One of the "handy wavy preconditions" is that they share priors. This nearly never happens in the real world. Almost all disagreements can be traced to differing priors.

No - the precondition is that agents share common knowledge of each others' priors (not that they have the same priors).

Here's the paper I read: http://www.ma.huji.ac.il/~raumann/pdf/Agreeing%20to%20Disagr...

Here's how it starts: "Theorem: if two people have the same priors..."

Whoops, seems you are correct. I'd misunderstood this, my apologies.
