Author here. Quite the contrary, actually — I’ve read all the above sources. On top of that, with the exception of Chambliss (which is a landmark work, to be clear), and Dreyfus (which I prefer to look at adaptations of; Accelerated Expertise has several updated or derivative scales that expertise researchers in the military use), I’ve talked to collaborators of these researchers, and in the case of Klein, am actively in contact with and am following the rest of the work of his community (https://naturalisticdecisionmaking.org/).

I’ve updated the bottom of the post to link to the many other articles I’ve written on expertise. These are either summaries of papers, or summaries of branches of the research, or pointing out obvious holes in the popsci representations of the research, or synthesise various (mostly military-funded) approaches to accelerating expertise.

This particular essay is a note from personal application.
