Spaced repetition can lower the stakes around destructive inbox-maintenance operations

Inboxes only work if you trust how they’re drained, but Triage strategies for maintaining inboxes (e.g. Inbox Zero) are often too brittle. In large part that’s because Software interfaces often harmfully frame destructive operations as final decisions, not contingent preferences.

If you recast the destructive operations as “not right now,” they feel completely different. That browser tab isn’t gone—it’ll come back later. Maybe it’s a day later at first, then if I skip it again, a few days later, then maybe a week, and so on, until “not right now” is effectively “close”… but it doesn’t feel nearly so stressful. This notion can be applied to task queues, reading lists (A reading inbox to capture possibly-useful references), email inboxes, etc. Spaced repetition mechanics create a sense of effortlessness.

This is an example of a way in which Spaced repetition systems can be used to program attention.
