Description
This study will allow us to refine the development of key components of the health messages lab and gain new knowledge about the effects of alternative formats to communicate uncertainty on participants beliefs, decisions, and behaviours.
The objectives of the randomized trial are:
- To compare the effects of three ways of communicating the overall uncertainty of the effects of wearing glasses to reduce the chance of getting COVID and
- To compare the effects of including the margin of error (confidence interval) compared to not including it.
The primary outcome for all 6 summary versions tested is understanding of the uncertainty.
For the 3 summary versions that include the margin of error (compared to those that do not), there is an additional co-primary outcome, assessing understanding of statistical uncertainty (i.e., precision of the effect estimates).
