 The distinction between these projects has proven helpful within metaphilosophical work on the significance of experimental philosophy, but it should be noted that the metaphilosophical distinction between these three projects does not correspond in any straightforward way to the distinctions between the different concrete research programs experimental philosophers pursue (on free will intuitions, on moral intuitions, on epistemic intuitions, etc.). Each of these concrete research programs can be relevant to a number of different projects, and indeed, it often happens that a single paper reports a result that seems relevant to more than one of these projects. Thus, as we review the actual experimental research coming out of experimental philosophy, we will need to turn away from the metaphilosophical distinction between projects and turn instead to distinctions between concrete research topics.
