isn't that also related to active vs passive knowledge?
active knowledge i can produce on command. passive knowledge only comes up when it is triggered from the outside.
a lot of things we know are only accessible when they are triggered. i could not describe the path through a forest, but i know it when i walk it. same for the process to solve a particular problem. i could not describe the whole way. only if i follow the steps can i remember the next steps. and if there are multiple possible steps at some point, only for the choices that are actually triggered will i remember what comes after.
you can follow me and learn the steps by observing me, but you will only learn the steps that we actually do. and i couldn't possibly give you a list of all other potential steps.
in the latest video by tom scott, he watches people creating bells. the guy observing the molten metal knows when it has the right temperature by just looking at it. he learned that from years of practice, and his future replacement will learn it by observing him.
