This trial does not extend or rely on any prior RCTs.
This research seeks to collect information and beliefs about the COVID-19 pandemic. We hope to better understand the factors determining how and why people hold certain beliefs over others.

Primary Outcomes

Primary Outcomes (end points)
Following treatment, participants are asked to complete a set of outcomes questions that are broadly related to two main categories. First, participants will be asked questions related to trust, polarization, and activism. Second, they will be asked questions about the pandemic and vaccine hesitancy.

Experimental Design

Experimental Design
Recruitment occurs in two waves. In these waves, we randomize treatment and estimate effects. In our main estimates, we pool all waves . We use an advertisement campaign on Facebook to recruit from an active online community. Participation will be filtered in such that the survey is only viewable to those who are older than 18 years old. This also gives us a representative sample from across the United States throughout 2021 and samples from a population that is actively engaged in online activities, a natural setting through which treatment is actually administered.

Upon starting the survey, participants are asked to consent followed by a variety of demographic questions, including gender, age, and political orientation. Following recruitment, participants are randomly assigned into one of the four different groups. Details of these groups is hidden so as to not influence results.
