The researchers used a bottom-up approach to understand people's experiences and map system trajectories. They identified variables from successful and unsuccessful cases to build a system map. Testing revealed selective learning showed significant variation and could be a behavioral leverage point for change. The researchers are prototyping a peer-to-peer learning video using role models to change mental models and teach new techniques. In conclusions, the relationship between behavior and systems design was promising, identifying key behaviors with systemic impacts, and testing different levers to find the most promising for change.
