A peer-reviewed literature source reports that while general mental ability and decision-making competence (as a form of predictive or performance ability) are theoretically distinct, they are largely indistinguishable empirically, refuting the claim that they are empirically distinct.
Decision-making competence (DMC) has potential utility in incrementally predicting decision-making behavior relative to general mental ability (g). However, prior research presents an incomplete depiction of the degree to which these two constructs overlap. This paper evaluated both theoretical and empirical discriminant validity evidence for DMC. Theoretically, DMC and g are distinct constructs though highly interconnected; both constructs exist within the intelligence nomological network. However, empirical findings demonstrate scores on the Adult-Decision Making Competence assessment, are largely indistinguishable from g. Future research should treat DMC an acquired skill as opposed to an underlying individual difference.
