The Magical Number Seven, Plus or Minus Two is one of the most highly cited papers in psychology. It was published in 1956 in Psychological Review by the cognitive psychologist George A. Miller of Princeton University’s Department of Psychology. It is often interpreted to argue that the number of objects an average human can hold in working memory is 7 ± 2. This is frequently referred to as “Miller’s Law.”
