摘要：Fay et al. (1) suggest that larger populations do not enhance cumulative cultural evolution (CCE), as working memory becomes taxed while consciously processing additional social models. This decrease in working memory leads to a reduction in high-fidelity copying. Results from a large study ( n = 543) are largely consistent with these interpretations. They further suggest that only under certain circumstances might larger population sizes lead to enhanced CCE. However, the circumstances that might lead to such an effect seem to be common ones. The chosen methodological approach restricted known biases from being employed, but biases.
