The weight of declarative knowledge is substantially greater in VCI subtests reflecting Gc than in all other subtests that place little emphasis on declarative knowledge, as illustrated by their lesser decline with age and higher correlation with education and socio-economic levels.
“Still, the weight of declarative knowledge is substantially greater in VCI subtests reflecting Gc, as illustrated by their lesser decline with age (Baxendale, 2011, Grégoire, 1993;Kaufman et al., 1989, Ryan et al., 2000) and their higher correlation with education and socio-economic levels (Dori & Chelune, 2004;Heaton et al., 2003;Holdnack et al., 2013), than all other subtests that place little”

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.
