Kohlberg's stages of moral development explain how people's moral reasoning can change as they mature. This cheat sheet helps students compare the three levels and six stages in a clear, organized way. It is useful for studying psychology, ethics, human development, and social behavior.
The focus is on how people justify decisions, not simply whether their actions are right or wrong.
The model is organized into Level 1: Preconventional Morality, Level 2: Conventional Morality, and Level 3: Postconventional Morality. Each level contains two stages, moving from avoiding punishment, to following social rules, to reasoning from broader ethical principles. A key idea is that Kohlberg judged moral development by the reasoning behind a choice.
Students should connect each stage to examples, such as rules, rewards, approval, laws, rights, and justice.
Key Facts
- Kohlberg's theory has 3 levels and 6 stages of moral development.
- Level 1, Preconventional Morality, focuses on personal consequences, such as punishment, rewards, and self-interest.
- Stage 1 is Obedience and Punishment Orientation, where a person sees an action as wrong if it leads to punishment.
- Stage 2 is Individualism and Exchange, where a person makes moral choices based on personal benefit or fair trade.
- Level 2, Conventional Morality, focuses on social approval, relationships, laws, and maintaining social order.
- Stage 3 is Good Interpersonal Relationships, where a person wants to be seen as good, helpful, or loyal by others.
- Stage 4 is Maintaining Social Order, where a person believes laws and rules should be followed to keep society stable.
- Level 3, Postconventional Morality, focuses on social contracts, individual rights, justice, and universal ethical principles.
Vocabulary
- Moral development
- Moral development is the way a person's understanding of right and wrong changes over time.
- Preconventional morality
- Preconventional morality is the level where moral choices are based mainly on punishment, rewards, or personal gain.
- Conventional morality
- Conventional morality is the level where moral choices are based on social approval, laws, duties, and group expectations.
- Postconventional morality
- Postconventional morality is the level where moral choices are based on rights, justice, and ethical principles that may go beyond specific laws.
- Moral dilemma
- A moral dilemma is a situation in which a person must choose between conflicting values, rules, or duties.
- Social contract
- A social contract is the idea that laws are agreements made to protect people's rights and can be changed when they are unjust.
Common Mistakes to Avoid
- Confusing actions with reasoning is a mistake because Kohlberg's stages classify why a person makes a choice, not just what choice they make.
- Assuming older people are always in higher stages is wrong because age may influence moral reasoning, but it does not guarantee postconventional thinking.
- Labeling Stage 4 as blind obedience is inaccurate because this stage values laws and duties mainly for social stability and order.
- Thinking postconventional morality means ignoring all laws is wrong because this level considers rights, justice, and ethical principles, not simple rule-breaking.
- Treating the six stages as personality types is a mistake because they describe patterns of moral reasoning that may vary by situation and context.
Practice Questions
- 1 A student refuses to cheat because they do not want to get detention. Which Kohlberg stage does this best match: Stage 1, 2, 3, 4, 5, or 6?
- 2 A person returns a lost wallet because they want others to think they are honest and kind. Which level number and stage number best fit this reasoning?
- 3 A citizen argues that a law should be changed because it unfairly denies basic rights to one group. Which Kohlberg level is most likely shown, and why?
- 4 Explain why two people could make the same decision in a moral dilemma but still be classified in different Kohlberg stages.
