## the research
-roediger and karpicke's 2006 research is the landmark study. they had students either re-read a passage or take a test on it (with no feedback). short-term, the re-readers did better — they'd just seen the material. but after 2 days and 1 week, the tested group dramatically outperformed the re-readers.

-the effect size is big: retrieval practice boosts long-term retention by 50-80% compared to re-reading. this has been replicated across hundreds of studies, different age groups, different subject matters.
+roediger and karpicke (2006) showed that students who tested themselves retained 50-80% more than students who re-read, even without feedback — an effect replicated across hundreds of studies.

pulling information from memory — even unsuccessfully — strengthens the memory trace in a way that re-exposure doesn't. the effort of trying to recall is the learning signal. failed retrieval attempts are almost as valuable as successful ones, because the effort itself builds the neural pathway.
-this is why the best learning feels hard. see [[deliberate-practice]] — if it's easy, you're not learning. the discomfort of "i can't quite remember..." is actually the feeling of getting smarter.
