the magical number seven

The "magical number seven" refers to a concept in psychology known as Miller's Law, proposed by cognitive psychologist George A. Miller in 1956. It suggests that the average person can hold about seven pieces of information in their working memory at one time. This means when trying to remember phone numbers, lists, or ideas, grouping them into sets of seven or fewer can improve recall. This principle highlights the limitations of our short-term memory and has implications for education, communication, and technology, influencing how we design information presentations and user interfaces.
