Communicating the potential outcomes of policies

Project - Communicating the potential outcomes of policies

What Works logos

Decision makers need communications that succinctly describe the potential harms and benefits of different options, and this problem is widely recognised in situations such as patients choosing medical treatments. Best practice has evolved towards developing formats that give clear, unbiased information to support decisions. However, policymakers or citizens evaluating a policy are rarely given such balanced and easily understood summaries of the potential outcomes of their decision, despite the enormous consequences of public policy.

Information on the potential outcomes of policy decisions are more complex than those for individuals:

  • the outcomes will be different from different people (there will be winners and losers)
  • there will usually be many different outcomes/implications, each measured with a different metric (such as financial, environmental, health implications etc)
  • the timescales over which the outcomes might play out could be much longer
  • the uncertainties surrounding the outcomes could be much larger

Our first major paper on this problem is a review of current methods of evidence communication for policy makers: Winner and losers: communicating the potential impacts of policies. We are now working on whether some of the lessons learned in the field of healthcare can be applied to the communication of evidence to policymakers, helping them make decisions.

We also completed a 2019 survey with the users of the websites of several of the UK's What Works Centres, which commission and synthesise evidence on a range of policy topics. We found out what information is important to the Centre users and how they interpret the current presentations of evidence (such as the online toolkits, eg. the Education Endowment Foundation evidence Toolkit, and theCollege of Policing's Crime Reduction Toolkit). The preliminary report is available here and is being written up for a scientific article.

We are also currently doing empirical testing on different methods of communicating evidence, comparing them in an individual and policy decision making contexts.
