Moral intelligence is grounded in emotion and reason. Neuroscientific and clinical research illustrate how early life co-regulation with caregivers influences emotion, cognition, and moral character. Triune ethics theory (Narvaez, 2008) integrates neuroscientific, evolutionary, and developmental findings to explain differences in moral functioning, identifying security, engagement, and imagination ethics that can be dispositionally fostered by experience during sensitive periods, but also situationally triggered. Mature moral functioning relies on the integration of emotion, intuition, and reasoning, which come together in adaptive ethical expertise. Moral expertise can be cultivated in organizations using the integrative ethical education model.
