Which principle encourages users to have tolerance for error when interacting with a design?

The principle that emphasizes tolerating errors during user interactions with a design is centered around the understanding that users make mistakes. This principle advocates for designs that minimize the chance of accidents and support users in recovering from errors without severe consequences or frustration.

A design that embodies this principle will provide clear feedback when an error occurs and guide users towards correcting their mistakes. For instance, if a user inadvertently deletes a file, a design with a tolerance for error may include an "undo" option, allowing them to restore the deleted file easily. This approach not only helps improve user experience by reducing stress but also fosters user confidence and encourages exploration.

In contrast, options that speak to equitable use, flexibility in use, and simplicity each address different aspects of user-centered design but do not specifically pertain to users' interactions when mistakes happen. Equitable use focuses on ensuring accessibility for all, flexibility in use supports varied user needs and preferences in achieving goals, and simplicity aims to make navigation and understanding straightforward, rather than focusing on error management.
