Longitudinal studies demonstrate that early intelligence test scores predict later educational attainment.
“Longitudinal studies demonstrate the predictive power of early intelligence test scores for later educational attainment (Deary, Strand, Smith, & Fernandes, 2007;Roth et al., 2015).”
From How Much Does Education Improve Intelligence? A Meta-Analysis (2018) · cites this paper as Roth et al., 2015
The indexed 2015 Intelligence record (pp. 118–137) reports a correlation between standardized intelligence tests and school grades, supporting a general link with scholastic achievement. It does not establish that early scores predict later educational attainment in longitudinal studies; grades and educational attainment are different outcomes. (LLM, conf=0.82)
Experimental — accuracy not yet measuredThe relationship between the ideal L2 self and achievement is smaller than the magnitude that aptitude (r = .49, Li, 2016) and intelligence (r = .54, Roth et al., 2015) explain in academic achievement.
“It is also smaller than the magnitude that aptitude (r = .49,Li, 2016) and intelligence (r = .54,Roth et al., 2015) explain in academic achievement, two established individual difference variables.”
From The L2 motivational self system: A meta-analysis (2018) · cites this paper as Roth et al., 2015
The indexed record for Roth et al. (2015, pp. 118–137) gives .54 in an abstract, but the record also says “No full text” and “No document available.” Because the available passages contain no paper-text results section, the cited intelligence–achievement correlation cannot be verified under the requirement to use the paper’s text rather than its abstract (searched: .54, intelligence, school grades, correlation). (LLM, conf=0.70)
Experimental — accuracy not yet measuredThere is ample evidence that pervasive selection processes operate in the intelligence-education association.
“Indeed, there is ample evidence that pervasive selection processes operate in the intelligence-education association: Longitudinal studies demonstrate the predictive power of early intelligence test scores for later educational attainment (Deary, Strand, Smith, & Fernandes, 2007;Roth et al., 2015).”
From How Much Does Education Improve Intelligence? A Meta-Analysis (2018) · cites this paper as Roth et al., 2015
The indexed record for the 2015 article (pp. 118–137) says no full text is available. The retrieved passages do not establish whether Roth et al. report longitudinal evidence that early intelligence scores predict later educational attainment or discuss selection processes; searches for both points returned no passage from the paper’s text. (LLM, conf=0.74)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
