AAT is very specific. Independent invention is evidence for the attractiveness of an idea (and thus, one hopes, its truthfulness) but it's unrelated to AAT.

People with severe medical problems need huge amount of resources merely to satisfy their preferences of "not being dead" and "not being sick."

Sure. But you're telling me that two healthy individuals are equally efficient at converting resources into happiness? What evidence is there that the Brahmin is not ten times as capable of happiness as the Untouchable?

AAT is very specific: if you are absolutely certain that someone else is rational, then your posteriors and their posteriors must be equal.

You need to have common knowledge of each other's estimates, common knowledge of each other's rationality, and common priors.

I thought you didn't need common priors, and I was wrong. Editing. (I might have had in mind Hanson's result that if you agree on the method to generate priors, then that's enough.)
