Hmm, I just skimmed something about Carter-Zimmerman [a polis] and some
characters named Paolo and Elena...If the book is good, I'd rather avoid
everything, even character relationships. (there's also a whole thread in
the sl4 archive waiting for me when I finish the book).

Actually this precisely answers my question. There is no need to model
human emotions (or emotional responses: panic, urgency, fondness, self
loathing). Using Bayes theorem for a quick and dirty heuristic solution
gets around the Framing Problem(*) assuming the AI has seen similar
(Well, there might be a need to model emotions in order to *understand*
humans better, but there is probably no need to *use* that model for
actual problem solving),
(*) The Framing Problem: Correct me if I get this wrong, I'm not that
much of an AI buff, but I think the problem can be illustrated by an
automaton trying to diffuse a bomb before it goes off. The problem is
there are so many solutions to choose from, how does ve pick the right
one in the alloted amount of time without thinking through and weighing
all the solutions first...or that's a description of the Framing Problem
that I read once.
On Human Emotions:
(Warning: spoliers bout Steven Pinker's "How the Mind Works" and Matt
Ridley's "The Origins of Virtue" follow)
I found that Steven Pinker's "How the Mind Works" did a great job of
explaining human emotions in the context the computation model of mind.
The Origins of Virtue touched upon the emergence of emotions as a way out
of the Kidnapper's Dilemma(**). Pinker goes further and explains why people
genuinely feel generosity, love and compassion (basically, generous
strategies evolve, and then cheaters, then cheater-detecters to "out"
the cheaters, then strong, *genuinely* generous feelings emerge from the
selection pressure to get past the cheater-detectors - or something like
that, it's been a couple years since I've read the book).
Pinker also describes why emotions can drive people to go berzerk and all
sorts of fascinating examples of food taboos. If you thought OoV was too
short, pick up HTMW. Great book, also (though not a replacement). I think
Pinker wrote the book right after spending a year with Cosmides and Tooby.
I've also read "Descarte's Error" by Antonio Damasio. It was good, but not
great like OoV and HTMW, were.
(**) The Kidnapper's Dilamma: You've kidnapped someone, but you've
changed your mind. You can release your captive on the condition that
she won't tell anyone. The dilemma is really your captive's because
there is no way to prove to you that once she's free, she won't tell
the police. One way out is to confess an equal crime so that neither
of you has incentive to defect (ie. snitch). Since it's probably
unlikely that the victim has any such skeleton in her closet (or it's
hard to convince the kidnapper), the kidnapper has no choice but to
kill her. Emotions are a way of persuading the kindapper, when in
fact there is no logical reason to let the victim go (see The Origins
of Virtue for a less-mangled description).
