But the preoperational stage also comes with well-documented limitations: egocentrism, centration, static reasoning, and an inability to mentally...

Carol Gilligan’s Ethics of Care: Why Kohlberg’s Moral Stages Got Women Wrong

Gilligan’s ethics of care emerged as a direct challenge to the most influential model of moral development in psychology — and it permanently changed the field.
