Moral psychology is a field of study in both
philosophy and
psychology. Historically, psychologists interested in moral psychology have carried out
empirical research on the ways in which people make decisions about issues that raise moral concerns. For example, the psychologist
Lawrence Kohlberg questioned boys and young men about their thought processes when they were faced with a
moral dilemma. In contrast, philosophers historically tended to ignore the results of empirical reseach and study theoretical issues to do with ethics, action and psychology. When
Plato, in
The Republic, asked questions about what could motivate a person to act morally, he was asking a questions about moral psychology. Since the late twentieth century, many philosophers working on moral psychology have taken the results of research in psychology and neuroscience seriously, and some psychologists working in this area have considered the philosophical assumptions that lie behind their work.
