Which principle focuses on tolerating errors and minimizing hazards?

• A. Simple and Intuitive Design
• B. Perceptible Information
• C. Appropriate Space for Approach and Use
• D. Tolerance for Error

Answer: (D)

Tolerating errors means designing so mistakes don’t turn into serious hazards and users can recover quickly. It’s about guiding people safely when something goes wrong by making mistakes easy to undo, providing clear and immediate feedback, and offering safeguards or confirmations for actions that could have dangerous or irreversible consequences. In practice, this translates to features like undo or cancel options, warning prompts before deleting data or making irreversible changes, and defaults that favor safety. It also includes designing controls and layouts that help prevent accidental actions in the first place and that allow quick recovery if a mistake happens. While simple and intuitive design helps people understand how to use something, and perceptible information ensures cues are visible, and adequate space supports access and maneuverability, none of those specifically center on reducing risk after errors in the way tolerance for error does.
