**Randomization Method**
Participants read three vignettes ("Darrel", "Gerald", and "Emma") presented in random order without replacement. Each vignette was randomly assigned to a belief condition (knowledge control, Gettier case, and ignorance control) and counter-balanced to ensure that each participant experienced all three vignettes and all three belief conditions once. Randomization, condition assignment, and counter-balancing was conducted automatically by the SocSciSurvey system used to administer the survey.
