and ‘irrational’ shortcuts to gather information for action, so you won’t get far if you (b) bombard them with information, or (c) call them idiots.
Three ways to communicate more effectively with policymakers (shows how to use psychological insights to promote evidence in policymaking)

2. How to use policy process insights to influence the use of evidence
I try to simplify key insights about the policy process to show to use evidence in it. One key message is to give up on the idea of an orderly policy process described by the policy cycle model. What should you do if a far more complicated process exists?

3. How to combine principles on ‘good evidence’, ‘good governance’, and ‘good practice’
My argument here is that EBPM is about deciding at the same time what is: (1) good evidence, and (2) a good way to make and deliver policy. If you just focus on one at a time – or consider one while ignoring the other – you cannot produce a defendable way to promote evidence-informed policy delivery.

4. Face up to your need to make profound choices to pursue EBPM
These posts have arisen largely from my attendance at academic-practitioner conferences on evidence and policy. Many participants tell the same story about the primacy of scientific evidence challenged by post-truth politics and emotional policymakers. I don’t find this argument convincing or useful. So, in many posts, I challenge these participants to think about more pragmatic ways to sum up and do something effective about their predicament.

6. Using storytelling to promote evidence use
This is increasingly a big interest for me. Storytelling is key to the effective conduct and communication of scientific research. Let’s not pretend we’re objective people just stating the facts (which is the least convincing story of all).
7. The major difficulties in using evidence for policy to reduce inequalities
These posts show how policymakers think about how to combine (a) often-patchy evidence with (b) their beliefs and (c) an electoral imperative to produce policies on inequalities, prevention, and early intervention. I suggest that it’s better to understand and engage with this process than complain about policy-based-evidence from the side-lines. If you do the latter, policymakers will ignore you.
