Kohlberg's Stages of Moral Development
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
Formulated by Lawrence Kohlberg in the 1950s and 1960s. Moral reasoning develops through three levels, each with two stages: the pre-conventional level, based on punishment and self-interest; the conventional level, based on social approval and maintaining law and order; and the post-conventional level, based on social contract and universal ethical principles. Progress depends on cognitive development and on encountering reasoning above one's current stage.
SCAFFOLDING EFFECT
Reduce cognitive load
- Read the reasons: identify the stage from the justification rather than from the decision itself - Challenge upward: use dilemmas one stage above the current level to create productive conflict - Design rules: match institutional incentives to the reasoning stage people actually occupy
Anchor fast decisions
Each stage supplies a different criterion for justifying a choice, and a stage is abandoned when it can no longer resolve the conflicts a person meets. Reasoning one level higher accounts for more of the situation, which creates the disequilibrium that drives development. Progress therefore comes from processing better arguments rather than from being told the correct conclusion.
