The argument contains information that seems impossible to have obtained—like it came from an omniscient author. This kind of writing/storytelling is characteristic of fiction, so when it is used in an argument it should cast doubt.
Examples:
- God wants us to love each other, but he is okay with us killing each other if we are defending our land—we will still go to Heaven.
Synonyms: argument from omniscience, “how the hell can you possibly know that?”
