Street light interference, or SLI, is a phenomenon where people inadvertantly trip the daylight sensors on daylight-sensing light fixtures. People who experience this phenomenon notice it occurring on certain lights- for example, in a parking lot with over a dozen light fixtures, there may be one that will turn on and off when the subject is close to it. This particular light fixture will act strangley, while every other one in the parking lot will remain on.
This phenomenon is similar to psychokinesis, however, one major tenent of it is that the subject cannot control it. Many SLIders (as the subjects are called) do report that the phenomenon occurs more frequently when they are in a heightened emotional state.
Much of the research in this area can be attributed to Hilary Evans, who authored a book, The SLI Effect. The causes of this phenomenon have yet to be determined; however, surveying has created a statistical analysis of what the phenomenon encompasses.
Critics usually attribute the phenomenon to two things. First, the lights are simply shutting off for explainable reasons- for example, sodium vapor type lamps will blink on and off when they start to fail, as they have experience voltage spikes. Second, due to observer bias, the SLIder notices the light turning off (or on), while they pay no attention to lights that are operating normally. SLIders have attempted to rebuke these through demonstration; however, as yet, no one has been able to cause interference during a demonstration.
