What is this GUI principle called?

Question

"Prefer to design UI that guides the user to provide correct input before submitting a form over presenting an error message when he submits it incorrectly"

Is there a canonical link that explains this (similar to KISS)?

The following links would help you as well (based on user-centric interface design):

• User Interface Design
• Experience Design

Answer 2

Would you accept the following?

An ounce of prevention is better than a cure.
