Spaced repetition is progressive overload for your brain.

Justin Math's blog post argues that forgetting is part of learning, and spaced repetition works like progressive overload in weight training: waiting until a memory is fuzzy creates resistance, and the effort of retrieval strengthens memory. The post, which is an AI-assisted teaser for longer manually written articles, emphasizes that the goal is not easy review but building strength so that previously hard material becomes easy.

If you review something immediately, your brain doesn’t have to work very hard. But if you wait until the memory is fuzzy… Now you have resistance. You’re pulling information out of long-term memory. That effort is the rep. Spaced repetition is basically progressive overload for your brain. The goal isn’t to make review easy. The goal is to make yourself strong enough that what used to be hard becomes easy. The wait creates the weight. Here are the 100% manually-written long-forms that this teaser is distilled from, if you want to dive deeper: Spaced repetition is more than memorization – it’s also generalization. https://justinmath.com/spaced-repetition-is-more-than-memorization-its-also-generalization/ Cognitive Science of Learning: Spaced Repetition Distributed Practice https://justinmath.com/cognitive-science-of-learning-spaced-repetition/ Spaced repetition is so similar to weight training that it might as well be called “wait” training. https://justinmath.com/spaced-repetition-might-as-well-be-called-wait-training/ Want to get notified about new posts?
