I’m not understanding your disagreement. Of course popularity is just a prior. The less popular a given position, the stronger your prior should be against the other person holding it. Doing that will lead you to be less wrong about what the other person means by what they’re saying.
What is the difference between what you said and “your prior for whether someone believes an unpopular position should be lower the less popular the position is, and you should update your prior based on how clear their statement was”?
