research_objective: Report evidence-seeking experiments testing whether folk judgments about when an agent knows are sensitive
to practical stakes; discuss implications for interest-relative invariantism (IRI) and contextualism; includes between-subject,
within-subject (juxtaposed), and a stakes × prompt-type study connected to the Reason-Knowledge Principle (RKP).

objective: Test whether participants require more evidence for knowledge (more proofreading) under high vs low stakes in
a typo vignette; includes an additional high-stakes condition where the protagonist is unaware of the stakes (Ignorant-Typo-High).

no one will get an A for the paper if it has a typo. He demands perfection. John, however, finds himself in an unusual
circumstance. He needs an A for this paper to get an A in the class. And he needs an A in the class to keep his scholarship.
Without the scholarship, he can’t stay in school. Leaving college would be devastating for John and his family who have
sacrificed a lot to help John through school. So it turns out that it is extremely important for John that there are
no typos in this paper. And he is well aware of this.'

and it won’t matter if there are a few typos. Nonetheless Peter would like to have no typos at all.'
