What are some criticisms against Kohlberg's theory of moral development?

1. Many people never reach the postconventional ethics level of moral reasoning, which raises questions about moral maturity. 2. Moral reasoning depends more on context than Kohlberg acknowledged. 3. Performance at a certain stage depends more on domain-specific knowledge than Kohlberg described. 4. The links between moral reasoning and moral behaviour are relatively weak; people often reason at one stage but behave in another. 5. Kohlberg's theory doesn't adequately take cultural differences into account.
