LIT-499: Moral Foundations Theory: The Pragmatic Validity of Moral Pluralism

StatusActive — read in full 2026-10-02 (NOTE-396); worth reading as the full statement of Moral Foundations Theory and as the text to check morality-as-cooperation's comparison against. It states the theory's four claims (nativism, cultural learning, intuitionism, pluralism), reviews a decade of MFQ findings, mostly on political ideology, and offers five criteria for what counts as a foundation. By its own table the Care foundation rests on kin selection and Fairness on Trivers' reciprocal altruism, and Ownership/theft is already a named candidate, so the claim that MFT omits kin altruism, reciprocal altruism and property does not survive this text. Sanctity, the foundation morality-as-cooperation excludes, is by the same table the one with the least evidence of innate preparedness.

Standing in the record

Filed on 2026-10-02 in the morality-as-cooperation batch (ADR-018), as the main statement of the theory morality-as-cooperation defines itself against. It extends Haidt and Joseph’s founding essay, LIT-502, from four modules to five foundations and adds criteria for adding more, and the MFQ-2 paper, LIT-500, extends it in turn by splitting Fairness. No anthology topic holds it, and it carries no instruction for machine-learning practice.

The comparison with morality-as-cooperation. LIT-047 (read in NOTE-034, claim C7) argues that MAC is broader and more precise than MFT, because MFT has no foundation for kin altruism, reciprocal altruism, hawkish displays or property, and includes Care and Sanctity, which are tied to no type of cooperation. Checked against this chapter, NOTE-396 finds:

  • Kin and reciprocity: the omission claim fails. Table 2.4 gives Care’s evolutionary model as kin selection (Hamilton 1964) and attachment, and Fairness’s as reciprocal altruism (Trivers 1971). The text calls the Fairness foundation “largely just an elaboration of the psychology described by Trivers” (p. 114). The narrower charge in LIT-047’s footnote 1 holds better: MFT folds reciprocity and fairness into one foundation, and the chapter itself reports that its fairness measures “centered on equality rather than equity” (p. 106).
  • Property: named, not omitted. Ownership/theft is one of three candidates the chapter calls “good candidates for foundationhood” (p. 104). It is not one of the five and has no measure.
  • Bravery: omitted. No foundation or candidate covers it.
  • Sanctity: the real disagreement. The chapter grounds Sanctity in disgust and the behavioural immune system, not cooperation, as LIT-047 says. It also reports Sanctity as the strongest predictor of attitudes on most culture-war issues (p. 88), so it is evidence that purity is moralized, the point Bloom’s commentary pressed. By MFT’s own criteria it is the weakest foundation: no evidence of it in nonhuman primates or infants (Table 2.4).
  • “Ad hoc”. The chapter answers the charge that its list is arbitrary with five explicit criteria, and says it “engaged in no post hoc evolutionary theorizing” (p. 113). The criteria test candidates; they do not generate them, as game theory does for MAC.

So on this text, “more precise” survives in one sense: MAC derives its list from a model and MFT does not. “Broader” does not survive. Each list has items the other lacks: MFT has Sanctity, care beyond kin, and Liberty as a candidate; MAC has bravery and a property domain.

The chapter also treats two other rivals in this batch. It classes Baumard, André and Sperber’s mutualism (LIT-508) and Gray’s dyadic harm (the line of LIT-494) as monisms that cannot explain disgust’s effects on judgment. It treats Rai and Fiske’s relationship regulation (LIT-507) as compatible with MFT.

NOTE-396 is the close reading of 2026-10-02, and it placed the work: Active. It is the place to read MFT as a theory rather than a questionnaire. Its empirical half is a review of the authors’ and others’ MFQ studies, largely of Western internet samples, which the chapter itself says are probably WEIRD (p. 92).
