Abstract
This entry provides an opinionated overview of key epistemological debates regarding experts. To comprehend, justify, and enhance our practices of trusting, utilising, and depending on experts' judgments, it is crucial to clarify the characteristics of experts and the means of identifying those who exemplify them. Consequently, this entry examines and evaluates accounts of the main characteristics of experts. Furthermore, it discusses indicators of experts that help recognise experts and considers to what extent they are accessible to other experts and laypersons.
