Ethics approval and consent to participate
: The RAND Human Subjects Protection Committee has determined this study to be exempt. In this project, we are conducting secondary analyses of existing datasets. We will also be gathering survey data from members of two existing internet panels: Amazon Mechanical Turk (MTurk) and KnowledgePanel. MTurk participants are anonymous, and written consent for each survey is implicit when participants click “next” after reading the study explanation. Members of the KnowledgePanel have a written agreement with the company that manages that panel (Ipsos) when they join the panel and Ipsos does not require consent for each survey.
