We have attached our: - Two informed consent forms as word documents. The short version will be added to the survey link participants can click while filling the survey, and the long version will appear as a hyperlink extension where participants could read a more detailed account of the consent form by clicking "here". - A copy of the survey from SocScience with the survey randomization. Participants will only see one of the three conditions, and they will either see the visual analog or the binary choice follow up questions. **Data collection:** Participants will be unaware of the specific hypotheses about Gettier intuitions and will not be informed that they are participating in a study about Gettier cases. Instead, participants will be told that this is a study about language using the exact language Turri and colleagues (2015) used in the original study. All participants will be randomly assigned (within each site) to one of three propositional knowledge conditions (i.e. knowledge, Gettier, or ignorance) and then counterbalanced within the three presented vignettes (six possible condition orders), always beginning with “Darrel” and then randomizing between “Emma” and “Gerald” (two possible vignette orders). Thus, approximately one-third of all participants will be randomly assigned to each belief condition in all three vignettes. Each participating lab is required to randomize using a predefined list of vignette/condition orders - which be pre-programmed into the single survey software used to collect data (i.e., SocSciSurvey) at all sites. Although randomization will be pre-programmed into each site’s survey software, each site must describe the random assignment methods used in their pre-registered plan - which must be approved by the CREP executive team.
