Experiment 1 treatment messages and theoretical underpinnings.
Fig 1.
Covariate-adjusted treatment effects estimated using OLS regression with robust Huber-White standard errors.
Estimates displayed with 95% confidence intervals. Each panel shows the effect of each treatment message relative to the Baseline Informational condition for a primary outcome scale. All outcomes scales were coded such that higher values indicate more positive attitudes or intentions toward social distancing.
Fig 2.
Compared to the placebo control, the Baseline Informational message, the Reframing Bravery message, and the Other-regarding, Linear Cooperation increase beliefs and reported behavioral intentions to practice social distancing. These are OLS regression coefficient estimates for each primary outcome by treatment compared to the placebo control with 90% confidence intervals. The dashed vertical line represents the effect of the Baseline Informational Message on an outcome. All outcomes scales were coded such that higher values indicate more positive attitudes or intentions toward social distancing.
Fig 3.
Experiment 2 individual social distancing items.
The Reframing Bravery and Other-regarding, Linear Cooperation message increase respondents reported intentions to not engage in key behaviors to reduce the spread of COVID-19 and to cooperate with government officials, even compared to the Baseline Informational message. This figure shows OLS regression coefficient estimates compared to the Control message with 95% confidence intervals. All outcomes scales were coded such that higher values indicate more positive attitudes or intentions toward social distancing.
