Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. SSB warnings will be perceived as more effective than the control (message topic)
2. Icon and graphic warnings will be perceived as more effective than text-only warnings (message type)
The investigators will also examine the interaction of warning topic and warning type, but have no specific hypothesis about this interaction.
Finally, the investigators will test the following predictions about the secondary outcomes:
SSB warnings (vs. control), as well as icon and graphic warnings (vs text.warnings), will lead to lower perceived product healthfulness, lower purchase intentions, and higher cognitive elaboration.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Setting: The trial will take place online on a survey developed using Qualtrics.
Recruitment: Participants will be recruited online by CloudResearch PrimePanels, a survey research platform with access to over 20 million participants. As such, participants will have to be PrimePanels members in order to participate.
Informed Consent: After determining eligibility, eligible participants will be directed to a page on Qualtrics with the consent form. Participants acknowledge their consent in the study by clicking the "next page" arrow and proceeding to the study.
Randomization: After consenting, the participant is randomly assigned to to view one of the 5 warning topics. "WARNING: High in added sugar" (added sugar), "WARNING: Excess consumption of drinks with added sugar contributes to weight gain" (weight gain), "WARNING: Excess consumption of drinks with added sugar contributes to type 2 diabetes" (Type 2 diabetes), "WARNING: Excess consumption of drinks with added sugar contributes to heart damage" (heart damage), and "Please refrain from littering" (control). Within each of the four experimental arms, participants see the message displayed on four different types of warning designs: a text warning on a square background, a text warning on a octagon background, and icon warning, and a graphic warning. Within the control arm, participants see the message displayed on three different types of warning designs: a text warning on a square background, an icon warning, and a graphic warning. Participants randomly see the different warning designs in a random order.
Survey: The participants complete a survey answering behavioral perceptions and intentions questions about the different warning labels.
