The evidence that blue light is bad for sleep is much worse from an experimental standpoint than the evidence that it improves cognition and reaction time, which are obviously rather important considerations in street lights.

This is despite them just being clear glass with no appreciable filter effect on visible light.

They interviewed the participants after and the majority on the side with MSG had symptoms. The only problem was that no one had consumed MSG. going off of memory from something I saw a decade ago
