 Systems thinking is a powerful methodology for understanding complex issues and developing solutions. It allows us to see the relationships between elements within a system and the spaces in between them. Recent research by Haynes has shown that policymakers value this approach, but also want more practical solutions. This highlights the tension between complexity and simplicity, and the need for evidence-based decision-making. Evidence centers have emerged to help bridge this gap, providing decision-makers with tools and dashboards of proven interventions. These can be used to evaluate complex policy problems, while still meeting the need for accountability and transparency. Communication skills are essential to convey these insights in a clear and engaging manner, while maintaining the complexity of the issue. This article was authored by Tara Lamont.
