CONCEPT
Silent Redesign of Human Capability
The gradual, invisible atrophy of cognitive skills that occurs when capabilities distributed across a human-AI coupling cease to be exercised by the human component — a design consequence Norman's framework predicts but current AI systems do nothing to prevent.
Chapter 6 of the Norman volume names a phenomenon Norman's earlier work anticipated: when cognitive work is distributed across a person and a tool, the components of the person's capability that are handled by the tool can atrophy from disuse. The distributed system remains spectacularly capable. The person inside it grows quietly diminished. The redesign is silent because it is gradual — each day's experience is nearly identical to the previous day's, so the user does not notice the change — and because it is not a design choice anyone announced. It is a consequence of design choices made for other reasons, manifesting on a timescale that evades organizational measurement and individual awareness.

Norman recognized decades before the AI era that human cognitive capability is not contained solely within the skull. It is distributed across the person, her tools, and her environment.
