A better understanding of human behaviour can lead to better policies. If you are looking for a more data-driven and nuanced approach to policy making, then you should consider what actually drives the decisions and behaviours of citizens rather than relying on assumptions of how they should act.
You can start applying behavioural insights (BI) to policy now. No matter where you are in the policy cycle, policies can be improved with BI through a process that looks at Behaviours, Analysis, Strategies, Interventions, Change (BASIC). This allows you to get to the root of the policy problem, gather evidence on what works, show your support for government innovation, and ultimately improve policy outcomes.
This toolkit guides policy officials through these BASIC stages to start using an inductive and experimental approach for more effective policy making.
