They’re worth looking for because they are so valuable: a shovel is much more effective than your hand, but a power shovel is orders of magnitude better than both - even if it requires training and expertise to use. We use any number of such neuroprosthetics 2, but there are always more to be discovered.

Even if we do not remember exactly, merely remembering a reference can be just as good, like the point of reading a manual or textbook all the way through: it is not to remember everything that is in it for later but to later remember that something is in it (and skimming them, you learn the right words to search for when you actually need to know more about a particular topic). They make the best calendars, because they always check what there is to do today. They remember terabytes because we’d forget. They do arithmetic perfectly because we can’t 1.

One of the most fruitful areas of computing is making up for human frailties. I review what this technique is useful for, some of the large research literature on it and the testing effect (up to ~2013, primarily), the available software tools and use patterns, and miscellaneous ideas & observations on it. Because of the greater efficiency of its slow but steady approach, spaced repetition can scale to memorizing hundreds of thousands of items (while crammed items are almost immediately forgotten) and is especially useful for foreign languages & medical studies. Spaced repetition is a centuries-old psychological technique for efficient memorization & practice of skills where instead of attempting to memorize by ‘cramming’, memorization can be done far more efficiently by instead spacing out each review, with increasing durations as one learns the item, with the scheduling done by software.
