Hear from Prof. Aled Jones, Director of the Global Sustainability Institute at Anglia Ruskin University, as we dive into the role of models in shaping policy, and particularly their weaknesses.

Models are not neutral – they reflect the assumptions, values, and agendas of those that create and use them. Using the energy system as an example, models can (and have been) used to protect the status quo. In part, this is because many of the models are based on the notions of 'equilibrium' and so they simply can't cope with major structural changes, such as the current energy transition. But it can be difficult for policy makers to switch towards models that are arguably more suited to the job.

So, what can we do to supplement the models? One very effective approach is to adopt a structured process of expert elicitation, where we use the insights of experts to uncover vulnerabilities and risks. To bring it to life, we explore how this has worked in the case of the food system. We discuss:

• The role that models play in shaping energy policy, and how they can lead us astray;
• How expert judgment and insight can help address model blind spots; and
• Finally, what are the key lessons for risk professionals?
