Hoping to find the exact term for situations like the following:
Example: An online profile mentions that the person is drama-free. If they were actually drama-free, they would not need to mention it in the first place.
Another example: You walk into an interview and immediately tell your potential employer that you are not a robot.
Another example: Mentioning that the project details are subject to OPSEC is a violation of OPSEC.
I've heard several phrases that allude to the concept: "Don't make it a thing if it isn't a thing." "Keep it self-evident."
It's an oddly-specific type of catch-22 where it's taboo to bring something up in conversation without the other person becoming suspicious as to why you even mentioned it.
