The transmission game: Testing behavioral interventions in a pandemic-like simulation.

Area of Science:

• Behavioral economics
• Epidemiology
• Public health interventions

Background:

• Pandemics require behavior change to mitigate disease spread.
• Balancing individual risk-taking with social costs is crucial for effective interventions.
• Policymakers need evidence-based strategies to encourage socially advantageous behaviors.

Purpose of the Study:

• To evaluate the effectiveness of different nonpharmaceutical interventions on behavior during pandemics.
• To identify which behavioral interventions are most successful in promoting public health.

Main Methods:

• Developed the transmission game framework, integrating outbreak simulations with large-group experiments.
• Conducted two studies with 700 participants to test five distinct behavioral interventions.
• Utilized monetary stakes to incentivize participants' behavior in simulated pandemic scenarios.

Main Results:

• Significant differences were observed in the effectiveness of the five tested interventions.
• A simple injunctive-norm message was the most effective intervention.
• Interventions enhancing consequence anticipation were moderately effective.
• Descriptive norms and concurrent risk information interventions showed no significant impact on risk-taking.

Conclusions:

• Injunctive-norm messaging is a highly effective strategy for promoting public health behaviors during pandemics.
• Interventions should focus on clear social expectations and improving consequence awareness.
• Future research should explore the scalability and long-term impact of effective interventions.
