"Behavioral Science's Impact on COVID-19 Policy: A Synthesis of Success"

A synthesis of evidence from 747 pandemic-related research articles has found support for 16 out of 19 claims made by behavioural scientists in April 2020 regarding the use of behavioural science in reducing the impacts of COVID-19. The strongest evidence supported claims that culture, polarization, and misinformation would affect policy effectiveness, as well as claims that trusted leaders and positive social norms increase adherence to interventions. However, there was no evidence to support claims that highlighting individual benefits or protecting others would be effective. The study highlights the importance of using empirical evidence to inform policy decisions and the need for a standardized approach to evidence selection and synthesis.
