Religion and expanding the cooperative sphere in<i>Kastom</i>and Christian villages on Tanna, Vanuatu
Bibliographic record
Abstract
The coexistence of Christian and traditional “Kastom” beliefs on the island of Tanna in Vanuatu provides an especially interesting environment in which to investigate the association between religion and cooperation. Here I use an experimental economic game together with ethnographic and survey data to compare religious beliefs and practices and their association with cooperative behavior across two communities – one predominantly Christian and one predominantly Kastom. Results show some evidence of bias in favor of the self in the Kastom but not the Christian village, although the overall allocations are not significantly different between villages. Allocations to self or own village were generally lower for those who professed belief in a more omniscient and rewarding supernatural agent and for those who engaged in ritual acts of devotion more frequently, although the relationship with ritual devotion and local garden spirit beliefs varied across sites. These findings highlight intriguing differences between the two sites and provide some support for the hypothesis that elements of religion may function to facilitate the expansion of cooperation to co-religionists beyond the local community.

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.
