Expert Judgment: Overlooked Epistemic Reasons

Abstract

When experts make judgments that inform public policy, what kinds of reasons should they consider in order to provide informed and responsible recommendations? Extant discussions of this question typically focus on the role of non-epistemic values in the evaluation of scientific hypotheses. However, the kinds of epistemic reasons that should undergird such assessments have received comparatively little attention. This paper argues that evidence is not the only kind of epistemic reason important for guiding expert judgment. Experts must also be sensitive to two kinds of social epistemic reasons, which have so far been overlooked in discussions on expertise. First, experts must be sensitive to higher-order evidence about other experts' views, including about disagreements between experts. Second, they must also be sensitive to inquisitive reasons concerning, for example, the pursuitworthiness of various research programs in the field, or the distribution of labor across those research programs. The paper illustrates the fruitfulness of this account by showing the importance of these overlooked reasons for understanding examples of expert judgment from the history of science and contemporary scientific practice
