Thanks, interesting!
I've been thinking about writing an article on risk assessment as a worthwhile field of study or source of tools for LWers. The upshot is that it offers a pretty good rationality toolbox and there are lots of jobs, but it's suboptimal in some important ways.
I took a course on health risk assessment and it came pretty close to being Rationality 101 - covered the gamut from probability theory to expected utility to cognitive biases.
ETA: Googling something else returned this, which I hadn't read but is presents an excellent example of the kind of thing I mean by "suboptimal".
A very clear-minded introduction to map-vs-territory ideas in the context of risk analysis. Nothing particularly new here, though the specific examples he gives may be of interest to LW readers.
