>An intervention aimed to discourage participants from choosing the cheating-enabling environment based on social norm information did not have the expected effect; on the contrary, it backfired. In summary, the results suggest that people low in moral character are likely to eventually dominate cheating-enabling environments, where they then cheat extensively.
In other words: we tried to tell the cheaters "you wanna cheat? fine, you can only play with the other cheating pieces of crap." The intent was for this to be a punishment, but it turns out they like it. The strategy backfired.
Don't dismiss this as a "well duh" thing, there's cool stuff in here!
