How Learning Actually Works According to Science
Re-reading and highlighting feel productive but are weak learning methods. Retrieval practice, spacing, and interleaving create durable understanding.
Why Repetition Alone Does Not Create Knowledge
Repetition alone doesn't create knowledge because it's passive. Re-reading builds familiarity, not understanding. Knowledge requires active retrieval.
