David B. Kohlberg

David B. Kohlberg was a renowned American psychologist best known for his work on moral development. He studied how individuals' understanding of justice and ethical principles evolve as they grow older. Kohlberg proposed a stage theory, outlining six levels of moral reasoning—from basic obedience to abstract principles of justice—demonstrating how people's thinking about right and wrong becomes more sophisticated over time. His research has influenced education, law, and psychology by providing insight into how moral judgments develop, helping educators and professionals foster ethical decision-making.
