Business students most likely to cheat.
Teaching Christian Ethics is fun. Teaching Christian Ethics is about taking a bunch of people who already follow the rules and challenging them to get really radical. Challenging them to get beyond just following the rules.
Sure, there's some cheating--they don't all already follow the rules, and the stress certainly does get to some of them. But the basic presumption among people who take Christian Ethics is that something like "following the rules" is a good thing.
What on earth do you teach people who don't even follow the rules they already know about? Who think that "following the rules" is something idiots, wimps, children, or prudes do? Who pride themselves on their own cleverness in cheating successfully?
How do you even talk to them?
