Spaced repetition is a memory strategy that utilizes the scientifically supported concept that distributing study sessions is superior to cramming. By using an application, individuals can customize their own spaced repetition timetable, effectively establishing dependable memories for any subject they select. This approach shifts memory from being a random occurrence to a conscious decision.
Michael Nielsen, a well-known proponent of spaced repetition, has provided valuable insights into its implementation. In a Twitter discussion, Nielsen elaborates on his methodology: choosing the appropriate information for his review mechanism, deciphering the ideal content size for each element, and recognizing that memory by itself does not ensure comprehensive understanding of intricate processes.
Nielsen underscores the systematic aspect of memory with spaced repetition:
The most significant change is that memory is no longer a random occurrence, subject to luck. Instead, I can be confident that I will remember something, with minimal effort: it turns memory into a choice.
Nielsen employs Anki, an open-source tool featuring both desktop and mobile platforms that synchronize effortlessly. This capability is especially beneficial for incorporating learning into everyday activities, such as reviewing on a mobile device while waiting in line.
Anki assists in tackling cognitive biases, like the inclination to forget uncomfortable truths. Charles Darwin noted this in his autobiography, highlighting the necessity of recording contradictory information promptly to mitigate this bias. A spaced repetition framework can support the retention of such essential facts, potentially fostering more resilient thinking.

Anki-powered spaced repetition also integrates retrieval practice and interleaving, further boosting learning effectiveness.
