Fig. 3: Treatment effects on beliefs and intentions.

(left) Effect on beliefs about descriptive norms. Coefficients on treatment from a regression of beliefs about norms on treatment status, including centered covariates and interactions. In this analysis, treated respondents are those who receive the treatment before the question eliciting beliefs about norms. This will not agree, in general, with the treatment status for the main analysis given the randomized question order in the survey. There are n = 304,840 responses in the masking analysis, n = 70,078 in the physical distancing analysis, and n = 356,004 in the vaccination analysis. (right) Effect on intentions. Coefficients from regression of intentions on treatment, centered covariates, and their interactions. There are n = 323,085 responses in the masking analysis, n = 85,619 in the physical distancing analysis, and n = 365,593 in the vaccination analysis. Error bars are 95% confidence intervals centered around mean estimates. Source data are provided as a Source Data file.
