Very intriguing concepts. I'm thinking of this more from the science
information
point of view, and of course we have to have systems for the manipulation
and evaluation of speculative data in science. In my decision on where to
go, I have to evaluate things like what kind of system would be superior for
generating and evaluating ideas - will I do better at a smaller school where
everybody knows each other or at a larger school where individuals are more
isolated? It's a pity we have little real data on this kind of thing and that
my decision will consequently be ill-informed on this matter.
To rephrase my ideas, the engineering *does* get done on these systems in
the sense that we do create speculative markets and other information
evaluation
systems, but the decisions tend to be ill-informed since the empirical data
is scanty. So it seems like your idea should be an easy go. I'm surprised
UCB wasn't interested but I wasn't there.
Biologists often address the issue of how to test unmodelable systems by
making extreme simplifying assumptions. Often, these work even when
the assumptions are seriously bogus. An example would be quantitative
genetics. Quantitative genetics basically assumes that a) each gene
has a small effect on the outcome and b) effects of different genes can
be added without considering complex interaction. Both these assumptions
have recently come up very wrong. Nonetheless, quantitative genetics
has been spectacularly successful in breeding and in gene mapping.
In addition, testing a theory, even one you know is wrong, can provide "cover"
for developing techniques.
