 METHODS: Internet survey with colleagues from Carnegie Mellon University using Amazon Mechanical Turk - a web tool that recruits people willing to do surveys Participants will be asked to read a short scenario about a new drug facts are based on a real drug but the investigators use a fictional name and answer questions about how well they think the drug works, how safe it is, etc. People will be randomized to one of 5 versions of the scenario differing in how explicitly they explain what breakthrough means. The information in the scenario is drawn from FDAs own press release about the drug.
