Is it true that George A. Miller's paper The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information suggests there are limits to human cognitive processing capacity?

Yes. George A. Miller's seminal paper proposing limits on human information processing capacity remains a foundational concept, supported by contemporary research on working memory limits, chunking, and cognitive architecture.

Verdict: SUPPORTED · 5 sources for, 0 against · Last checked 4 Oct 2026

The analysis

The claim is a specific, well-established historical and empirical proposition about George A. Miller's work on human cognitive capacity limits. The retrieved literature overwhelmingly supports the existence of working memory capacity limits and frequently cites or builds upon Miller's foundational observations regarding the magical number seven and chunking.
