inattentional_blindness
The failure to perceive clearly visible objects or events when attention is engaged elsewhere. Unlike change blindness, which requires a disruption, inattentional blindness occurs even with uninterrupted viewing when cognitive resources are directed toward another task. This demonstrates that attention, not just eye direction, determines what we consciously perceive.
In the famous 'invisible gorilla' experiment, participants counting basketball passes fail to notice a person in a gorilla suit walking through the scene, pausing to beat their chest, even though the gorilla is clearly visible for nine seconds.
A surgeon so focused on a critical step of a procedure fails to notice that the patient monitoring alarm has been quietly sounding for over a minute, a finding that has prompted changes in how operating room alerts are designed.
A driver deeply engaged in a hands-free phone conversation drives past her usual exit on the highway without noticing the large, clearly visible sign — her attention was fully allocated to the conversation, leaving none for peripheral navigation cues.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Was attention heavily focused on a specific task when the unnoticed event occurred?
Type: binaryWas the missed stimulus unexpected in the given context?
Type: binaryWould the stimulus have been noticed without the competing attention demand?

Conscious perception requires attention, not just sensory input. When attentional resources are consumed by a demanding task, stimuli outside the focus of attention may be processed at a sensory level but never reach conscious awareness.
In critical tasks, reduce attentional load and build in redundant monitoring systems. Train people to periodically shift attention from their primary task to scan for unexpected events.
Inattentional blindness contributes to traffic accidents (drivers looking but not seeing motorcycles), industrial accidents, surgical errors, and security failures. It is a fundamental challenge for safety engineering.
