Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators will recruit a national sample of parents of 7-10-year-olds to complete an argument strength ranking for either a simple forwarding message or between 3 and 6 randomly selected arguments from an overall set of 50 to 100 messages identified from various online sources. Parents will rate each message they see on measures of perceived argument strength/PME. Parents will also answer sociodemographic questions and then rank the believability of a set of anti-vaccine messages identified in a different study. Study findings will contribute valuable information to understanding the effectiveness of different inoculation messages.
