### One of the outcomes of a Bayesian discussion about a car that two
observers saw briefly, and remember differently would be to reduce both
observers' levels of certainty. If John thinks he saw a Camaro and Jack
thinks he saw a Mustang, then they will agree that neither one knows what
they saw, but it could have been either model, with equal probability.
So there is no agreement to disagree, but a mutual widening of the range of
states believed to be compatible with the truth.
