Partial connectivity increases cultural accumulation within groups
Open accessAbstract
Significance: The remarkable ecological success of the human species has been attributed to our capacity to overcome environmental challenges through the development of complex technologies. Complex technologies are typically beyond the inventive capacities of individuals and result from a population process by which innovations are gradually added to existing cultural traits across many generations. Recent work suggests that a population’s ability to develop technologies is positively affected by its size and connectedness. Here, we present an experiment demonstrating that partially connected groups produce more diverse and complex cultural traits than fully connected groups. This result suggests that changes in patterns of interaction between human groups may have created propitious conditions for the emergence of complex cultural repertoires in our evolutionary past.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“spatial heterogeneity enforces isolation and, therefore, diversity within a population, while adaptability ensures that environmental barriers can be crossed and solutions spread, causing an intensification of NC (Cantor and Whitehead, 2013;Derex and Boyd, 2016;Nisioti et al., 2022).”

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.
