Indeed. Since message boxes and confirmations are used so frequently and often unnecessary users have trained themselves to just click on the far left or far right button to get rid of it. They don't read it, they don't want to understand what happened, it just interrrupted their flow and they want it to be gone. Pushing decisions to the user in form of confirmations won't ever really work probably due to a Pavlovian urge to close such things as fast as possible.
