I have a top 1% IQ, so lower than you I guess, and my pupils are also super big. I'm pretty sensitive to light, though not as much as you. I remember multiple people remarking on it to me during my school days, and my eye doctor has never had to dilate my pupils before examination which is a nice bonus.

Yeah, it just seems like its measuring engagement during the testing.

Would have been better to take measurements at "rest" as well, then compare them.

It'd be a lot easier to believe there's a larger increase in pupil size when concentrating than permenantly.

That being said both my parents had blue eyes, and looking at my DNA I should have blue eyes. But they're green, which can be explained by pupil dilation causing an increase in pigment density. Like how David Bowie has one eye that's permanently dilated so looking at a picture it looks like he has heterochromia when he doesnt.

Shits interesting, but there's going to need to be a lot of follow up studies to rule out confounding variables.

Nothing can be concluded from the anecdotal reports of individuals. If there's a real effect here it can only be seen in a statistical study of many subjects (and it seems there's some doubt about the study's replicability). So I don't think anyone could tell you definitively whether your eyes manifested this effect, and it would be a mistake to treat the hypothesis as confirmed or undermined by any one person's report.
