The intelligence test used in our study is essentially a test of fluid intelligence.
“However, while education is primarily expected to influence crystallized intelligence, the intelligence test used in our study is essentially a test of fluid intelligence [18, 19] and the observed high correlations between education and intelligence are therefore remarkable.”

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.
