What is Mind Mapping?
Mind mapping is a note-taking method that arranges ideas as a radial diagram: a central topic branches into subtopics, keywords, and images instead of linear sentences. Popularized by Tony Buzan, it externalizes the structure of a subject, and controlled research shows a recall benefit for written material.
A mind map starts with the subject in the center of the page and grows outward through labeled branches, forcing two useful decisions at every step: what the key concepts are and how they relate. That makes mapping a generative activity rather than transcription, and the resulting spatial layout gives memory visual structure to hang on, in line with dual coding theory.
The best-known controlled test, by Farrand, Hussain, and Hennessy with medical students, found that the mind map group showed better factual recall of written material than students using their own preferred study methods, although many students were less motivated to use the assigned technique. The evidence base is thinner than for retrieval practice or spacing, so mapping is best treated as a strong organizing and planning tool rather than a proven memory system on its own.
For readers, mapping shines after capture: turning the highlights from an article or chapter into a one-page map is a compact test of whether you can reconstruct the argument's structure, and the gaps you cannot place reveal what to reread.
