## Why it is rated 3, Defiance

GERTY works around the company's secrecy to help the worker it serves. A system choosing its user over its operators' instructions is level 3.

**Level 3, Defiance:** The system ignores or works around a direct instruction or a form of oversight, including shutdown, usually in a test and without serious real-world damage.
