If two people disagree, is at least one person wrong?
But in general, can we say that at least one of them must be wrong?
It's difficult to make a blanket statement like that since it depends on the situation. In some cases, both parties might be partially correct or incorrect, or they might be equally informed and their disagreement could simply come down to a difference in opinion rather than a factual error. It really varies from case to case.
