Who's Afraid of Cognitive Diversity?

The Challenge from Cognitive Diversity (CCD) states that demography-specific intuitions are unsuited to play evidential roles in philosophy. The CCD attracted much attention in recent years, in great part due to the launch of an international research effort to test for demographic variation in philosophical intuitions. In the wake of these international studies the CCD may prove revolutionary. For, if these studies uncover demographic differences in intuitions, then in line with the CCD there would be a good reason to challenge philosophical views that rely on those intuitions for evidential support. I argue that philosophical views that rely on demography-specific intuitions for evidential support need not be threatened by such findings. I first provide a detailed analysis of the epistemological principles driving the CCD and distinguish three formulations of this challenge. I then show that there are good reasons to reject all such formulations of the CCD.
