I have taught at multiple honor-code institutions (and still do). It does not prevent cheating. However, it shifts focus: I can go about my teaching life starting from an assumption that students are not cheaters—and I'm personally convinced that most aren't.

The flipside is that when you do catch a cheating case, you completely throw the book at them. It's legitimately easier to cheat under an honor system, if that's what you're wanting to do... so my assumption is that if we catch you at it, it's likely part of a pattern, and if we catch you multiple times the pattern is irreformable. It is not uncommon at honor-code institutions to expel students on the second offence (sometimes even on the first).

I do think that cheating is less prevalent at my institution (and my previous institution) than it is in the larger university population.
