This is a refusal to accept a well-proven argument for one of many reasons related to stubbornness. It can also be the refusal to argue about a claim that one supports.
Examples:
- Dad: You are failing math since you moved the Xbox to your room. You have been playing video games for at least 6 hours each day since. Before that, you consistently got A’s and B’s. Don’t you think that the video games are the real problem here? Blake: No.
Synonyms: argument by stubbornness, invincible ignorance fallacy
