The five-factor structure of MFT is thought to be universal and rooted in the evolutionary past but the evidence is scarce regarding the stability of this five-factor structure across diverse cultures. We tested this universality argument in a cross-cultural dataset of 30 diverse societies spanning the WEIRD (Western educated industrialized rich democratic) and non-WEIRD cultures by testing measurement invariance of the short-form of the moral foundations questionnaire. The results supported the original conceptualization that there are at least five diverse moralities although loadings of items differ across WEIRD and non-WEIRD cultures. In other words the current research shows for the first time that the five-factor structure of MFT is stable in the WEIRD and non-WEIRD cultures.Englishinfo:eu-repo/semantics/closedAccessMoral foundations questionnaire, Measurement invariance, WEIRD and non-WEIRD cultures, Cross-cultural assessment, Moral psychologyFIT INDEXES, QUESTIONNAIRE, HYPOTHESIS, VALIDATION, VALIDITY, LIBERALS, SETSCross-Cultural AssessmentMoral PsychologyMeasurement InvarianceWEIRD and Non-WEIRD CulturesMoral Foundations QuestionnaireThe five-factor model of the moral foundations theory is stable across WEIRD and non-WEIRD culturesArticle
