This study shows the link between teaching ethics in a college setting and the evolution of student thinking about ethical dilemmas. At the beginning of the semester, students have a rigid "black and white" conception of ethics. By the end of the semester, they are thinking more flexibly about the responsibilities of leaders in corporate ethical dilemmas, and they are able to appreciate complex situations that influence ethical behavior. The study shows that education in ethics produces more "enlightened" consumers of (...) ethics information who are able to make sound determinations about responsibility in ethical dilemmas. (shrink)
