Validation of the Moral Foundations Questionnaire-2 in the Turkish Context: Exploring Its Relationship With Moral Behavior

Abstract

Despite the considerable attention it has received, Moral Foundations Theory (MFT) remains open to criticisms regarding failure to conceptualize the moral domain. MFT was revised in response to these criticisms, along with its measurement tool, the Moral Foundations Questionnaire (MFQ-2). However, the validity of this revised theoretical structure and its explanatory power relative to existing alternatives, such as Morality as Cooperation Theory (MAC), has not yet been independently tested. Here we first validated MFT's revised six-factor structure using the MFQ-2 in a large quasi-representative sample (N = 1099) from a predominantly Muslim country (i.e., T & uuml;rkiye) and then explored the relationship of these six factors with incentivized measures of moral behavior as well as different psychological variables. Our tests revealed excellent fit values for the six-factor structure proposed by the MFQ-2, which explained more of the variance in criterion variables compared to the MAC Questionnaire (MAC-Q). However, MAC-Q performed better in predicting actual moral behavior (e.g., generosity and cooperation) compared with MFQ-2. Taken together, these findings indicate that, at least for the time being, MFQ-2 and the structure of the moral foundations proposed by MFT can be used to conceptualize the moral domain, but its relatively weak relationship to actual moral behavior limits its insights.
