Hauser uses artificial moral dilemmas as a research strategy. The reason is that people already have moral judgments of real world cases such as abortion and euthanasia, so there is no intuition left. In artificial moral dilemmas intuition plays an important role. A second advantage of artificial cases is that they can be subtly modified to observe the effects on moral judgments of people. There is an internet version of the test called the Moral Sense Test which is aimed at a worldwide public.
