In order for them to be directly related as you suggest, all high-iq participants need to memorize lots of facts and learn lots of skills and no low-iq participants can do similarly. It seems that, by citing them as separate factors, the authors are saying this is not true for the population they considered.

- mcguire 10y agoTable 2 shows the pairwise correlations. The highest is between iq and achievement: 0.4-0.7 on different datasets. The correlation between iq and grades is between 0.1 and 0.5. That's strong, but not 1.
