 In order to make the case for this claim, he had to show that children make characteristically moral judgments about some transgressions, and that their judgments about conventional transgressions were systematically different. To do that, Turiel needed an empirical test that would indicate whether a normative judgment made by an experimental participant—child or adult—was a moral judgment or a judgment about a conventional matter. In constructing his test, Turiel drew inspiration from the philosophical literature on the definition of morality. He focused on several of the necessary conditions for moral judgments that philosophers had proposed and used them to guide the construction of the test he needed.
