I agree that having someone tell me I'm wrong is useful, but it seems to me that we couldn't possibly all be dependent on someone telling us before we know. What about the scientific method?

Reminds me of a famous video clip, "Feynman on the scientific method". "If it disagrees with experiment, it's wrong"

Good point. Maybe it isn't always a human that tells us. Something or someone informs us we are wrong. We just have to pay attention and keep an welcome the information.
