An experiment designed to study the relationship between moral behavior and level of moral development is described. Subjects in the experiment were faced with the choice of either remaining uninvolved observers or intervening to help another student. Their choice was affected by the presence of an authority figure which discouraged any intervention. The results indicated that people at almost all levels of moral development do not help someone in need, although they think that person should be helped. The most common reason was the presence of the authority figure. Only at level 6 of the Kohlberg moral development scale did every subject go against the authority figure and help the student. However, the analysis of behavior at stages 1-5 reveals that an increasing percentage at each level defied authority in order to help the student. Thus the results confirm Kohlberg's theory that moral judgment predicts moral behavior in a situation by determining the interpretation of the situation and consequently the response to it.
