Researchers have primarily tested the predictions of the social intelligence hypothesis with larger-scale comparative analyses in which an anatomical proxy for cognitive ability (e.g., relative brain size) is related to a social feature.
“Consequently, researchers have primarily tested the predictions of the social intelligence hypothesis with larger-scale comparative analyses in which an anatomical proxy for cognitive ability (e.g., relative brain size) is related to a social feature (e.g., Barton 1996; Lefebvre et al. 1997; Dunbar 1998a; Reader and Laland 2002; Isler and van Schaik 2009).”

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.
