Effective learning: Rules of formulating knowledge (1999)

I had tons of material in SuperMemo for years. Gave up and fully switched to Anki.
At least I'm thankful for his spaced-repetition algorithms. Also, his articles restored my love for learning and helped me confirm that school was an insane waste of time and resources.
SuperMemo is actually almost the only reason I still keep a Windows VM.
Anki way makes more sense.
There's a reason Anki is used so heavily by med students these days.

It’s a bit of a treasure trove for us spaced repetition nerds!
You can fully understand something without being able to recall it perfectly later.
Learning is circular. You do it step by step, one bite at a time: you learn a fact, you understand its connection to other facts you know, you gain a little knowledge, you repeat.
I think their mental metaphor is that cards allow you to memorize nodes, and understanding is having a feel for the entire graph. But cards also help you to memorize links between nodes, subgraphs, overviews, principles, etc...
I also think it's mostly a ready made array of excuses to read off to somebody who is having a crisis of faith about whether a Anki is helping them or not: you're holding it wrong. You haven't put in the work. Are you making your own decks, you can't use other people decks because making your own decks = understanding (for mysterious reasons, do you really understand something you can't remember?) Are your facts atomic enough? Basically direct or indirect paraphrases of the Supermemo wiki.
Supermemo didn't discover anything, he computerized something that desperately needed to be computerized, and at that point wasn't restricted to the algorithms that could be executed by shuffling around physical cards, such as Leitner boxes (which are awesome, still, by the way.) His analysis is great to read and often insightful, but is no more profound than many others and often far less scientifically grounded. People just are addicted to parasocial relationships with self-improvement gurus.
I got through uni on entirely point 1, and only relied on accidental memorization from the process of understanding.
I find alot of study advice under-emphasise point 1, and over-emphasise memorization techniques.
