The idea
Short-term recall has limits, and grouping information into familiar units can change how much people retain. Miller’s 1956 paper discusses several related limits; it does not prescribe seven items per interface.
Why it matters
Tasks become harder when people must keep details in memory while moving between screens. Visible context and meaningful grouping reduce that burden.
A real-world example
A bank transfer review keeps the recipient, amount and reference together so the sender can check them without remembering values from earlier screens.
What this doesn’t mean
Do not cap navigation at seven links or split every list into arbitrary groups. Recognition is different from recall, and memory capacity depends on the material and task.
Try this.
Keep information needed for a decision visible together. Group by meaning and provide a review step for consequential actions.
