Very Short Notes on Honest Disagreement.

By Hanson and Cowen. I failed to record who linked it to me.

It seems to me that it is far from being verified that coming to agreement is as easy as Aumann 76 and the follow up studies indicated. Did they really include everything that is relevant to coming to agreement? How do you know?

By contrast, reversing this single assumption, assuming agreement is a lot harder than we realize, handily fits most of the data.

Well thought.

I'd play "disagreement is easy" by means of the inductive nature of knowledge... On the other hand, the result that someone else's inductive process gives different results should still move you substantially off a high-certainty position.

I'd expand that by comparing the bandwidth of the eye to the bandwidth of the voice.

The picture/1000 words thing already said it, though.

Though instead of 1000 words, I want a real estimate. Passing along the relevant features of a single tableau would take, what, say half a day?
