Moral Foundations Questionnaire
Also known as: MFQ, MFQ-30, Moral Foundations Theory Questionnaire
The Moral Foundations Questionnaire (MFQ) is a 30-item self-report instrument developed by Graham, Haidt and colleagues (2011) to measure the degree to which people rely on five intuitive moral foundations: Care/harm, Fairness/cheating, Loyalty/betrayal, Authority/subversion, and Sanctity/degradation. It is the standard operationalization of Moral Foundations Theory, which argues that political and cultural moral disagreements arise from differing weights placed on these foundations.
Key highlights
- Provides a parsimonious, theory-driven map of moral concerns that predicts political ideology better than single-principle accounts.
- Widely translated and validated, with large reference datasets available through the YourMorals project.
- Distinguishes individualizing from binding morality, clarifying the moral basis of the liberal-conservative divide.
- Useful both as a continuous individual-difference measure and as the basis for experimental moral-framing manipulations.

When to use it
Use the MFQ to characterize the moral intuitions underlying political and cultural attitudes, to explain ideological differences in policy preferences, or to study moral persuasion and message framing. It is well suited to survey research on the moral roots of partisanship, attitudes toward immigration, the environment, and bioethics, and to cross-cultural comparisons of moral priorities. It is descriptive, not normative, and assumes the five-foundation structure travels across the populations studied.
Strengths & limitations
- Provides a parsimonious, theory-driven map of moral concerns that predicts political ideology better than single-principle accounts.
- Widely translated and validated, with large reference datasets available through the YourMorals project.
- Distinguishes individualizing from binding morality, clarifying the moral basis of the liberal-conservative divide.
- Useful both as a continuous individual-difference measure and as the basis for experimental moral-framing manipulations.
- Subscale internal consistencies are often modest, limiting reliability of individual foundation scores.
- The five-factor structure does not always replicate cleanly, especially outside WEIRD samples; some analyses favor two factors.
- The proposed foundation of Liberty/oppression is not in the standard MFQ-30 and requires the extended MFQ.
- Self-reported moral relevance may diverge from moral behavior and from intuitive responses under time pressure.

Frequently asked
What are the five moral foundations measured?
Care/harm (sensitivity to suffering), Fairness/cheating (reciprocity and justice), Loyalty/betrayal (group solidarity), Authority/subversion (respect for legitimate hierarchy), and Sanctity/degradation (purity and disgust). Care and Fairness are termed 'individualizing' foundations; Loyalty, Authority, and Sanctity are termed 'binding' foundations.
Why do the subscales sometimes have low reliability?
Each foundation is measured by only six items spanning two response formats (relevance and judgment), and the foundations are conceptually broad. This yields modest Cronbach's alphas. Researchers often aggregate into the individualizing and binding composites, which are more reliable, or use the longer Moral Foundations Questionnaire-2 (MFQ-2) developed to improve measurement.
Is the MFQ politically biased?
The instrument is descriptive: it measures which moral considerations people treat as relevant, not which are correct. Critics debate whether the foundations are exhaustive or whether some (like Fairness) are operationalized in ways that favor particular ideologies, which is why validation and alternative factor structures remain active areas of study.
