SLI is an uncontrollable phenomenon

SLIders do not control the phenomenon

The repetition of the phenomenon raises questions in the person affected by the phenomenon.  The individual wonders if the sightings are purely a coincidence or if their presence is really the cause of the lights going out. So it's a repetitive phenomenon, but one that the person has no control over it. However, the phenomenon is observed so often that one can exclude the simple explanation of a defective light. Also, why would a light bulb fail in the presence of one person and not another.

This unexplained effect on street lights has no bearing on the person, other than raising questions. It does not cause bodily or mental sensations. The person does not feel anxiety or fear. The electrical equipment is not damaged. After the person has passed, the lamp simply turns on again.

Since the SLIder effect is random and out of the person's control. It's not spectacular. It is not brought about on command. So this strange action on street lights is very difficult to study and explain scientifically.
