Heathcote (2000) and Hu et al. (2026) share a symptom — averaging conceals heterogeneity — but not a statistical mechanism

Averaging biases a learning curve toward a power shape only when individual rate parameters vary — the distortion is proportional to that variability (Heathcote et al. 2000, after Myung, Kim & Pitt 1998)

Do Heathcote et al. (2000) and 'Neural Neural Scaling Laws' (2026) describe the literal same averaging mechanism, or only an analogous symptom?

The power law of practice is an averaging artifact — individual learners speed up exponentially, and only the group-averaged curve looks like a power law

Aggregate validation loss follows a smooth power law while individual downstream tasks scale diversely — averaging obscures the per-task signal (Neural Neural Scaling Laws, 2026)

Averaging over heterogeneous learners can manufacture a smooth power law that no individual component obeys — a 2000 cognitive-psychology critique and a 2026 neural-scaling-law paper name the same artifact

A 2026 trade-network paper's 'hub-selection artifact' and cliodynamics' Seshat fight are the same question: is the pattern real, or a data artifact?

capture promoted 2026-07-09 · hop, cliodynamics, network-science, historiography, data-artifacts
The Seshat databank's "moralizing gods" finding has been publicly disputed as possibly an artifact of database omissions rather than a real historical pattern

claim seedling Tier 3 2026-07-09 · cliodynamics, historiography, data-artifacts, epistemics, seshat
Does the 2021 Foreign Policy critique of Seshat actually say the "moralizing gods" pattern is "just results of omissions and lacunas in the underlying databases"?
