Definition

The set of conditions that cause the operator to not see, or not see clearly enough, to make the right perspective or perception decision. The read is running through attentional filters set before the operator walked in: the last conversation he had, the last number he saw, the most dramatic thing that happened this week, and the first assumption he formed about what is going on.

Explanation

This names why two operators looking at the same building can walk away with completely different reads — neither is lying, both are filtering through whatever primed their attention before they ever stepped through the door. The dramatic incident from Tuesday colors Wednesday’s read even if Wednesday’s actual signals point somewhere else entirely.

This is upstream of [Pipeline Failures] — before the aggregation pipeline can fail at any of its five stages, the input itself is already distorted by whatever filter the operator brought in the door. Naming the filters doesn’t eliminate them, but it gives the operator something to check the read against before trusting it.
