# Acquiring moral norms: affect, testimony, learning, and the nativist debate

This is a Stanford Encyclopedia survey of empirical and theoretical work on how humans acquire moral norms (affective/cognitive precursors, testimony, associative and statistical learning, nativism, moralization); the ideamorphism framework's apparatus (emitter, codex, wave, diffraction, ouverture) targets a wholly different object — the transmission and reception of authored creative works — and no proposition here can be tested against this source without inventing a mapping the text does not support.

## Context

### Declined — `no-purchase` [@source]

### Propositional grid [@p31]

> **Read this grid.** “Not evaluated” does **not** mean the source has nothing to say about that proposition. It means **the reading did not instruct it**. That is not a result, and it counts in no denominator. A silence, by contrast, is a finding: the reading touched the proposition without concluding, or noted its absence itself.

**Not evaluated (37)** — P1, P2, P3, P3a, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P14a, P14b, P15, P16, P16a, P17, P18, P18a, P19, P19a, P20, P21, P22, P23, P24, P25, P26, P27, P28, P29, P30, P31

*Overall verdict: **DECLINED:no-purchase** — taxonomy of the August 2026 pass, predating the move to relational verdicts. Kept as metadata: the gap between the two forms is data, not residue. This reading’s judgement is in the grid above.*
