If someone can correctly explain a position but continue to disagree with it, that position is less likely to be correct. And if ability to correctly explain a position leads almost automatically to agreement with it, that position is more likely to be correct. (See free trade). It’s not a perfect criterion, of course, especially for highly idiosyncratic views. But the ability to pass ideological Turing tests - to state opposing views as clearly and persuasively as their proponents - is a genuine symptom of objectivity and wisdom.
