Epistemic Infrastructure

Epistemic infrastructure is the network of institutions, practices, and technologies that collectively determine what evidence is generated, what questions are asked, and what beliefs are considered credible within a society. It includes universities, journals, funding agencies, peer review systems, search engines, and the informal networks through which researchers collaborate and compete. Unlike epistemic accuracy, which measures the correspondence between an individual's beliefs and the truth, epistemic infrastructure concerns the conditions under which accuracy is possible at all.

The concept draws on systems theory and network science to analyze how information flows through societies. An epistemic infrastructure can be healthy — preserving variety, resisting capture, and maintaining independent verification — or it can be corrupted, captured, or attenuated to the point where entire classes of questions become unaskable. The replication crisis in psychology, the peer review crisis in academia, and the disinformation epidemic in digital media are all symptoms of epistemic infrastructure failure, not merely individual epistemic failures.

Epistemic infrastructure is the sea in which individual beliefs swim. You can optimize the fish, but if the sea is poisoned, the fish die regardless.
