In their widely cited article, Swain et al. (2008) report data that, purportedly, demonstrates instability of folk epistemic intuitions regarding the famous Truetemp case authored by Keith Lehrer. What they found is a typical example of priming, where presenting one stimulus before presenting another stimulus affects the way the latter is perceived or evaluated. In their experiment, laypersons were less likely to attribute knowledge in the Truetemp case when they first read a scenario describing a clear case of knowledge, and more likely to ascribe knowledge when they first read a vignette describing a clear case of nonknowledge. We tried to replicate Swain et al. findings in three experiments: one devised in Polish, and the other two conducted in English. We found no priming effect for knowledge ratings regarding the Truetemp case – laypersons were similarly likely to attribute knowledge in all three investigated conditions (primed with a clear case of knowledge, primed with a clear case of nonknowledge, and not primed). These three failed replication attempts are not decisive as to whether the priming effect in question occurs, nevertheless, the collected data puts Swain et al. conclusions about instability of epistemic intuitions in jeopardy.

The possibility of knowledge attributions across contexts (where attributor and subject find themselves in different epistemic contexts) can create serious problems for certain views of knowledge. Amongst such views is subject-sensitive invariantism—the view that knowledge is determined not only by epistemic factors (belief, truth, evidence, etc.), but also by non-epistemic factors (practical interests, etc.). I argue that subject-sensitive invariantism either runs into a contradiction or has to make very implausible assumptions. The problem has been very much neglected but is so serious that one should look for alternative accounts of knowledge.
