Lawrence Kohlberg’s theory of moral development describes six stages, grouped into three broader levels. He developed the theory from research on how people reason about moral dilemmas.
Level 1 — Pre-conventional morality
Moral decisions are based mainly on personal consequences.
1. Obedience and punishment orientation
“I should do what I’m told because I’ll be punished if I don’t.”
→ Right and wrong are determined by punishment and authority.
2. Individualism and exchange
“What’s in it for me?”
→ A person acts morally when it serves their own interests, often involving an exchange: “You help me, and I’ll help you.”
Level 2 — Conventional morality
Moral decisions are based on social relationships and maintaining society.
3. Good interpersonal relationships
“I want people to think I’m a good person.”
→ Being good means being kind, loyal, helpful and gaining approval from others.
4. Maintaining the social order
“I should follow the rules because society depends on them.”
→ Respect for laws, authority, duties and social order becomes important.
Level 3 — Post-conventional morality
Moral reasoning is based on principles and values that can go beyond existing laws.
5. Social contract and individual rights
“Laws are important, but they should protect people’s rights and can be changed when they are unjust.”
→ Justice, freedom and the welfare of society are emphasized.
6. Universal ethical principles
“I should act according to fundamental principles of justice and human dignity, even if that conflicts with a law or social expectation.”
→ Moral decisions are guided by deeply held universal principles such as justice, equality and respect for human beings.
The progression in one line
Punishment → Self-interest → Approval → Law/order → Rights → Universal principles
An important point is that Kohlberg was describing stages of moral reasoning, not simply whether someone behaves morally. A person can behave correctly for very different reasons.
Also, Stage 6 was extremely rare in Kohlberg’s research, and the later empirical status of the highest stages has been debated.
