Abstract

This archive contains the data, source records, analysis code, verification materials, and supplementary documentation for a controlled evaluation of a Moral Reasoning Retrieval-Augmented Generation (RAG) intervention. The study compared the same underlying language model under two conditions: an unaugmented Raw API condition and a Moral Reasoning RAG condition. The evaluation dataset contained 300 moral-reasoning questions drawn from established benchmarks, published benchmark frameworks, and researcher-created reliability scenarios. Each matched Raw API and RAG response pair was evaluated under blinded A/B presentation by three AI evaluators, producing 900 judge–question evaluation records and 1,800 individually scored responses. The archive includes: the complete 300-question provenance record and study condition key; original evaluator-result packages; batch-load and model-export records; blinded and decoded canonical analytic datasets; data-cleaning and reconstruction documentation; the Universal AI Moral Reasoning Grading Protocol; executable Python statistical-analysis code; machine-readable statistical outputs; verification records and reproduced figures; exploratory response-length and sensitivity analyses; a cluster-robust sensitivity analysis accounting for the 12 five-stage Multi-step Moral Dilemma sequences represented among the 60 MMD items; and a blind-review recalculation package designed to permit independent statistical verification of the reported results.…
