Miller’s Law predicts that the average person can only keep 7 (± 2) items in their working memory.
In 1956, a psychologist, George Miller performed research in which he found what he believed to be the limit of the human ability for processing information. He found that most people stored 7 things plus/minus 2 in their short-term memory.
This was particularly significant for first-time users. Because they haven’t had the time to encode the information into long-term memory.
The law also highlights the importance of foresight and proper planning in the design process, because as you add more features to a product — your interface must be able to accommodate those new features without breaking the visual foundation of what you built. Rebuilding a foundation takes immense time and resources.
