Moral rationality and intuition: An exploration of relationships between the Defining Issues Test and the Moral Foundations Questionnaire

Abstract

Explorations of relationships between Haidt’s Moral Foundations Questionnaire (MFQ) and indices of moral decision-making assessed by the Defining Issues Test have been limited to correlational analyses. This study used Harm, Fairness, Ingroup, Authority and Purity to predict overall moral judgment and individual Defining Issues Test-2 (DIT-2) schema scores using responses from 222 undergraduates. Relationships were not confirmed between the separate foundations and the DIT-2 indices. Using the MFQ moral judgment items only, confirmatory factor analyses confirmed higher order constructs called Individualizing and Binding foundations. Structural models using these higher order factors fitted the data well, and findings indicated that the Binding foundations significantly positively predicted Maintaining Norms and negatively predicted both overall moral judgment (N2) and the Postconventional Schema. Neither Individualizing nor Binding foundations significantly predicted Personal Interest. While moral judgments assessed by DIT-2 may not be evoking the MFQ foundations, findings here suggest the MFQ may not be a suitable measure for capturing more advanced moral functioning.
