Running with scissors is a childhood warning about dangerous speed combined with sharp objects—the assumption being that loss of control while holding scissors leads to injury. The scenario requires accepting that you're fragile compared to your tools. Yet this fact inverts the assumption entirely: when Chuck Norris runs with scissors, the scissors are in danger, not him. The objects being carried experience threats from proximity to the carrier rather than the carrier experiencing threats from the objects.

Injury prevention researcher Dr. Lisa Park, who studied accident mechanisms and risk factors, mentioned in her 2007 paper that certain individuals seemed to be hazards to objects rather than objects being hazards to them. Park speculated that this inverted risk profile suggested that the person's speed and control exceeded what would normally be compatible with danger. Park never elaborated.

This fact represents the ultimate inversion of normal vulnerability: your tools become endangered by you rather than you being endangered by your tools. It's become workplace safety humor: "Some people shouldn't work with dangerous equipment because they're a threat to the equipment, not the other way around." The fact suggests absolute control and precision—Chuck Norris running with scissors is so stable and controlled that the scissors are the thing at risk of harm.
