The problem with experts

Or in lay terms:

The Problem of Epistocratic Identification and the (Possibly) Dysfunctional Division of Epistemic Labor

How can political actors identify which putative expert is truly expert, given that any putative expert may be wrong about a given policy question; given that experts may therefore disagree with one another; and given that other members of the polity, being non-expert, can neither reliably adjudicate inter-expert disagreement nor detect when a consensus of experts is misguided? This would not be an important question if the problems dealt with by politics were usually simple ones, in the sense that the answer to them is self-evident. But to the extent that political problems are complex, expertise is required to answer them—although if such expertise exists, we are unlikely to know who has it.

Well, luckily there are some real experts.
