 One approach is inspired by the “cognitive-affective personality system” (the so-called CAPS model) that has been developed by social and cognitive psychologists. Rather than looking for empirical evidence of robust traits in behavioral regularities across different types of situations, the CAPS model (and philosophers impressed by this model) focus on the importance of how agents understand the situations they are in. The model views the structure of personality as the organization of relationships among “cognitive-affective units”. These units are clusters of dispositions to feel, desire, believe, and plan that, once activated, cause various thoughts, feelings, and behavior to be formed. Philosophers who ground their understanding of virtue in this type of psychological theory extend the CAPS model to cover robust virtuous traits of character. These traits are viewed as enduring dispositions that include the appropriate clusters of thinking (practical reason), desire, and feeling, manifested in cross-situational behavior.
