research_objective: "Refine the design of context shifting experiments and test whether context (Low vs High) affects truth-value judgments for knowledge ascriptions (and other expressions) across all four polarity×context cells."

notes: "A local copy of the supplementary Analyses-SHARE archive is stored under out/external and contains raw response files plus the original R analysis scripts."

One participant reported that he was a native speaker of Spanish and was excluded from subsequent analyses. The 39 participants included in the analyses reported to be native speakers of English."

- scenario_code: bridge
scenario_type: "Truck convoy / bridge-crossing vignette with testimonial evidence about prior trucks."
high_stakes_text: "High context: the bridge spans a yawning thousand-foot drop, and the protagonist worries that the earlier trucks may have weakened it enough that his truck will not make it across."
low_stakes_text: "Low context: the bridge is only over a three-foot ditch; after hearing that all 15 trucks in the caravan made it over safely, the protagonist reasons that his truck will probably make it too."

- scenario_code: train
scenario_type: "Express-train vignette about whether the arriving train is the express to Providence."
high_stakes_text: "High context: Sid and Johnny absolutely need to be in Providence as soon as possible because their career depends on it; Sid warns that if the train is not the express they will miss their meeting, and in the high-error version suggests that the ticket-seller may have misunderstood or been misunderstood."
low_stakes_text: "Low context: Sid and Johnny are travelling to see friends on a relaxing vacation, so it matters only mildly whether the train is the express; Johnny relies on remembering that the ticket-seller said it was the express."
provenance:
page: 30
quote: "Sid and Johnny are at Back Bay Station in Boston preparing to take the commuter rail to Providence. ... Low (stakes): They can take their time getting there---they’re going to see friends.
