Among the results of recent investigation of epistemic intuitions by experimental philosophers is the finding that epistemic intuitions show cultural variability between subjects of Western, East Asian and Indian Sub-continent origins. In this paper I ask whether the finding of this variation is evidence of cross-cultural variation in the folk-epistemological competences that give rise to these intuitions—in particular whether there is evidence of variation in subjects’ explicit or implicit theories of knowledge. I argue that positing cross-cultural variation in subjects’ implicit (...) theories of knowledge is not the only possible explanation of the intuitions, and I suggest other explanations, including the hypothesis that each subject’s implicit theory of knowledge might contain a heterogeneous set of heuristics for ascribing knowledge. Variation in intuitions, then, might be the result of within-subject heterogeneity rather than across-subject heterogeneity. (shrink)
