Double blind is great in science where a finite and known set of variables are being tested.
Real life policy-making does not have the benefit of involving a finite and known set of variables.
Generally speaking, I think it’s important to understand the distinction between a logical calculation of a finite (hence calculable) system, versus the phenomenological reality of navigation in the world, which by its nature always involves more information than one can be capable of articulating.
Sorry if that sounds eggheadish. I don’t know how to say it otherwise without expanding it into a huge wall of text.
Beyond the known and articulated, there is the known and unarticulated. For example “How to make cookies” can be conveyed in finite words (a recipe), but “How to catch a baseball” can be conveyed only through practice.
Systems such as you’re describing are good for handling articulated competency, such as the cookie recipe. But I fear that “making good decisions about what to do” isn’t something that can be conveyed merely in words.
This seems to me to be related to the idea of a “double blind” scenario, in that in order to “blind” the parties one needs to know what information is valid to consider and what information isn’t.
