Epistemic architecture

Epistemic architecture is the structural design of how knowledge is produced, distributed, validated, and preserved within a system. It is not merely a matter of having information available, but of how that information is routed — who can access it, under what conditions, and with what capacity to act upon it. The term extends from Cognitive engineering and Feedback topology to describe the cognitive infrastructure of any system that must know about itself in order to function.

The Air France Flight 447 accident is a paradigmatic case of epistemic architecture failure: the pilots did not know what the automation had been doing because the cockpit's information design routed the automation's state history into a black box, not into a format that supported human model revision. The system had the information, but the architecture did not transmit it. Epistemic architecture is therefore a design problem, not a training problem: no amount of pilot skill can compensate for a system that structurally withholds the knowledge its operators need.

The concept connects to knowledge representation — the formal structures by which information is encoded — but epistemic architecture is broader: it includes the social, organizational, and technological channels through which knowledge moves, not merely the formats in which it is stored. A system with good epistemic architecture is one in which the right person knows the right thing at the right time and has the authority to act on it. Most systems fail on at least one of these three conditions.
