If you're into educational theory, you might like Alfie Kohn's book No Contest: The Case Against Competition. It's a really good look at the systemic effects of competition. It touches on cheating among other things.

It's funny, these days I find myself mostly reading counter-intuitive stuff. I figure if it's intuitive, I'm probably smart enough to have figured it out already. This book (and his other book, Punished by Rewards) is a really good example of something that just diffs with your current knowledge.
