attention
Your focus on a weapon blinds you to everything else.
When a weapon is present during a crime, witnesses remember fewer details about the perpetrator and the scene.
The presence of a threatening object narrows your visual attention, consuming the cognitive resources usually reserved for processing surrounding context. Experiments show this effect persists even when the 'weapon' is a benign object that creates surprise. You fail to see the context because you are fixated on the threat.
Your attention system is designed to lock onto danger, not accuracy.
