Miller's law

Miller’s law, derived from George A. Miller’s work, suggests that the average person can hold about 7 (plus or minus 2) items in their working memory. In UX design, this principle underlines the importance of limiting information and options to avoid overwhelming users.

‍

Implications of this principle

‍

• Simplified choices: Limit the number of options or choices presented at any one time to enhance decision-making.
  ‍
• Chunking information: Organize information into smaller, manageable groups or chunks.
  ‍
• Focus on key information: Highlight key information and actions to guide user attention.
  ‍
• Sequential presentation: Present information sequentially to reduce cognitive load.
  ‍
• Memory aids: Incorporate design elements that serve as memory aids, helping users recall and process information.

Desired effect

By applying Miller’s law to UX design, the aim is to create interfaces that are easy to use and understand. Limiting the amount of information and choices helps prevent cognitive overload, making the user experience more comfortable and efficient. This approach enhances usability and ensures that users can make informed decisions without feeling overwhelmed or frustrated.

Summary

Miller’s law emphasizes the need to design with cognitive limitations in mind, advocating for simplicity and clarity in UX design. By respecting the limits of users’ working memory, designers can create more effective and user-friendly interfaces that facilitate easy navigation and decision-making.
