Experiments on contextualism and interest relative invariantism

The research project of common sense or folk behavior for the specific purposes of advancing epistemology has quickly become one of the largest in experimental philosophy. This chapter explains some of this work as it relates to two positions in epistemology: contextualism and interest relative invariantism (IRI). Naturally, questions arise about the relevance of folk behavior to debates in epistemology. First, there is the dialectical issue concerning the extent to which epistemologists have in fact relied on ordinary behavior in defending their theories. Second, in the cases where epistemologists have made such appeals, people can ask if they have been correct in doing so. And third, assuming correctness in this regard, there is a question about which experimental methods, if any, are pertinent for understanding folk behavior. It is taken takes for granted that epistemologists appeal to ordinary usage and that their doing so in fact informs epistemology.
