  • To participate in the experiment, individuals must have been located in the United States, had a Mechanical Turk approval rating of at least 98%, have completed at least 1,000 previous tasks on Mechanical Turk, and have passed two attention check questions. From the total of 1,946 individuals who completed the experiments, we excluded 640 (33%) who failed either of two manipulation check questions. The characteristics of the individuals who failed the manipulation checks did not differ in any statistically significant ways from the characteristics of those who successfully completed these checks and comprised our final sample, with the exception that the latter were slightly older than the former (mean age 39 vs. 37 years, P = 0.02). Demographic characteristics were similar across both experiments. 1Participants who indicated that they did not have health insurance or were unsure whether they had a high-deductible health plan were considered to not have a high-deductible health plan. 2Participants who indicated that they did not have prescription drug coverage or were unsure whether they had prescription drug coverage were considered to not have prescription drug coverage.
