I mean everyone shits on Kahnemann and co. about many results not replicating, but is there a similar effort to test and replicate RPDM etc.? One frustration I have with that field (but maybe just haven't read enough) is that the answer to "how to make better decisions"...

A lot of RPDM seems to me (again, may need to read more) very descriptive of what experts do, then gives you CTA to become more of an expert. But there's little mechanistic explanation that generalizes outside of "be expert in field"

Your understanding is correct! And I think your frustration is reflective of Shanteau and Weiss's frustration in the paper. To be fair to them (and to you) they (and you!) seem to want an objective function with which to compare decision quality. And that's fair!

But it's an open question if that's possible in real world decision making scenarios. NDM's approach doesn't get at this at all, and instead goes 'ok, we want to help people make better decisions in messy real world environments, how do we do that?'

One interpretation of their paper is "maybe we cannot come up with an objective decision function for real world decision making scenarios and the best we have is NDM-like tools." But, noooo, they don't conclude that. They instead say "NDM is also useless for this purpose."

Which — sure. They're entitled to their own opinion. But when the military started funding NDM, they did so because they were tired of funding classical JDM research that produced decision tools that nobody used. Maybe that should tell them something? I don't know, man.

Maybe my frustration comes from having read Heuer's "Psychology of Intelligence Analysis" as one of the first treatments of decision making I looked into. Same context as NDM (military), but very different approach.

Oh so this is actually really interesting! I actually *do* think JDM research is very useful in intelligence analysis, geopolitical forecasting (e.g. Tetlock's work) and also in finance. These are wicked domains, and these tools do much better there!
