Interruption

An interruption is the forced reallocation of attention from the current operation to an incoming signal.

The system was designed to interrupt. The attention-capture mechanism exists because the organism needed to be able to redirect processing instantly when a higher-priority signal arrived — a threat, a sudden change, a social demand. The system that could not be interrupted was the system that missed the predator because it was focused on the task.

In the modern environment, the interruption mechanism fires at a frequency the hardware was never designed for. Notifications, messages, ambient noise, other people’s demands, the mind’s own intrusions — the attention system is being pulled from its current allocation dozens or hundreds of times per day. Each interruption is small. The cumulative cost is not.

The cost of interruption is not just the time lost to the interrupting stimulus. It is the reloading cost — the processing time required to return the attention system to its previous state after the interruption has been handled. The Focus entry covers this mechanism. The system does not return to its prior processing state instantly. It takes time to reload the context, re-engage the depth, and resume the operation. Each interruption pays this cost.

The operator’s leverage: control the incoming signal. The system will respond to whatever arrives — it was designed to. The one at the controls can manage what is allowed to arrive during operations that require sustained attention. Not through willpower (the attention-capture system is faster than the conscious override) but through environment — reducing the signals that fire the interruption mechanism before they reach the system.

Protect the bandwidth. The system can’t do it for itself.
