I couldn't have put it better myself! Having an open mind is all about what the Scientific Method entails, that is going where our observations lead us and having an open mind about when we are wrong, "No matter how beautiful the theory, if it doesn't match the observation, It's WRONG" (Feynman). The problem with a lot of belief and pseudoscience is that it's a guess where the observation does not match, however since it's "Beautiful" the creator of the theory is unwilling to let it go even though it is Wrong.
