The studies quoted here are in the mid 80s and early 90s before the rise of better and easier UI methods or more powerful search. I'd have to call this conclusion into question.

There's also a big difference in what people know, what people prefer, and what knowledgeable people can do most quickly.

Cross reference this with Dan Russell's research at Google that indicates that very few people know how to use ctrl-f to find or search for things in documents. - https://hyp.is/7a532uxjEeyYfTOctQHvTw/www.youtube.com/channel/UCh6KFtW4a4Ozr81GI1cxaBQ

Relate it to the idea of associative (memory) trails (Memex), songlines, and method of loci in remembering where things are -- our brains are designed to navigate using memory

The Aboriginal flag was developed in 1971 by Luritja artist Harold Thomas. Centering its importance to Aboriginal Australians, the sun appears in the middle of the flag.

It's subtle here, as in other instances, but notice that Hamacher gives the citation to the Indigenous artist that developed the flag and simultaneously underlines the source of visual information that is associated with the flag and the sun. It's not just the knowledge of the two things which are associated to each other, but they're also both associated with a person who is that source of knowledge.

Is this three-way association common in all Indigenous cultures? While names may be tricky for some, the visual image of a particular person's face, body, and presence is usually very memorable and thereby easy to attach to various forms of knowledge.

Does the person/source of knowledge form or act like an 'oral folder' for Indigenous knowledge?
