MIT's Sloan School of Business won't be adding courses on ethics because there is no need to.
I kind of imagined the problem was that business ethics wasn't properly taught in business school. Dean Schmalensee's argument for the status quo (he gives no concrete examples of how teaching ethics will be integrated into the curriculum) just makes no sense.
You might not be able to teach ethics, but you can teach ethical behavior. That's why every law student takes a class on professional responsibility as a prerequisite to a diploma. I will also note that Sloan's two ethics classes are literature courses. None of the law classes appear to contain any material on ethics.
Integration is great, but shouldn't business students have a proper foundation in ethics before they are expected to pick out the tricky ethical areas in their other courses?
