I was particularly interested in subjective Bayes theory due to the way it seems to interleave human input with mathematical theory.
I first learned about it from a non-fiction book in which these techniques were used by scientists in the US to locate Russian ICBMs that were test-fired during the Cold War and landed in the ocean. The wisdom of experts was quantified and fed into a simple Bayesian subjective probability calculation which lead to prioritization of target areas to investigate and the US located on either the first or second try - I can't recall. I've seen a few other interesting applications of this as well.
I'm not an expert in this area, but you sound like you might be - so I thought I'd take the change to ask :)
