Doris, a prominent figure in moral psychology, synthesizes decades of interdisciplinary research to argue that human behavior is often more situational than character-based. He utilizes empirical data from psychology to reframe how philosophers and social scientists understand the consistency of moral action.

Experts recognize this work as a significant contribution to the field of moral psychology, often citing it for its rigorous integration of empirical evidence into philosophical discourse.
