There are a lot of things that techie types esteem beyond their worth. Spaced repetition systems sound like unnecessary complication on top of flashcards, and thus an obvious example of that phenomenon. They are not.
I used spaced repetition to make a professor think I was Talented at learning German. I used spaced repetition to ace tests on persnickety details of the C programming language and POSIX minutiae. I used spaced repetition to make people think I was naturally good at things when I wasn’t, and I used spaced repetition to improve my fiddly fundamentals in things I actually was naturally good at.
I am not going to provide any motivating cognitive science, hand-wavey or otherwise, because that argument has been made and I don’t need to.
Broadly, my experience led me to believe that spaced repetition is the best way to be able to remember things that you don’t actually care about in your gut. The things you care about you can always recall–a phrase in a foreign language that made you laugh hard, your crush’s class schedule, the core idea of your master’s thesis…
However, there’s a lot you may want to have memorized that you can’t emotionally care about until you need it: CPR cadences, interview answers, the word in a foreign language for “can opener”… When the moment strikes, you will care, but until then, how do you make it stick?
In my university days, there was an email I sent around to everyone who asked about my setup, so I’m going to reconstruct that resource here.
what is it good for? (absolutely something)
- vocabulary - in one’s native or acquired tongue, and especially when you need to memorize fiddly grammatical metadata along with a denoted meaning
- memorizing poems/prayers/lyrics - you will need to split the poem up into little bits such that you are prompted with two lines and must recall the line that follows
- dates, names, formulae, anything fiddly that you can’t rely on a holistic understanding for
I have yet to find anything surpassing Anki.
why I am not sharing my deck
You really need to build your own. I know that seems like trite character-building nonsense, but the cards you make yourself are a thousand times more useful than decks you can import2. I advise being liberal about adding cards to your deck, but also very open to deleting them – it’s easy to realize that something is only worth memorizing with a certain cue, and quick to get rid of something you realize you didn’t care about at all.
