I’m a bit hazy on the details, but broadly, two agents with common priors but different evidence (ie. different life experiences or expertise) can share their knowledge and mutually update based on their different knowledge, eventually converging on an agreed probability distribution.
But whether I believe in the info you give depends on my belief in your credibility, and vice versa. So it’s entirely possible to exchange information and still end up with different posteriors.
