In brief: Short summaries of important ideas are far more "mind-ready" than longer and more detailed academic texts on the same subjects. I originally proposed Domains for other reasons, but I find that they are handy enough that they seem the perfect example of making complete systems of thought fit on one page, and merely expanding each point as a separate domain. I further argue that these more elaborate formal presentations merely give the illusion of greater precision and accuracy, when in fact these overwhelming details add little value to the material. Lastly, many formal presentations of concepts are made to seem complete in themselves, with no further challenging questions to be asked, merely elaborations on the main theme presented. Certain domains allow us to "unpackage" such a presentation, unravel it, and ask if we can't formulate it as a domain itself. Then all the loose ends become much easier to identify and pursue.
