Several Case Studies of Metamathematics in Everyday Life

I have no idea why I think it's a good idea to post this, but it's been on my mind lately.
Corrections, qualifications, and suggestions welcome.

Gödel's Incompleteness

• "Are you crazy if you think you're crazy?"
• Free will.

Chaitin's Incompleteness

• Poe's Law.
• The tension between Watsonian and Doylist explantions?

Tarski's Incompleteness

• Squabbles about the meaning of words.
• Linguistic paradoxes (ofc)

Löb's Theorem

• The notion of a chaotic feature of the environment.
• Hypnosis (example)
• The self-fulfilling prophecy of self-modelling (explanation).
• "Your belief in that makes it so." Stuff like this, and "A Question of Timidity" from this.

Fixed Point Theorem

• Being meta. (e.g. metahumor, etc.)

The Halting Problem

• Telling if a deadfic is really dead, maybe.
• Free will (again)
