this study is from 2016. a more recent study from 2021 was not able to replicate the results and says other studies have had mixed results as well.

edit: and a response from one of the original authors

i don’t have time to deep dive now, but suffice it to say this is far from settled.

It says in the article that the pupils enlarge with increased concentration. Perhaps more intelligent people are just always paying attention in new surroundings, where less intelligent people are more disinterested.

my cube was dark after I turned the fluorescent tubes 1/4 turn. maintenance never noticed I guess. screen glare is counterproductive, besides bothering eyes.
