Beyond choice architecture: advancing the science of changing behaviour at scale

Area of Science:

• Behavioral Science
• Public Health
• Environmental Science

Background:

• Global health challenges necessitate large-scale behavioral change.
• Intervention effectiveness depends on both effect size and population reach.
• Choice Architecture, modifying physical micro-environments, is a promising but under-researched intervention strategy.

Discussion:

• Integrating basic (laboratory) and applied (field) research is crucial for realizing Choice Architecture's potential.
• This integration advances theory and generates scalable interventions.
• Evidence synthesis can inform and be updated by complementary lab and field studies.

Key Insights:

• Choice Architecture interventions can be designed to reduce consumption of meat, energy-dense foods, and alcohol.
• Modifying product availability and size are effective Choice Architecture strategies.
• These interventions demonstrate the synergy between controlled experiments and real-world application.

Outlook:

• Further research integrating laboratory and field approaches will optimize Choice Architecture interventions.
• This integrated approach can contribute significantly to addressing population and planetary health threats.
• Scalable Choice Architecture strategies hold promise for widespread public health benefits.
