Overview

This lecture covers Lawrence Kohlberg's theory of moral development, including his three stages, the methods he used, and critiques of his work.

Morality and Its Definition

  • Morality is our sense of right and wrong.
  • Different cultures and individuals may define morality differently, but some universal principles exist.

Kohlberg’s Research and the Heinz Dilemma

  • Lawrence Kohlberg studied how people reason about moral issues.
  • He used the Heinz Dilemma, a scenario where a man must decide whether to steal a drug he can't afford to save his dying wife.

Kohlberg’s Three Stages of Moral Development

  • Answers to moral dilemmas are classified into three levels: preconventional, conventional, and postconventional.

Preconventional Stage

  • Moral decisions are based on avoiding punishment or gaining rewards.
  • Reasoning is self-centered and does not consider broader ethical implications.

Conventional Stage

  • Decisions are made by conforming to societal norms and seeking social approval.
  • Focus is on law, order, and being viewed positively by others.

Postconventional Stage

  • Individuals use personal principles and universal ethical standards.
  • Moral reasoning may challenge societal norms if they conflict with personal justice convictions.

Criticisms of Kohlberg’s Theory

  • Criticized for gender bias, as Kohlberg's research primarily involved young males.
  • Criticized for cultural bias, as the theory reflects Western values and may not fit collectivist cultures where group values override individual justice.

Key Terms & Definitions

  • Heinz Dilemma — a moral scenario used to study reasoning in moral development.
  • Preconventional Stage — morality based on self-interest and avoiding punishment.
