A few weeks ago, the European Commission issued a report entitled Understanding our political nature: how to put knowledge and reason at the heart of political decision-making. Sounds like something of interest to evaluators, no? What follows is from the European Commission website.

Recognising that advances in behavioural, decision and social sciences demonstrate that we are not purely rational beings, this report brings new insights into our political behaviour and this understanding have the potential to address some of the current crises in our democracies.

Sixty experts from across the globe working in the fields of behavioural and social sciences as well as the humanities, have contributed to the research that underpins this JRC report that calls upon evidence-informed policymaking not to be taken for granted.

There is a chapter dedicated to each key finding which outlines the latest scientific thinking as well as an overview of the possible implications for policymaking.

The key findings are:

• Misperception and Disinformation: Our thinking skills are challenged by today's information environment and make us vulnerable to disinformation. We need to think more about how we think.
• Collective Intelligence: Science can help us re-design the way policymakers work together to take better decisions and prevent policy mistakes.
• Emotions: We can't separate emotion from reason. Better information about citizens' emotions and greater emotional literacy could improve policymaking.
• Values and Identities drive political behaviour but are not properly understood or debated.
• Framing, Metaphor and Narrative: Facts don't speak for themselves. Framing, metaphors and narratives need to be used responsibly if evidence is to be heard and understood.
• Trust and Openness: The erosion of trust in experts and in government can only be addressed by greater honesty and public deliberation about interests and values.
• Evidence-informed policymaking: The principle that policy should be informed by evidence is under attack. Politicians, scientists and civil society need to defend this cornerstone of liberal democracy.
