Cross-cultural tests of Kohlberg's stages found:

1. Kohlberg's theory was tested in several cultures. 2. People went through the stages in the same order. 3. But they did so at different rates. 4. Critics add that the highest stages are not culturally neutral. **Why not the others:** Different orders would contradict the finding. Stage 6 is rare everywhere. Stages cannot be skipped. _Source: Wikipedia, "Lawrence Kohlberg's stages of moral development", section "Cross-cultural generalizability" (revision 1376737595)_
