 We return now to the basic form of social epistemology, in which individual cognizers seek information from other individuals. Here we are interested not in the concepts of justification or knowledge in general, but in particular applications. This might be called applied social epistemology. For example, how can one identify other individuals as sources of accurate information? A salient type of case is when one seeks information from an “expert,” where the seeker is himself/herself a layperson. Unfortunately, experts don’t always agree with one another. If you are offered advice by two different (putative) experts, but the two advisers disagree, which one should you trust, or believe?
