United States and Italy
Unit of observation:
5,759 (3,100 USA + 2,659 Italy)
After providing informed written consent, respondents read an unrelated vignette to assess their attention. Those who did not answer a comprehension question correctly could not proceed with the study and exited the sample.
At the subject level, we randomized respondents at equal rates to a Placebo Control, where they read a message unrelated to the topic of the experiment, a Masks Protect You treatment that explains how masks stop some percentage of SARS-CoV-2 virus particles in the air from being inhaled by healthy people, and a Masks Protect Others treatment that explains how masks stop some percentage of SARS-CoV-2 virus particles from being expelled into the air by sick people.
Our core randomized treatments allow us to test whether beliefs about mask efficacy and the mask wearing behavior of others as described in a vignette affect one’s own mask wearing and one’s willingness to encourage mask wearing by others.
