Study Overview
Brief Summary
Participants will be randomly given one of two formats containing descriptions of health interventions. In one format, participants will have to read short summaries where results of the intervention are presented as frequencies and the side effects of health intervention are presented as percentages, while in another format the frames will be reversed (results will be presented as percentages and side effects as frequencies). After reading, participants will be asked several questions about the content of the summary and its conclusions.
