George A. Miller

The mind holds about seven things

An American psychologist who measured the limits of the human mind and helped found cognitive science.

We escape memory's limits by grouping the world into meaningful chunks.
— George A. Miller

Who they were

George Miller noticed that across very different tasks people could juggle only about seven items at once, a regularity he captured in his famous paper on the "magical number seven." He showed how we slip past that bottleneck by chunking — grouping small pieces into larger, meaningful units. With colleagues he reimagined behavior as guided by plans and feedback loops rather than simple reflexes. His writing helped turn the study of mind into the new field of cognitive science.

Information Processing Theory

George A. Miller treated the mind as a system that takes in, stores, and works on information much like a computer. His famous observation was that short-term memory holds only about seven items at once, give or take a couple.
