Chunking (Miller)
Miller's term for the cognitive operation that transcends the seven-item limit without exceeding it — the packaging of multiple items into a single retrievable unit, transforming nine unfamiliar letters into three familiar acronyms and, at civilizational scale, transforming complexity into manageable thought.
Chunking is the mechanism by which the human mind transcends its own limitations without actually expanding them. Present someone with the sequence F-B-I-C-I-A-I-B-M and they will typically fail to hold all nine letters in working memory. Present the same letters as FBI, CIA, IBM and the task becomes trivial. The information has not changed; the packaging has. Three familiar acronyms occupy three slots where nine unfamiliar letters would have required nine. This is not a mnemonic trick but the fundamental mechanism of human expertise. What distinguishes the chess master from the novice is not superior calculation but superior chunking: the master sees not thirty-two pieces on sixty-four squares but a small number of familiar patterns — a Sicilian defense structure, a kingside pawn storm, a weak backward pawn. Each pattern is a chunk. Both master and novice have seven slots. The master's slots contain more.
