Lawrence Kohlberg's work created a foundation for moral decision making and development. He demonstrated his ideals by using the "Heinz Dilemma" in which he created. The basic premise of the dilemma is that Heinz is the husband of a woman who is dying of a kind of treatable cancer that. There is a drug that can possibly cure his wife's cancer, but the problem is that Heinz can not raise enough money to pay for the extremely expensive cure. The questions is about whether Heinz should steal the drug because he can not raise enough money, or whether he should just let his wife die.
Kohlberg focused on the reasoning behind making a decision as difficult as this. His work was later criticized by many. I found the criticism of the fact that Kohlberg's work has a significantly low correlation with real world applications to be the most interesting and pressing. Correlational studies have shown a score of around 0.3, which basically points out the fact that although Kohlberg's work influenced how people approach moral decision making, it really only works with hypothetical problems, rather than issues we would have to deal with on a daily basis.
