My experience is not that it's a matter of being busy, or even lazy. These people have simply convinced themselves that working with computers is hard. They got lost because they assume they'll get lost. They stop at an error message not because it takes two minutes, but because they assume dealing with the task is insurmountable. It's almost like testing anxiety--they think they're going to fail, so they fail, and it entrenches a response of frustration for no rational reason.
