Huh. I don't think it's neccessary to say that you could be wrong. I think that the ability to be wrong is fundemental to being human. Even a Saint can be wrong -- even if you ask the Catholic church. In fact, it is abilty to be wrong that defines the soul, according to many religious philosiphers.
Anybody can be wrong. And I think, realisticly, very few answers to most questions contain tested code.
