<p>Here’s my experience, FWIW. A quarter-century ago in grad school, I was proctoring an intoductory sociology final for my faculty adviser. I saw a girl who kept putting her head down on her desk and I remember thinking “She does the same thing I do when she’s trying to think.” Then I noticed there was a folded-up paper with writing on it beneath the under-desk bookrack. I picked it up and it was full of intro sociology info. I immediately took her test. We went out in the hall and I told her I had reason to believe she was cheating (I was very careful not to actually accuse her of it.) I told her she was not getting the test back and she would have to speak with the professor the next day. She did and said her dad was threatening to sue the school, etc. He ended up giving her a totally different test in his office. I was kind of ticked off because everyone told me I did the right thing, but she suffered no consequences. I did learn that it still pays to do the right thing, if only so you can live with yourself. I can only hope she learned something from the experience, but I doubt it.</p>
