      In everyday activity, you can almost always SEE or HEAR what to do next. The possibilities are inherent in the perceptual environment. Formal notation is a collection of tricks for making the same possible in abstract realms. It’s all our brains can do. https://meaningness.com/metablog/rational-pcr …pic.twitter.com/ZbCShOXASt

      Something I’ve been incoherently wondering about in recent years is the extent to which my peculiar cognitive style rests on a peculiar memory control unit. It seems to be much more content-addressable than most people’s, supporting some sort of fuzzy match.

      I’m not particularly good at memorizing facts, but there’s vast quantities of conceptual stuff in there from every field imaginable, and it constantly throws up more-or-less relevant things I read decades ago and hadn’t thought about since.

      Maybe the fuzziness of the match means that I effectively have access to much more stuff than someone else who’d read the same material but carefully indexed it. Which has both benefits and costs.

      I've worried a lot about this very particular point, for the obvious reason (I worry that memory systems may damage creativity). Can make a pretty case in both directions, without anything particularly dispositive.

      The most interesting pro-case was after using memory systems to really pull apart a particular proof (of the spectral theorem): http://cognitivemedium.com/srs-mathematics  Afterward, totally unexpectedly, I went on a long walk, and found many new and totally different proofs simply arising

      in waves as I walked. The effect faded, but on the rare occasions I think much about mathematics I will find ideas obviously somehow connected to that proof often arise in a delightfully generative fashion; the process encoded not just details...

      ... but also the fuzzy generative stuff in a particularly effective fashion. This isn't quite n=1 (I've done the same, not quite as successfully, a few other times), but it is small n.

      omg this is super cool! I suspect this hard-to-describe thing of “mental modes” or “states of cognitive awareness,” especially the non-ordinary states of cognitive awareness, is enormously important and almost entirely unstudied.

      Many of my projects require specific non-ordinary cognitive modes to proceed, and it usually takes me about three full-time days to get myself into the relevant state. Any significant interruption aborts the process.

          This is incredibly inefficient; I need five clear days to get two days of work done (three in cognitive-state prep) and how often can that be arranged?

          “Hacker trance” is the best-known example of this, although less extreme. You’ve finally managed to get the structure of a large codebase in your head and you are working out a refactoring and either (a) you work 48 hours nonstop to get it done or (b) your pointy-haired boss

          Yep. And the feeling of “whelp now that I just had those meetings there goes two days of non work. Now I look like im@doinf nothing to my peers.”

          I find the interruption cost can be reduced by making sure I do some chunk of work on interruption days. Even when the chunk is routine, it seems to signal to my mind that I should stay in some approximation to that state. Too often not possible, though.
