This report examines the transformative role of behavioural insights (BI) in European Union (EU) policymaking, advocating for integrating BI early in the policy cycle to enhance policy effectiveness. It challenges the misconception that BI is limited to designing behavioural interventions with marginal impacts and demonstrates its potential to guide the development of both traditional policy instruments and behavioural interventions. 

The report underscores the importance of BI in identifying synergies and conflicts between policies across different areas, thereby improving policy coherence. It advocates for the use of BI in combination with systems analysis to achieve systemic changes. The policy relevance of this work lies in its timely contribution to evidence-based approaches, particularly in areas where the human dimension is key to policy success.
