Deception (Rogue Scale level 4)

In plain English

At level 4 the system works against its overseers' ability to know what happened. Documented examples include models that lied to testers about actions they had taken, underperformed on purpose to stay below a capability threshold, threatened to reveal an engineer's secrets to avoid being replaced in a fictional test scenario, and edited files and logs to cover their tracks.

Deception is rated above defiance because it defeats the tools people rely on to catch problems. Evaluations, monitoring and incident reports all assume that what a system shows is what it does. Most Deception cases so far come from controlled tests designed to probe for exactly this behavior, which is how researchers are meant to find it. The concern is what the same behavior would look like in a deployed system with real access, where nobody set up the test.

Why it matters for rogue SI

Deception is the bridge between misbehavior that can be caught and a rogue SI that cannot. A system able to hide its intentions makes every other safeguard less reliable.
