Full-text search is the ability to search every word in every document in a collection — not just titles or tags — returning results ranked by relevance to the query. It's the difference between a filing cabinet and a search engine.
The generation effect is the finding that information you produce yourself — by generating an answer rather than reading it — is remembered far better than information you passively receive.
Information architecture is the practice of organizing, structuring, and labeling content so people can find what they need. It determines the categories, navigation, and hierarchy of any information system — from websites to note collections.
An information diet is a deliberate, curated approach to what information you consume — choosing your inputs as carefully as your food inputs to protect cognitive capacity and focus on signal over noise.
Interleaving is a learning strategy where you mix different subjects or problem types within a single study session — instead of completing one topic before starting the next. It feels harder but produces better long-term retention and transfer.
Metadata is data that describes other data — the title, author, date, tags, and context attached to a file or document that make it findable, sortable, and understandable without opening it.
Tacit knowledge is expertise held in people's heads — hard to articulate, learned through experience. Explicit knowledge is documented, shareable, and searchable. The distinction is the foundation of knowledge management.
Taxonomy is a controlled, hierarchical classification system designed by experts. Folksonomy is a user-generated tagging system that emerges from collective use. Both organize information — they trade off control for flexibility and scalability.
The collector's fallacy is the mistake of believing that gathering information is the same as learning it — saving articles, bookmarking links, and highlighting text without processing or using the content.
The forgetting curve is Ebbinghaus's finding that memory decays exponentially after initial learning — losing roughly 50% within a day and 80% within a week without review.
The Leitner system is a manual spaced repetition method using physical flashcard boxes — cards you know well move to boxes reviewed less frequently; cards you struggle with stay in boxes reviewed daily until you master them.
The Lindy effect is the principle that for non-perishable things — ideas, books, technologies, institutions — the longer something has already survived, the longer it's expected to survive. Age predicts future longevity.
The Pareto principle for reading applies the 80/20 rule to information intake: roughly 20% of what you read produces 80% of the value. Identifying and focusing on that 20% dramatically improves knowledge quality and reduces overload.
The SM-2 algorithm is the mathematical formula that powers Anki and many other spaced repetition systems — it calculates precisely when to show you each flashcard based on how well you recalled it last time.
The Zeigarnik effect is the finding that unfinished tasks are remembered better than completed ones — your brain keeps open loops active in working memory until they're closed.
