CONCEPT
The Interrupted Workflow as Functional Brain Damage
Goldberg's provocative diagnostic claim — that chronic interruption produces the same four functional signatures as clinical prefrontal damage (impaired sustained attention, fragmented coordination, degraded creative output, impaired metacognition) despite leaving neural tissue structurally intact.
The claim is deliberately strong. Clinical prefrontal damage produces four consistent functional consequences: impaired sustained attention, fragmented cognitive coordination, degraded creative output marked by stereotypy or irrelevance, and impaired metacognitive self-monitoring. Empirical research on chronically interrupted knowledge workers documents the same four signatures in individuals whose prefrontal cortices are structurally intact. The mechanism differs — structural damage destroys the neural substrate, while chronic interruption prevents the substrate from functioning — but the functional outcome is equivalent. Tissue that is intact but chronically prevented from sustaining the activity patterns its function requires is, for practical purposes, functionally impaired.

The comparison is neurologically defensible rather than rhetorical. Prefrontal coordination depends on sustained firing patterns, oscillatory synchronization between prefrontal and posterior networks, and tonic inhibitory activity. Structural damage destroys the substrate that supports these patterns. Chronic interruption breaks the patterns before they stabilize, disrupts the synchronization
