9/8g The card index technique is based on the experience that one cannot think without writing – at least not in demanding, selectively accessing memory-based contexts.

This also means that one cannot think without making allowances for differences.

I like this slightly more differentiated instantiation for thinking better than Ahren's assertion that one can't think without writing. Luhmann qualifies it over and above Ahrens who elides meaning if this was the source he may have been tangentially referencing. (Was it an explicit reference? check...)

Quotations are easier to collect than writing things out in one's own words, not only because it requires no work, but we may be afraid of changing the original meaning by changing the original words or by collapsing the context and divorcing the words from their original environment.

Perhaps some may be afraid that the words sound "right" and they have a sense of understanding of them, but they don't quite have a full grasp of the situation. Of course this may be remedied by the reader or listener not only by putting heard stories into their own words and providing additional concrete illustrative examples of the concepts. These exercises are meant to ensure that one has properly heard/read and understood a concept. Psychologists call this paraphrasing or repetition the "echo effect" (others might say parroting or mirroring) and have found that it can help to build understanding, connection, and likeability between people. Great leaders who do this will be sure to make sure that credit for the original ideas goes to the originator and not to themselves simply because they repeated it, especially in group settings where their words may have more primacy amidst their underlings.

(I can't find it at the moment, but there's a name/tag for this in my notes? looping?)

Beyond this, can one place the idea into a more clear language than the original? Add some poetry perhaps? Make the concept into a concrete meme to make it more memorable?

Journalists like to quote because it gives primacy of voice to the speaker and provides the reader with the sense that they're getting the original from which they might make up their own minds. It also provides a veneer of vérité to their reportage.

Link this back to Terrence's comedy: https://hypothes.is/a/xe15ZKPGEe6NJkeL77Ji4Q

Kaiser says that "description and illustration are complementary, they give together a more complete picture than either without the other" and this sentiment is similar to Mortimer J. Adler and Charles Van Doren's pedagogy of restatement and providing concrete examples a means of testing understanding.

See: - https://hypothes.is/a/RgUa-mOcEe6PChv_seYXZA - https://hypothes.is/a/B3sDhlm5Ee6wF0fRYO0OQg

Adler/Van Doren use the statement of unity of a work as an example of testing one's understanding of a work and its contents.

(Again, did this exist in the 1940 edition?)

Who do McDaniel and Donnelly 1996 cite in their work as predecessors of their idea as certainly it existed?

Examples in the literature of this same idea/method after this: - https://hypothes.is/a/TclhyMfqEeyTkQdZl43ZyA (Feynman Technique in ZK; relationship to Ahrens) - explain it to me like I'm a 5th grader - https://hypothes.is/a/BKhfvuIyEeyZj_v7eMiYcg ("People talk" in Algebra Project) - https://hypothes.is/a/m0KQSDlZEeyYFLulG9z0vw (Intellectual Life version) - https://hypothes.is/a/OyAAflm5Ee6GStMjUMCKbw (earlier version of statement in this same work) - https://hypothes.is/a/iV5MwjivEe23zyebtBagfw (Ahrens' version of elaboration citing McDaniel and Donnelly 1996, this uses both restatement and application to a situation as a means of testing understanding) - https://hypothes.is/a/B3sDhlm5Ee6wF0fRYO0OQg (Adler's version for testing understanding from his video) - https://hypothes.is/a/rh1M5vdEEeut4pOOF7OYNA (Manfred Kuenh and Luhmann's reformulating writing)

Field Notes, a manufacturer of notebooks, uses the credo "I'm not writing it down to remember it later, I'm writing it down to remember it now." This is an fun restatement of the idea behind the power of the Feynman technique.

Link to Ahrens' version of this idea.

Sönke Ahrens outlines this broad idea of how one practices the Feynman technique for understanding using one's notes in How to Take Smart Notes, but he doesn't use the name Feynman technique. Certainly the idea of writing things down to test one's understanding predated Feynman, does anyone know of historical examples of this pattern/technique prior to Feynman? Does it have other names in the literature?
