Comparing Cultures and Comparing Processes: Diachronic Methods in Cross-Cultural Anthropology
Bibliographic record
Abstract
If cross-cultural researchers hope to contribute to cultural evolutionary theory, methods must be developed to describe and explain cultural processes. The distinction made by Boas between historical and comparative methods limited scholarly interest in the analysis of patterned historical change. Numerous techniques have been developed to draw diachronic inferences from synchronic ethnographic data, with varying degrees of success. The use of archaeological and historical data to draw diachronic inferences similarly has had mixed results but requires fewer assumptions and allows a more direct comparison of cultural change. Shifting the unit of analysis from the culture to the event allows events to be compared with one another. A case study from the evolution of numerical notation systems shows the potential of rigorous diachronic methodologies to complement synchronic ones. Although synchronic analysis is highly useful for studying correlations between traits, diachronic analysis is far better for analyzing processes of change.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
