There are several different results. Language aptitude was the best predictor for learning rate. Fluid intelligence was the best predictor for programming accuracy (the numbers you quote), and for declarative knowledge. But yeah the actual title of this 2020 article is "Relating Natural Language Aptitude to Individual Differences in Learning Programming Languages", the current HN title "Predictor of learning to code is language aptitude - not math/cognitive ability" doesn't appear in the article, and I don't see at all how it is supported (besides numeracy specifically not showing up strongly) when they found general cognitive ability to be a significant predictor.
