      GWAS studies have been done on raw IQ with some degree of success to date. Educational attainment is a somewhat indirect metric since some coursework is much more challenging than other options.https://twitter.com/gwern/status/1021415810928201729?s=19 …

      As far as predictive value is concerned, SAT scores are roughly 0.87 correlated with IQ, and do have predictive value in estimating 1st-year undergraduate GPA even when controlling for high school GPA-- https://collegereadiness.collegeboard.org/pdf/redesigned-sat-pilot-predictive-validity-study-first-look.pdf …

      Unsurprising with first year performance, testing much the same knowledge already learned at high school. Correlations with final year much lower, e.g. https://www.researchgate.net/publication/221849821_Psychological …... Largely disappearing after that. And correlations not causes. All very murky.

      I don't think so. The real reason is that freshman year coursework is more similar between students. After freshman year, students diverge into their respective majors, some of which are *vastly* more difficult than others.

      Self-selection by cognitive skills eliminates the role of cognitive skills in predicting performance relative to the resulting similarly-skilled competing cohort.

          Thanks – but amazed how scholars can take such nebulous measures as if blood tests. I don’t see how any of these (mostly low) correlations distinguish learning ability from ability/knowledge learned (laced with motivation, self efficacy beliefs etc.)

          Education does slightly increase IQ, to your second point, but most of the environmentally-explained proportion of variance in IQ does not appear to be due to education.
