Spaced repetition systems can be used to program attention

Spaced repetition memory systems make memory a choice, but the computerized component’s value lies specifically in dynamically scheduling and selecting questions to be reviewed. In some sense, the efficacy of a Spaced repetition memory system comes from its power to program your attention (Programmable attention). Think: “{cron} for your mind.”

Manually making decisions about which cards to review would be far too taxing on a per-card basis. The transaction cost is too high. When that work is mostly outsourced, you can make a coarser decision—to devote your attention to SRS practice for 10 minutes—and then let your attention be directed by the machine within that block.

Within a traditional flashcard-style system, you can use this observation to go far beyond memorization: see Spaced repetition memory systems can be used to prompt application, synthesis, and creation and Spaced repetition may be a helpful tool to develop or change habits.

But the core concept—automatically arranging and presenting tasks according to some expanding schedule—can be instantiated in many interfaces and domains. I call this notion Spaced everything.

Evergreen note maintenance approximates spaced repetition

Triage strategies for maintaining inboxes (e.g. Inbox Zero) are often too brittle, vs. using spaced-repetition to “approximate” inbox grooming.

I use this concept to engage with my implementation of A reading inbox to capture possibly-useful references
