The Magic Number 7

Psychologist George Miller found that most people can hold 7 plus or minus 2 items in short-term memory. This is why phone numbers are 7 digits long. With practice, you can improve by chunking digits into groups.

How to Improve

Group digits into chunks (e.g., 583291 becomes 583-291). Create associations or stories with the numbers. Practice regularly — memory span improves with training, like any other skill.
