 The second project, “the verification project,” aims to determine if the various propositions which philosophers allege to be intuitive, pre-theoretical, or “part of common sense” are, in fact, intuitive to ordinary non-philosophers. This project is motivated both by the general conviction that empirical claims, such as those regarding the extent to which some belief or intuition is shared by others, require adequate empirical support, and by the suspicion that what philosophers find intuitive or regard as commonsensical may be the result of their specialized training, theoretical allegiance, or general cognitive biases (Nadelhoffer and Nahmias 2007: 125; Knobe and Nichols 2008: 9). An example of this approach can be found in Nahmias and colleagues’ investigations of free will (2006, 2007).
