Why Does College Promote Development in Moral Judgement?

Evidence is reviewed showing that college attendance is associated with development in moral judgement. Six interpretations of why college has this effect are discussed: (1) simple age/maturation; (2) socialization; (3) learning specific knowledge or skill; (4) generalized understanding; (5) intellectual stimulation; (6) self‐selection. Findings from longitudinal, experimental, correlational, educational and life experience studies are used to evaluate the plausibility of each interpretation. The last three interpretations are favoured over the first three.
