I just thought this was interesting and so will pass it along. In my Internet law course this morning, we were talking about downloading songs, movies, etc. The students, to a person, stopped downloading when they started law school because the consequences to them went up -- the risk of getting caught was still low in their view, but the practical consequences to the bar examination process made the costs outweigh the benefit. They had made the same conclusions about speeding, driving after drinking, and other topics.
Interestingly, when I asked whether it was because of a greater sense of morality or professionalism instilled into them by law school, they did not think so, attributing it instead to becoming more conservative (i.e., risk averse).
Anyhow, I thought it was an interesting discussion worth passing along for that reason alone.
