Yes, I'll give it another try.

Yes. But it's difficult to conceive how it could have
turned out differently.

All right. So no Bayesians per se exist, but it's an ideal
that one speaks about, such as "rational". No exactly rational
people exist either. But for rational, we are able to reasonably
assert that, for example, one nation's population is more rational
than another nations (on perhaps a particular restriction).
But I don't get the parallel for "Bayesian". I use Bayes theorem
a lot in solving probability problems, have solved all the ones
I've seen on this list both intuitively (mathematically), and
formally (mathematically). I have always preferred the point
of view that readily accepts or postulates, or even agitates
for prior distributions, and goes right ahead with probability
calculus. So who is more Bayesian than I am?
What is the utility that you and the researchers find in referring
to a class of such agents by that description? (Eliezer once wrote
"[Vorlon voice:] We are all Bayesians now.")
A semantic analysis by context appears to show that it is being
used as a substitute for "clear-thinking", or "rational", or some
blend of such familiar concepts. It frankly sounds silly to me,
but (a) I did miss out on a lot of earlier Extropian and other
list discussions about this (b) if enough people I trust really
say the Emperor has clothes, then it's probably so, but *I* still
can't see them.
