Is pupil size (at baseline) related to intelligence? Yes, but not very much. r ≈ .05.pic.twitter.com/xXqmoHPoKq

Maybe unreliable pupil var? What's your regression of pupil size on IQ? 1 SD in IQ -> .45 mm in earlier study.
Read the link and you will see that left eye x right eye is r = .97. @pnin1957 @Kane_WMC_Lab

That seems like a strong indication of unreliability, given how common anisocoria is: https://en.wikipedia.org/wiki/Anisocoria

The unstandardized regression slope would be interesting as measurement error in DV doesn't bias it.

I guess you can examine that when the data comes out. :) It is only intended to showcase the dataset.
@pnin1957@Kane_WMC_Lab -
Okay :) My prediction is that much of the discrepancy b/w your and earlier results may be due to unreliability

Your suggestion fails the reversal test. http://andrewgelman.com/2016/01/26/more-power-posing/ …
@pnin1957@Kane_WMC_Lab -
Not really. Tsukahara's precision seems to be .1 mm, you seem to have 1 mm. Should cause some diffs in corrs.
-
Very slight. Why don't you just simulate data and see? Don't be so lazy.
@pnin1957@Kane_WMC_Lab -
Nah, that sounds like work. Tsukahara had 95% CI .25-.45, so I'd be surprised if there are no moderators.
