Lawrence Kohlberg's Stages of Moral Development constitute an adaptation of a psychological theory originally conceived of by Swiss psychologist Jean Piaget. Kohlberg, while a Psychology postgraduate student at the University of Chicago, expanded and then developed Piaget’s concepts throughout the course of his life.
The theory holds that moral reasoning, the basis for ethical behaviour, has 6 identifiable
developmental stages, each more adequate at responding to moral dilemmas than its
predecessor. Kohlberg followed the development of moral judgment far beyond the ages
studied earlier by Piaget (1932) who also claimed that logic and morality develop
through constructive stages. Expanding on Piaget's work, Kohlberg (1963) determined
that the process of moral development was principally concerned with justice and
that it continued throughout the individual's lifetime -
Kohlberg’s methodology used the Moral Judgement Interview he had first developed
for his 1958 dissertation with 72 boys aged between 10 and 16, both working class
and middle class in Chicago. During the roughly 2-
A woman was near death from a special kind of cancer. There was one drug that the doctors thought might save her. It was a form of radium that a druggist in the same town had recently discovered. The drug was expensive to make, but the druggist was charging ten times what the drug cost him to produce. He paid $200 for the radium and charged $2,000 for a small dose of the drug. The sick woman's husband, Heinz, went to everyone he knew to borrow the money, but he could only get together about $1,000 which is half of what it cost. He told the druggist that his wife was dying and asked him to sell it cheaper or let him pay later. But the druggist said: "No, I discovered the drug and I'm going to make money from it." So Heinz got desperate and broke into the man's store to steal the drug for his wife.
Should Heinz have broken into the laboratory to steal the drug for his wife? Why or why not?
Kohlberg was interested in how individuals would justify their actions if placed
in such moral dilemmas. He analysed the form of moral reasoning displayed, rather
than its conclusion and classified it as belonging to one of 6 distinct stages generally
grouped into 3 levels of 2 stages each: Pre-
Pre-
The Pre-
In Stage 1 (obedience and punishment driven), individuals focus on the direct consequences of their actions on themselves. For example, an action is perceived as morally wrong because the perpetrator is punished. "The last time I did that I got spanked so I will not do it again." The worse the punishment for the act is, the more ‘bad’ the act is perceived to be. This can give rise to an inference that even innocent victims are guilty in proportion to their suffering. This view is egocentric, lacking recognition that others' points of view are different from one's own. There is a deference to superior power or prestige. Obedience is not valued for its own sake.
Stage 2 (self-
Conventional
The Conventional level of moral reasoning is typical of adolescents and adults. Those who reason in a Conventional way judge the morality of actions by comparing them to society's views and expectations. The views of others are now considered. The Conventional level consists of the third and fourth stages of moral development.
In Stage 3 (interpersonal accord and conformity driven), the self enters society by filling social roles. Individuals are receptive to approval or disapproval from others as it reflects society's accordance with the perceived role. They try to be a ‘good boy’ or ‘good girl’ to live up to these expectations, having learned that there is inherent value in doing so. Stage 3 reasoning may judge the morality of an action by evaluating its consequences in terms of a person's relationships, which now begin to include things like respect, gratitude and the ‘golden rule’ (reciprocity of just treatment). "I want to be liked and thought well of; apparently, not being naughty makes people like me." Desire to maintain rules and authority exists only to further support these social roles. The intentions of actions play a more significant role in reasoning at this stage; "they mean well ...".
In Stage 4 (authority and social order obedience driven), it is important to obey
laws, dictums and social conventions because of their importance in maintaining a
functioning society. Moral reasoning in Stage 4 is thus beyond the need for individual
approval exhibited in Stage 3; society must learn to transcend individual needs.
A central ideal or ideals often prescribe what is right and wrong, such as in the
case of fundamentalism. If one person violates a law, perhaps everyone would -

In Stage 5 (social contract driven), individuals are viewed as holding different opinions and values. Similarly, laws are regarded as ‘social contracts’ rather than rigid dictums. Those which do not promote the general welfare should be changed when necessary to meet "the greatest good for the greatest number of people". This is achieved through majority decision, and inevitable compromise. Thus, democratic government is ostensibly based on Stage 5 reasoning.
In Stage 6 (universal ethical principles driven), moral reasoning is based on abstract reasoning using universal ethical principles. Laws are valid only insofar as they are grounded in justice, and a commitment to justice carries with it an obligation to disobey unjust laws. Rights are unnecessary, as social contracts are not essential for deontic moral action. Decisions are not reached hypothetically in a conditional way but rather categorically in an absolute way, as in the philosophy of Immanuel Kant. This involves an individual imagining what they would do in another's shoes, if they believed what that other person imagines to be true. The resulting consensus is the action taken. In this way action is never a means but always an end in itself; the individual acts because it is right, and not because it is instrumental, expected, legal, or previously agreed upon. Although Kohlberg insisted that Stage 6 exists, he found it difficult to identify a sufficient mass of individuals who consistently operated at that level for him to claim statistical significance in all his studies.

At age 10 the boys displayed mainly Stage 2 but there were examples of Stages 1 and 3. By the age of 22 no one used Stage 1 reasoning and Stages 3 and 4 were predominant. By the age of 36 and the end of the study, there was only marginal evidence of Stage 5 reasoning (around 5%).
In 1976 James P Shaver & William Strong raised the question of whether most people develop beyond Stage 4.
If, as in Integrated SocioPsychology, Kohlberg’s stages are seen as the outputs of
