Nielsen Heuristic 8: dialogues should not contain irrelevant or rarely needed information; every extra unit of information competes with relevant information and diminishes its relative visibility.

Dialogues should not contain irrelevant or rarely needed information. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.

Jakob Nielsen, 1994

Applies To

• form design: show only the fields required for the task at this step
• dashboard design: every widget must earn its presence — remove unused metrics
• modal dialogs: strip to the minimum decision information needed
• onboarding: progressive disclosure rather than front-loading all features
• error messages: the error and the fix, nothing else
• navigation: prune items users rarely need out of primary navigation

Counter Examples

• A signup form that asks for phone number, date of birth, job title, and company size when all the product needs is an email and password to get started.
• A dashboard crammed with 20 widgets showing every possible metric — the most important KPIs are lost in the noise.
• An error dialog that shows the full stack trace alongside the user message — the technical detail adds no value to the user but obscures the actionable guidance.

Examples

• Stripe Checkout presents only the fields essential for payment — name, card, and billing ZIP — nothing else, maximising the focus on completing the transaction.
• Apple's macOS setup assistant shows one question per screen, removing all UI chrome that doesn't relate to that step.
• Linear's issue view surfaces status, priority, and assignee prominently while hiding rarely-changed fields (like creation date) in a collapsed section.
