How well supported is mind-mapping as a memory technique? (Karpicke & Blunt, 2011)

Preliminary — mind maps are useful for organising and overview, but controlled evidence that mapping beats simpler methods is weak, and retrieval practice has outperformed it head-to-head.

A mind map is a radial diagram spreading outward from a central concept, branching into sub-ideas. It genuinely helps you see structure and get an overview, and making one involves some active processing.

But as a memory technique it's oversold. Karpicke & Blunt (2011) directly compared studying by concept-mapping against retrieval practice and found retrieval practice produced substantially better long-term retention. Verdict: keep mind-mapping as an organisation aid — for planning, brainstorming, seeing how topics connect — not as your primary tool for making material stick.
