An anonymous reader writes "Over a third of undergraduate students admitted to some form of cheating at one of America's top research universities, according to a survey published November in the journal Science and Engineering Ethics (abstract). The researchers expected to find more cheating among the top-performing group — and at the minimum at least some students with excellent grades cheated. Not so. As it turned out, the overall cheating rate was similar to that found in other studies, but the types of cheating and stated reasons for cheating were all over the map. Researchers uncovered one trend among the cheaters: the perception that teaching assistants either ignored or didn't care about cheating."
